mysqli_connect not working on MAMP - mysqli

The code below worked on my old iMac with MAMP. However, it does not work on my new iMac. How do I fix this? Do I need to do something to the php.ini file?
<?php
$dbConnection = mysqli_connect("localhost", "xxxx", "xxxx", "gallery");
$query = "SELECT * FROM images";
$stmt = mysqli_prepare($dbConnection,$query);
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $id, $categories,$img_name);
while (mysqli_stmt_fetch($stmt)) {
echo $id."<br />";
}
?>


I grappled with this one for most of a day before the following on the (localhost) MAMP home page caught my eye: if you're running a PHP version 5.5.x or earlier, mysqli_connect() should work fine, but if you're using PHP version 5.6.x or later, try mysqli_init() and see if that works for you. It worked for me! It displays under the heading "Examples". Good luck!


You should enable php_mysqli extension in PHP.ini. It's disabled by default.
look for the following line: extension=php_mysqli


The problem: a column name was missing from the bind statement.

Moodle can't redirect to page after installation

I have just installed Moodle on my web-server. Everything was OK until I came to page where I saw this text: "This page should automatically redirect. If nothing is happening please use the continue link below. Continue."
When I click on Continue, the same page shows again. I deleted all data from moodledata folder (saw it on this site), but I have the same problem again and again. What can be a problem here and how to solve it?
Thank you in advance.

The first step to do is to enable debugging. I assume you can not access site administration anymore so you have to enable debugging in the config.php file. The file is located in /path/to/moodle/config.php (that means in the root folder of your Moodle installation).
The first lines should look like that in config.php. That means you have to add the 4 lines which are under $CFG = new stdClass();
<?php // Moodle configuration file
unset($CFG);
global $CFG;
$CFG = new stdClass();
#error_reporting(E_ALL | E_STRICT); // NOT FOR PRODUCTION SERVERS!
#ini_set('display_errors', '1'); // NOT FOR PRODUCTION SERVERS!
$CFG->debug = (E_ALL | E_STRICT); // === DEBUG_DEVELOPER - NOT FOR PRODUCTION SERVERS!
$CFG->debugdisplay = 1; // NOT FOR PRODUCTION SERVERS!
After that open Moodle in your browser. A debug message will be displayed. Post the error message in order to get additional help so solve the problem.

Class 'mPDF' not found in Yii2

I have problem with my page on server.
I'm using yii2 framework and mPDF;
All configured according to the instructions: http://www.bsourcecode.com/yiiframework2/create-pdf-files-using-mpdf-in-yiiframework-2-0/
Page work on localhost on Windows and Xampp
When I try run page on Debian 8 I have error:
Class 'mPDF' not found
Configuration: http://www.bsourcecode.com/yiiframework2/create-pdf-files-using-mpdf-in-yiiframework-2-0/
function in php:
public function actionCreatepdf()
{
$request = Yii::$app->request;
$generate_table = $request->post();
$mpdf = new mPDF;
$mpdf->WriteHTML($this->renderPartial('view_pdf', ['data'=>$data]));
$mpdf->Output('data.pdf', 'D');
exit;
}
I have no idea what I'm doing wrong, it's not running on Debian

I had this issue when migrating from Ubuntu (php 5.6) to CentOS 7 (PHP 7.1)
The easiest thing to do, without manually editing the composer file was to change the use/import in the controller:
//use mPDF; #Php 5.6
use Mpdf\Mpdf; #Php 7.0

Solved! As mentioned before it was due to capital cases.
I used following and it is now working on CENTOS 7 (probably similar on most Linux versions)
<?php
namespace app\controllers;
use Yii;
//use mPDF; Note this line is Commented out
use mpdf;
And then use it as follows:
public function actionIndex(){
$model = new Mpdf();
$model->SetHeader('header');
$model->WriteHTML("PDF contents");
$model->SetFooter('footer');
$model->Output('MyPDF.pdf', 'D');
exit;
}

In my case which i just resolved, adding
'mPDF\' => array($vendorDir . '/mpdf') to autoload_psr4.php required me to namespace most of the class files in ../mpdf/classes using the line
namespace mPDF;
Also among the errors i fixed was changing include to include_once to prevent php from seeing some classes as duplicate declaration despite the presence of class_exists() test

php fopen with ssh2.sftp is failing with special characters

The below is working just fine
$stream = fopen($connection_string . "/var/tmp/test.test", 'r');
But
$stream = fopen($connection_string . "/var/tmp/test.#test", 'r');
Fails with an error message:
Warning: fopen(): Unable to open ssh2.sftp://Resource id #108/var/tmp/test.#test on remote host in...
test.test and test#test are working fine, only the combination of test.#test is failing.
ssh2_scp_recv() handles test.#test just fine.
CentOS release 5.8 (Final)
PHP 5.2.17
Is this a php bug? Or some special character escaping is required?

it would be interesting to know how well it works with phpseclib. eg.
<?php
include('Net/SFTP.php');
$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
exit('Login Failed');
}
// outputs the contents of filename.remote to the screen
echo $sftp->get('filename.remote');
// copies filename.remote to filename.local from the SFTP server
$sftp->get('filename.remote', 'filename.local');
?>
src: http://phpseclib.sourceforge.net/sftp/examples.html#get
if phpseclib didn't work you could enable logging, with phpseclib, and see what the phpseclib logs say. eg. do define('NET_SSH2_LOGGING', NET_SSH2_LOG_COMPLEX); after you include Net/SFTP.php and then do $sftp->getLog() after you try to download the file.

