When I moved to a new server, eregi function generates too many errors. I like to use preg_replace instead of eregi function.
Here is my block of code:
if($rstate && !$rcity && !eregi("outside",$rstate)){
$h1title=str_replace('DDD',$tsstate,str_replace('XXX',$tsstate,$pagetitlet));
echo str_replace('DDD',$tsstate,str_replace('XXX',$tsstate,$pagetitlet));
I changed it to:
if($rstate && !$rcity && !preg_replace("outside",$rstate)){
$h1title=str_replace('DDD',$tsstate,str_replace('XXX',$tsstate,$pagetitlet));
echo str_replace('DDD',$tsstate,str_replace('XXX',$tsstate,$pagetitlet));
But it is looking for another value. How do I add the third parameter for preg_replace to get it worked?
Thanks.
You don't need to use a regex for this test, use strpos instead:
if ($rstate && !$rcity && strpos($rstate, "outside")===false) {
$h1title = str_replace('DDD', $tsstate, str_replace('XXX',$tsstate,$pagetitlet));
echo str_replace('DDD', $tsstate, str_replace('XXX',$tsstate,$pagetitlet));
...
}
Note that the regex function you are looking for is preg_match

preg_replace to change be like
http://i.imgur.com/KKtAU8Xt.jpg
replace last dot to t.
try code
/\.([^.]*)$/ or /(.*)\.([^.]*)$/
add it remove .jpg too!
I need to keep .jpg
$ cat test.php
<?
$url = 'http://i.imgur.com/KKtAU8X.jpg';
$newUrl = preg_replace('#^(.+)\.([\w]+)$#i', '$1t.$2', $url);
var_dump($url, $newUrl);
$ php test.php
string(30) "http://i.imgur.com/KKtAU8X.jpg"
string(31) "http://i.imgur.com/KKtAU8Xt.jpg"
Am a newbie in Perl and need help with a small problem
Situation:
I have to execute a command line program through perl.
The arguments to this command line are email addresses
These email addresses are passed to me through another module.
Problem:
I have written the code to create the argument list from these email addresses but am having problem in running exec().
NOTE: If I pass hardcoded strings with escaped "#" character to the exec() as command args,it works perfectly.
Sub creating cmd args map
sub create_cmd_args {
my($self, $msginfo) = #_;
my #gd_args_msg = ('--op1');
my $mf = $msginfo->sender_smtp;
$mf =~ s/#/\\#/ig; ## Tried escaping #, incorrect results.
push #gd_args_msg, '-f="'.$mf.'"';
for my $r (#{$msginfo->per_recip_data}) {
my $recip = $r->recip_addr_smtp;
$recip =~ s/#/\\#/ig; ## Tried escaping #, incorrect results.
push #gd_args_msg, '-r="'.($recip).'"';
}
return #gd_args_msg;
}
Sub that uses this args map to exec the program
sub check {
my($self, $msginfo) = #_;
my $cmd = $g_command;
my #cmd_args = create_cmd_args($self, $msginfo);
exec($cmd, #cmd_args); ### ******* fails here
}
Sample run:
INPUT:
sender_smtp: <ashish#isthisreal.com>
receiver_smtp: <areyouarealperson#somedomain.com>
Could someone please guide me what is wrong here?
As an argument to a command in the shell,
-f="<ashish#isthisreal.com>"
causes the the string
-f=<ashish#isthisreal.com>
to be passed to the program. Your program passes
-f="<ashish\#isthisreal.com>"
to the program. The problem isn't the #; the problem is the " and \ you are adding.
my $mf = $msginfo->sender_smtp;
push #gd_args_msg, "-f=$mf"; # Assuming $mf is <ashish#isthisreal.com>
If you look at the post at Trying to convert Perl to PHP and the code within the md5sum implementation that calls the command line you will see an approach that will save you from needing to worry about escaping characters.
When you run a PHP script through a browser it looks something like
http://somewebsite.com/yourscript?param1=val1¶m2=val2.
I am trying to achieve the same thing via command line without having to rewrite the script to accept argv instead of $_REQUEST. Is there a way to do something like this:
php yourscript.php?param1=val1¶m2=val2
such that the parameters you send show up in the $_REQUEST variable?
In case you don't want to modify running script, you can specify parameters using in -B parameter to specify code to run before the input file. But in this case you must also add -F tag to specify your input file:
php -B "\$_REQUEST = array('param1' => 'val1', 'param2' => 'val2');" -F yourscript.php
I can't take credit for this but I adopted this in my bootstrap file:
// Concatenate and parse string into $_REQUEST
if (php_sapi_name() === 'cli') {
parse_str(implode('&', array_slice($argv, 1)), $_REQUEST);
}
Upon executing a PHP file from the command line:
php yourscript.php param1=val1 param2=val2
The above will insert the keys and values into $_REQUEST for later retrieval.
No, there is no easy way to achieve that. The web server will split up the request string and pass it into the PHP interpreter, who will then store it in the $_REQUEST array.
