PHP - Problem With Preg Replace?

Code: [Select]
$text = preg_replace('{-(\d+)}e', '-convertNumber("$1")', $text);
i have strings im trying to replace like this:

name-2 > name-two
name-p2 > name-p2

im trying to match and replace the first one and basically ignore the second one. ive included the hyphen in the code. so why isnt this working?

Code: [Select]
line 129- function filterBadWords($str)
 {
    $result = mysql_query("SELECT badwords FROM clean") or die(mysql_error());
    $replacements = "*";
   
    while($row = mysql_fetch_assoc($result))
    {     
          $bad_words= $row['badwords'];
          $spaced_bad_words = preg_replace("/(.)/i", "\${1} ", $bad_words);
          $spaced_bad_words = trim($spaced_bad_words);
          $str = preg_replace("/$bad_words | $spaced_bad_words/i", str_repeat('*', strlen($bad_words)), $str);
    }
   
    return $str;
Line 143 - }

i keep getting this at top of page
Warning: preg_replace() [function.preg-replace]: No ending delimiter '`' found in C:\xampp\htdocs\socialtscripts\activation.php on line 16
here is the code that it is reffering to
Code: [Select]
preg_replace("`", "", $id);

I've never really made my own bbcode parser function before, but I'm going off of different tutorials to help me create my own style of parsing.  I've actually never really used preg_replace much, either.  My code is returning an odd error and I have no idea how to fix it.  I'm using codeigniter and the error it returns is below:

Quote

preg_replace() [function.preg-replace]: Compilation failed: nothing to repeat at offset 6


This is the code for my function:
Code: [Select]
function bbParse($string){

$codes = array(
'/\[b\](*?)\[\/b\]/' => '<b>\\1</b>', //bold tags
'/\[h2\](*?)\[/h2\]/' => '<h2>\\1</h2>', //h2 tags
'/\[h3\](*?)[\/h3\]/' => '<h3>\\1</h3>', //h3 tags
'/\[quote\](*?)\[\/quote\]/' => '<blockquote>\\1</blockquote>', //quote tags using the template's blockquote tag
'/\[img\](*?)\[/img\]/' => '<img src=\'\\1\' alt=\'Image Not Available\'>', //image tags
'/\[url\=(*?)\](*?)\[/url\]/' => '<a href=\'\\1\' title=\'\\2\'>\\2</a>', //anchor tags
'/\[p\](*?)\[/p\]/' => '<p>\\1</p>' //paragraph tags
);



$string = preg_replace(array_keys($codes), array_values($codes), $string);

return $string;


}

How do I fix this For Each statement when used with preg match?

//Cat_ID  &  Category Name
preg_match_all('%<a[^href=]*href=\"\/cats\.asp\?cat_id=(.*?)\" title="(.*?)">%',$data,$matches1,PREG_SET_ORDER);  // works fine 
preg_match_all('%/60/(.*?).jpg"%s',$data,$matches2,PREG_SET_ORDER); // works fine
preg_match_all('%h3><p>(.*?)<\/p>%s',$data,$matches3,PREG_SET_ORDER); // works fine

foreach ($matches1 as $val) {        //need help here
$subcat_id=$val[0][1];
$subcat=$val[0][2];
$cat_image=$val[1][1];
$cat_desc=$val[2][1];



Thanks for your help!!!

Hey guys i am trying to search all href in a string and add someting in front so i can catch some stats before i redirect the user.

For exemple : href="http://twitter.com"
Should be changed into: http://test.ca?dat='.urlencode("http://twitter.com").'

But i can't get it to work ...

so what i got so fare is
<?php

$str = "<a target='_blank' href='http://twitter.com'>TEST 1</a> <a target='_blank' href='http://twitter.com'>TEST 2</a>";
$str .= ' <a href="http://twitter.com">TEST 1</a> <a href="http://twitter.com">TEST 2</a>';

function matche($matches){
$url = str_replace('http://', '', $matches[1]);
$url = str_replace('www.', '', $url);
return 'href="http://test.ca?email=XX_EMAIL&nid=XX_ID&dat='.urlencode($url).'"';
}

echo preg_replace_callback("/href=['\"]([.*]+)['\"]/","matche",$str);

?>

I have a number of records of the html sections of a series of Google Earth placemarks
that I managed to extract from the raw kml file. The purpose of the  exersize was to then use
the simplehtmldom.php api to extract the DATA from the raw html code. Some of the process is
going well... and some  is NOT.

