how will i apply preg_replace please???
thank you

im trying to do a complex(i think) prg replace but i keep getting the error:

Code: [Select]
Failed evaluating code: $lang->showing-1,1
the code i am trying to replace is:

Code: [Select]
<asf: lang[showing-<asf: var[num_report_alerts]>,<asf: var[num_report_alerts]>]>
and the preg_replace is:

Code: [Select]
$content = preg_replace('|\<asf: lang\[(.*?)-(.*?)\]\>|e', '$lang->replace_vars($lang->//1, array(\\2))', $content);
its supposed to take everything inside <asf: lang[]> and echo \\1 which would be "showing" and then add \\2 into an array which would be "array(1,1)".

So the output would be showing 1 of 1.

Anyone know where im going wrong?

I am trying to pull out the image HTML tag but its not working as expected.
Here is what I am doing
   $removeimagetag='/<a href/';
   $replacwith = "illegal";
$_POST['descr']=preg_replace($removeimagetag,$replacwith,$_POST['descr']);

in the 'descr' there is a <a href="http://s635.photobucket.com......
When it post it does not strip out the <a href
So the image is displayed.

I tried a modified version to test to see if it work that looked like this.

   $removeimagetag='/goofy/';
   $replacwith = "illegal";
$_POST['descr']=preg_replace($removeimagetag,$replacwith,$_POST['descr']);

When the word goofy appears in the text then its replaced with the word illegal,

Also I would like to make it so that it replaces the entire line from the <a href....... to the </a> with a phrase that says "this feature is not allowed"  rather than just the part in the front...the <a href.

Any help you can be will be greatly appreciated.

Hi there!

I need to echo some text from a database table, this text should be linked to a url stored in the same database. I am trying to do this with preg_replace but I am terrible at it! I keep getting this error:

Warning: Wrong parameter count for preg_replace()

while($row = mysql_fetch_array( $result ))
 {

$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";

echo preg_replace ($reg_exUrl, $row['title');


Any suggestion?

Thanks

I currently have some custom tags, similar to BBCode, to be used for comments on my site. I'm trying to create a [nobr] tag (note: I know the no break tag will work in many major browsers, but it's deprecated, so I'm trying to be compliant).

The idea is that if I encounter the [nobr] tag, I need to remove all line breaks. Here's the best I can do, but it's not working as I had hoped.

Here's what I currently use to replace line breaks with a break tag.
Code: [Select]
$str=str_replace("\r\n","<br>",$str);

Here's my attempt at introducing this new tag.
Code: [Select]
function BbToHtml($str) {

 $before=preg_replace("/(.+)\[nobr\](.+)\[\/nobr\](.+)/Usi","\\1",$str);
 $during=preg_replace("/(.+)\[nobr\](.+)\[\/nobr\](.+)/Usi","\\2",$str);
 $after=preg_replace("/(.+)\[nobr\](.+)\[\/nobr\](.+)/Usi","\\3",$str);

 $during=str_replace("\r\n","",$during);

 if($during != "") { // If the [nobr] tag was found, go with the new string.
  $str = $before.$during.$after;
 }
 else { // If the [nobr] tag was not found, go ahead like normal.
  $str=str_replace("\r\n","<br>",$str);
 }

 return $str;

I can't get that working. Any ideas on how to fix that, or a completely alternate method of doing it? Thank you!

After days of searching I found this thread http://www.phpfreaks.com/forums/index.php?topic=236954.0 that helped me do what I was trying to do.  I've gotten the code to create and rename my html document but I can't figure out how to use the preg_replace part.  This is my template with the 3 variables I want to replace with values from a form.

Code: [Select]
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<?php include_once('content.php') ?>
</body>
<SCRIPT language="JavaScript" SRC="javascript.js"></SCRIPT>
<script type="text/javascript">
function nametitle(){
parent.iframe1.document.getElementById("div1").innerHTML = "VARIABLE1
<br>VARIABLE2";
parent.iframe1.document.getElementById("quotes").innerHTML = "VARIABLE3";
}
</script>
</html>
I've spent hours reading and trying to understand how to make it work but it's a little over my head.  Could someone help me with this?

Thanks,

I'm trying to search a string for all occurences of a pattern, then append text after that pattern.  The example is:   SUM("foo") as "bar"   and have it display as:   SUM("foo") over() as "bar"   The "SUM" could be any SQL aggregate and be case insensitive.  So For bonus points, let's say the valid aggregates are  array('SUM', 'MAX', 'MIN', 'AVG').  My plan right now is to figure it out for SUM, then loop it replacing the aggregate.   This is what I have so far... and it is not working.   $l= 'SUM("foo") as "bar"'; $l=preg_replace('/([^"]+")/','\0 over()',$l);   Thanks,   Ryan

Hi,

I'm kind of new to PHP and very new to Regular Expressions and I was wondering if someone could help run through this code snippet from a callback function in a Joomla plugin called Affliates Feed.

So far I have this
is passed a pointer to variable item (I understand this is effectively the same as passing the variable but a lot less CPU intensive.
Creates an array with keys and values

Now the for loop I am stuck with, I understand the interation through the array. But what is preg_replace returning and why pass it back that way hasn't it already done its job?

Can any one help? And please feel free to be as basic as possible :help:

Thanks,
Adam


Code: [Select]
function gardening(&$item) {
   #renaming categories, not the most efficient use for example strtolower first, and use only lowercase in the rename array
   $rename=array(
      ' Gardening?' => '',
      'Climber Plants' => 'Climbing Plants',
      'Seeds.*Bulbs' => 'Seeds Bulbs',
      'Plant protection' => 'Horticultural goods',
      'Garden structures' => 'Garden buildings',);
   foreach ( $rename as $k => $v ) {
      list($item['menu_1'],$item['menu_2'])=preg_replace("#$k#",$v,array($item['menu_1'],$item['menu_2']));
   }
   $item['menu_1']=ucfirst(strtolower($item['menu_1']));
   $item['menu_2']=ucfirst(strtolower($item['menu_2']));
   $item['menu_3']=ucfirst(strtolower($item['menu_3']));
   $item['menu_4']=ucfirst(strtolower($item['menu_4']));
}

Hi, I've got a little problem at the moment with how to replace varying amounts of hyphens in a  browser url.

scenario:
I have a borwser url mydomain.com/location/foo-bar/ where "foo-bar" is actually "foo bar" in the database (no hyphen).
I also have urls where the entry in the database does have the hyphens e.g. "foo-bar"

Now im not quite sure how to go about writing these urls, and how to manipulate the GET values from them.

what I've tried

My first thought was to add a secondary hyphen to the url so that the database entires that equal "foo-bar" would be "foo--bar" in the browser url and the entries in the database that equal "foo bar" would have the single hyphen "foo-bar".

Then i would use preg_replace to deal with the single hyphens by removing them and replacing with a space, and after that finding the double hyphens and replacing them with only one.

In theory this should work (I think), but I've only recently got into using regex, this is what I've tried;

$CNE = preg_replace("/[-]{1}/", " ", $CNE);
$CNE = preg_replace("/[-]{2}/", "-", $CNE);


so I've tired to match the single hyphen and then the double, but even before I tested this I didn't think it was going to work with this code.


Can anyone correct me, or maybe suggest a better way to go about this issue.
(note: using a different character to replace spaces is NOT an option in this case)

Thanks