If you run from the command line and you want to accept similar parameters, you'll have to parse them yourself. The command line has completely different syntax for passing parameters than HTTP has. You might want to look into getopt.
For a brute force approach that doesn't take user error into account, you can try this snippet:
<?php
foreach( $argv as $argument ) {
if( $argument == $argv[ 0 ] ) continue;
$pair = explode( "=", $argument );
$variableName = substr( $pair[ 0 ], 2 );
$variableValue = $pair[ 1 ];
echo $variableName . " = " . $variableValue . "\n";
// Optionally store the variable in $_REQUEST
$_REQUEST[ $variableName ] = $variableValue;
}
Use it like this:
$ php test.php --param1=val1 --param2=val2
param1 = val1
param2 = val2
I wrote a short function to handle this situation -- if command line arguments are present and the $_REQUEST array is empty (ie, when you're running a script from the command line instead of though a web interface), it looks for command line arguments in key=value pairs,
Argv2Request($argv);
print_r($_REQUEST);
function Argv2Request($argv) {
/*
When $_REQUEST is empty and $argv is defined,
interpret $argv[1]...$argv[n] as key => value pairs
and load them into the $_REQUEST array
This allows the php command line to subsitute for GET/POST values, e.g.
php script.php animal=fish color=red number=1 has_car=true has_star=false
*/
if ($argv !== NULL && sizeof($_REQUEST) == 0) {
$argv0 = array_shift($argv); // first arg is different and is not needed
foreach ($argv as $pair) {
list ($k, $v) = split("=", $pair);
$_REQUEST[$k] = $v;
}
}
}
The sample input suggested in the function's comment is:
php script.php animal=fish color=red number=1 has_car=true has_star=false
which yields the output:
Array
(
[animal] => fish
[color] => red
[number] => 1
[has_car] => true
[has_star] => false
)
I have a simple Joomla controller, but I can't redirect anything.
According to the documentation:
class MyController extends MyBaseController {
function import() {
$link = JRoute::_('index.php?option=com_foo&ctrl=bar');
$this->setRedirect($link);
}
}
//The url contains & html escaped character instead of "&"
This should work, but I get a malformed URL. Is there something I'm missing here? Why is Joomla converting all the "&" characters into &'s? How am I suppose to use setRedirect?
Thank you
Alright, I fixed it. So if anyone needs it:
instead of
$link = JRoute::_('index.php?option=com_foo&ctrl=bar');
$this->setRedirect($link);
use
$link = JRoute::_('index.php?option=com_foo&ctrl=bar',false);
$this->setRedirect($link);
to make it work.
Glad you found your answer, and by the way, the boolean parameter in JRoute::_() is by default true, and useful for xml compliance. What it does is that inside the static method, it uses the htmlspecialchars php function like this: $url = htmlspecialchars($url) to replace the & for xml.
Try this.
$mainframe = &JFactory::getApplication();
$mainframe->redirect(JURI::root()."index.php?option=com_foo&ctrl=bar","your custom message[optional]","message type[optional- warning,error,information etc]");
After inspecting the Joomla source you can quickly see why this is happening:
if (headers_sent())
{
echo "<script>document.location.href='" . htmlspecialchars($url) . "';</script>\n";
}
else
{
... ... ...
The problem is that your page has probably already output some data (via echo or some other means).
In this situation, Joomla is programmed to use a simple javascript redirect. However, in this javascript redirect it has htmlspecialchars() applied to the URL.
A simple solution is to just not use Joomlas function and directly write the javascript in a way that makes more sense:
echo "<script>document.location.href='" . $url . "';</script>\n";
This works for me :)
/libraries/joomla/application/application.php
Find line 400
// If the headers have been sent, then we cannot send an additional location header
// so we will output a javascript redirect statement.
if (headers_sent())
{
echo "<script>document.location.href='" . htmlspecialchars($url) . "';</script>\n";
}
replace to
// If the headers have been sent, then we cannot send an additional location header
// so we will output a javascript redirect statement.
if (headers_sent())
{
echo "<script>document.location.href='" . $url . "';</script>\n";
}
This works!
I needed to write a custom module in drupal to help out with my location search. Initially I simply needed to remove a comma from queries, and then I realized that I would need to replace all instances of states with their abbreviation (California -> CA) because of how information is stored in my database. However, upon doing this I found out that my method of using preg_replace seems to be dependent on upper/lowercase. So in this line:
$form_state['values'] = preg_replace("/alabama/", 'al', $form_state['values']);
"alabama" will be replaced with "al", but "Alabama" or "ALABAMA" will not. Is there a way to replace any instance of Alabama with its abbreviation without accounting for every possible variation in casings?
you can try also str_ireplace() it's Case-insensitive
<?php
$str = 'alabama ,Alabama,ALABAMA';
$replace = str_ireplace('alabama','al',$str);
echo $str;
echo "<br/>";
echo $test;
?>
$form_state['values'] = preg_replace("/alabama/i", 'al', $form_state['values']);
The 'i' modifier will make the pattern case-insensitive.
