Help me regarding preg_replace

[jhbalaji]

Hello everyone i am writing a snippet for replacing the keywords into links.

It almost works but it also replaces the words in between HTML Tags

So can anyone help me in fixing that

 

<?php
$textlinksname = 'Google';
$textlinksurl = 'http://google.com';
$body = 'Google is a great search engine. Here is the logo of it <img src =\'http://www.google.co.in/google/images/srpr/logo1w.png\'/>';

$replace = "<a href='".$textlinksurl."' target='_blank'>".$textlinksname."</a>";
$body = preg_replace('~(?<!http://|www\.|/)'.$textlinksname.'~i', $replace,$body,200);

echo $body;
?>

 

 

It outputs as

<a href='http://google.com' target='_blank'>Google</a> is a great search engine. Here is the logo of it
<img src ='http://www.google.co.in/google/intl/en_com/images/srpr/google-123-<a href='http://google.com' target='_blank'>Google</a>.png'/>

 

But i need output like this such that it wont mess with HTML Tags

 

<a href='http://google.com' target='_blank'>Google</a> is a great search engine. Here is the logo of it
<img src ='http://www.google.co.in/google/intl/en_com/images/srpr/google-123-Google.png'/>

 

 

Can anyone help me on how to prevent that???

 

Thanks in advance

Any Replies please

Your regular expression should be more specific about what (where) it will match so that if the URL appears within an anchor tag, the match is not successful.  This sub-forum has lots of threads trying to do precisely that.

In simple words

It should replace the keyword i specified into links but whenever it founds HTML Tags say Anchor Tag or Image Tag it should skip the Word in between those tags

 

can also be defined as

i need a regex pattern in which it should turn the keywords into links in a Paragraph without messing inbetween HTML Tgas

 

Thanks for your Help salathe

Have you had a look around the forums here? There are loads of threads asking about ignoring stuff within a tag.

try

$body = preg_replace('~(^| )'.$textlinksname.'\b~i', $replace,$body,200);

Tried that!

Some what works

 

Basically if a Image URL has a form of Space the it also replaces that!

 

But it temporarily fixes my problem

 

Thanks Again!