Opencart Fatal error: Call to a member function get() on a non-object

Trying to move from local host to new server. Fresh install worked fine, no problems. When I uploaded my files mydomain.com/admin comes up with a white screen and mydomain.com produces this error:
Fatal error: Call to a member function get() on a non-object in /home4/pawpostc/public_html/index.php on line 103.
So I took a look at index.php line 103:
if ($config->get('config_error_display')) {
echo '<b>' . $error . '</b>: ' . $errstr . ' in <b>' . $errfile . '</b> on line <b>' . $errline . '</b>';
}
Seems like there is a problem with my config files. So I went and had a look at them. I have gone over them a few times but can not find the mistake, probably missing something, so here are the config files.

Any help on this would be appreciated.

I was using opencart and installed vqmod.
All of a sudden I have one of the same errors.
This solved my problem:
in system/library/session.php
replace start session with:
session_save_path(realpath(dirname($_SERVER['DOCUMENT_ROOT']) . '/../tmp'));

The most likely issue is that one or more of your library files are corrupt from uploading. Re upload your system/library/ folder from your local one. Your config files seem fine and the error doesn't reference a config issue. What is line 103 in your index.php file?

please cross check you have set all permissions
i had came across this error and was solved,
that was due to a file permission problem

I was struggling with the same problem after migrating my site to a new VPS environment. I figured it HAD to be something to do with the changed document-root path or permissions of my shop and pulled out a lot of hair trying to get to the core of the problem.
I finally realised that I had incorrect permissions on my PHP session-data store! In my case, the folder at /var/lib/php/session/ was owned by apache (naturally) but I had changed apache to run as a different user so it could no longer write to the session-store.
The error messages in this case are cryptic (to say the least!) and didn't give a clue that the problem might just be lack of write permission!
Oh well, we should know by now that 90% of unix issues are down to perms!

I upload a file at my server (directory: vqmod/....php ).
Just change vqmod file permission. I set 777 and that solved it.

From the error you received, it looks like the $config variable is not getting set.
The $config variable is set on line 35 using the Config class which is located in system/library/config.php
I think if you figure out why the class isn't getting instantiated, you'll be able to fix the issue.
This could be a couple things:
The system/library/config.php file may not have been uploaded to the new server
As mentioned in previous answers, there could be a permissions issue. Check the permissions of system/library/config.php and make sure the correct user has ownership.
Or it could be a completely unrelated issue.

The error is due to permissions set on the cache folder. Setting that to 755 and the files to 555 with set you home and dry.

I had the same issue. I changed vqmod permission to 777. I am not sure this solved the problem, but I checked my website without adding www. before the domain and it worked. The warning was removed if I check http://daytodaystore.com. If I check http://www.daytodaystore.com, the warning is there.

I had this problem when i migrated my server from 2G to 4GH on Godaddy.
Came across this forum and found that the issue is with session.php
Then, i guessed 'tmp' folder was missing. So, i created one just one step above html folder. and gave it a 777 access. Problem was fixed and my website looks great after that.

memcached not working on codeigniter 2.1.0

I have been trying to make it work for sometime now, but I can't. I am working on a Windows 7 64bits, I have the Memcached Server running as Service, I have the php_memcached.dll extension in the PHP 5.3.8 and when I call it on the app in Codeigniter I do it the right way (I Think).
$this->load->driver('cache', array('adapter' => 'memcached', 'backup' => 'file'));
var_dump($this->cache->memcached->is_supported());
die();
but it throws a false so I don't know what I am doing wrong. When I call it like this:
$this->load->driver('cache', array('adapter' => 'memcached', 'backup' => 'file'));
$data = $this->cache->memcached->get('data_' . $idData);
I get this PHP error:
Fatal error: Call to a member function get() on a non-object in E:\workspace\example\system\libraries\Cache\drivers\Cache_memcached.php on line 50
Thanks for the help :-)

The CI driver is looking for the Apache Module, but in WIN we use mostly the PHP-Class Memcache.
Try to change Line 165 in /system/libraries/Cache/drivers/Cache_memcached.php
$this->_memcached = new Memcached();
For me it works after changing from Memcached to Memcache.
$this->_memcached = new Memcache();

I know this is old, but I just came across the same issue.
On Windows, you should be using "Memcache" rather than "Memcached". To do this, follow the instructions on this page:
http://www.leonardaustin.com/technical/how-to-install-memcached-on-xampp-on-windows-7
Then, to get it working in CI, you'll need to make two small changes to \system\libraries\Cache\drivers\Cache_memcached.php:
In function is_supported(), replace:
if ( !extension_loaded('memcached'))
With:
if ( !extension_loaded('memcached') && !extension_loaded('memcache'))
And in function _setup_memcached(), replace:
$this->memcached = new Memcached();
With:
if(class_exists("Memcached"))
$this->_memcached = new Memcached();
else
$this->_memcached = new Memcache();
