help - replacing adsense pid with

[prakash]

I need an reg expression code for replacing "google_ad_client" and "google_ad_channel"

 

<script type="text/javascript"><!--
google_ad_client = "pub-0000000000000000";
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "image";
google_ad_channel = "0000000000";
//-->
</script>
<script type="text/javascript"
  src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

 

thanks in advance

<script type="text/javascript"><!--
var google_ad_client = "pub-0000000000000000";
var string = "abc" + google_ad_client + "def";
alert(string.replace(google_ad_client, '123'));
//-->
</script>

 

This only works because google_ad_client does not have any metacharacters; if it did, you would get varying results. I'm not aware of any Javascript built-ins that properly quote a string being made into a pattern.

actually the above code and some other stuffs is stored into the variable.

can't we use "preg_replace" or "str_replace" using regex for that
