PHP - Replacing Ereg_replace And Eregi_replace With Preg_replace

I am interested in just this little snippet of code I am writing for a basic TCP socket server in PHP.

Just basically goes along the lines of this:
Code: [Select]
<?php
$value = ereg_replace("\n\t\r", "", trim($input)).chr();

It's actually regarding the chr() I know actually its nothing to do with the regular expression replace but what does it actually mean to PHP?

I mean I am just using it as an output from a socket_read (as that's what $input is assigned to the value of), but what does the char(0) mean?

I mean I seem to remember it being knowing the end of a line of data once the clients sent data into the stream PHP looks at chr(0) as the end of the line of data is that the right way of thinking about this logically?

Any helps appreciated, trying to explain such a topic on my blog and I am confused about what to say about that one little bit, I know it's not really part of the regular expression but what does it actually do?

Again massive thanks in advance for any replies,
Jeremy.

Hello all,

I need to switch my code from ereg_replace to preg_match but I'm having trouble figuring out how to get the syntax right for this and keep the same functionality.

$vendor_ID = ereg_replace("^\*","",$key);

Any advice on how to maintain this functionality but use non-deprecated methods?

Can anyone help me with this - I don't normally do coding.   I've just moved an old site onto new hosting and I'm getting this message: Deprecated: Function ereg_replace() is deprecated    The code looks like this: if( preg_match( '/sl/i', $sOption ) )     $sContent = addslashes( $sContent );   else     $sContent = stripslashes( $sContent );     $sContent = ereg_replace( "\r", '', $sContent );     if( preg_match( '/len/i', $sOption ) )     $sContent = checkLengthOfTxt( $sContent );   I changed it to look like this: if( preg_match( '/sl/i', $sOption ) )     $sContent = addslashes( $sContent );   else     $sContent = stripslashes( $sContent );     $sContent = preg_replace( "\r", '', $sContent );     if( preg_match( '/len/i', $sOption ) )     $sContent = checkLengthOfTxt( $sContent );   But now get this warning message: Warning: preg_replace() [function.preg-replace]: Empty regular expression    I didn't build the site so I don't even know what the script is trying to do - forgive my ignorance!

How to solve this error out

PHP Deprecated: Function ereg_replace() is deprecated in

using this code

Code: [Select]
$shoutcast_on_off ='';
$scsuccs = '';

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']));
}

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?

Hi everyone,

how do i add and ampersand symbol into preg_replace

preg_replace("/[^a-zA-Z0-9\s\-\'\,\.\_]/"

where do i place the symbol? &

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 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!

Hello ppl,
I have this website link http://www.somesite.com/anotherpage/yetotherpage.html what i want to make is using preg_replace that the final result will be www.somesite.com

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 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.

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