I have found that if I modify the raw html code by entering ID attributes into the html code
the simplehtmldom api has an easy time identifying the desired data, and the data can be far
'cleaner' by entering an id attribute as 'close' to the data as possible. But doing a php text search
and replace often requires finding a 'unique' identifyable portion of the html code and THEN placing
the 'id' attribute in a nearby html tag because the desired data is nested inside a non-unique tag.
As in I can identify a SPECIFIC <td> tag section where the data i desire is located but the data
is nested inside a <font>  tag inside the <td> cluster.

Hence my problem...

If I do a search in the following  code...
Code: [Select]
<td><b><font size="+2" color="#FF0000">Neighborhood:</font>&nbsp;<font size="+2" color="#0000FF">City of Sidney</font></b></td>

I can locate the 'Neighborhood:' string because it is unique in the whole html code. Then by some
charcter counting I am desiring to put my 'id' attribute in the NEXT font tag because it surrounds
the desired data the 'City of Sidney'... as in...

Code: [Select]
<td><b><font size="+2" color="#FF0000">Neighborhood:</font>&nbsp;<font id="neighborhood" size="+2" color="#0000FF">City of Sidney</font></b></td>
With this modification the desired data is easily found and  cleanly produced.

But the html code while all operating correctly in a web page is not all identicle from a
'whitespace' point of view AND thus my problem. If I search the following code...
Code: [Select]
<td>
    <b><font size="+2" color="#FF0000">Neighboorhood:</font>&nbsp;
       <font size="+2" color="#0000FF">Greenacre</font></b>
  </td>
While being identical as far as html is concerned if I search this code for the 'Neighboorhood:'
identifier I find it... but then attempting to place the id tag into the NEXT font tag is being
problematic. What i seem to need is a function that once the 'Neighboorhood:' string position is
identied and noted in the whole of the html code, to FIND and modify the NEXT occurance of
a font tag no matter what whitespace (or special charachters) may be occuring.

Any suggestions??

The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it.   For example:

<?php
$str = 'some blob ~abc~ followed by ~def~';

$arr_orig = array(
	'~abc~',
	'~def~'
);

$arr_new  = array(
	'value~def~',
	'blah'
);

echo str_replace( $arr_orig, $arr_new, $str );
?>

This will echo: some blob valueblah followed by blah   But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need.   I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!)

Hi
i wrote a find and replace code but my code replace last value of array and skip the first, second.... values in the array.
Please give me an idea because i stack with this code.

Regards


$KeyWord  = explode("\n", $RowGetWords['KEYWORDS']);
$Replace  = explode("\n", $RowGetWords['ReplaceTo']);

for($i=0; $i<count($KeyWord); $i++){
$pattern = $KeyWord[$i];
$replace = "<a href=\"" .$URL. "\" target=\"_blank\" >" .$Replace[$i]. "</a>";
$html = str_replace($pattern, $replace, $Row['MessageBody']);
}

so I use file_get_contents to get the contents of a webpage, one of the lines has


Code: [Select]
<meta property="og:url" content="http://www.google.com/blahblahblah?s=5cd04d4a7632296b9cdb463d04e82c05" />
I want it to echo only http://www.google.com/blahblahblah so anything between <meta property="og:url" content=" and ?s=5cd04d4a7632296b9cdb463d04e82c05" /> I want to extract and put into a variable

this works just fine but I was thinking preg match would be better


$thread = explode('<meta property="og:url" content="', $psuc);
$thread = explode('?s=', $thread[1]);
echo $thread[0];


Thanks

Hello,
I am trying to crawl a website and get all the domain names listed on the site to output into my php script. 
I am using the following code.... 
The main area is the preg match area, since I know nothing about it, nor do I understand it a little bit!

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://link I am getting data from.com);
curl_setopt($ch, CURLOPT_TIMEOUT, 30); //timeout after 30 seconds
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$result=curl_exec ($ch);
curl_close ($ch);
// Search The Results From The Starting Site
if( $result )
{
// LOOKING FOR ANYTHING.COM  all .com's
preg_match_all( "(.*)\.com", $result, $output, PREG_SET_ORDER );
 
foreach( $output as $item )

{
// ALL LINKS DISPLAY HERE 
print_r($item);



}

}


Any help would be greatly appreciated!
