Help With Preg_replace And Ereg_replace

[adex3g]

$AOG_te = ereg_replace("http://[A-Za-z0-9./=?-_]+","<a href="\\0">\\0</a>", $AOG_te);
$AOG_te = preg_replace("/\[url\=(.*?)\](.*?)\[\/url\]/is","<a href="$1">$2</a>",$AOG_te);
i have that above code in my bbcode function.
But ereg_replace did not allow the preg_replace to work, what can i do so that two will work without affecting each other.
If user post http:// coding-talk.com or [ url=http:// coding-talk.com]coding-talk[/url] should turn to link.

the problem arises when using double quotes. Try using single quotes.

[NOTE]: function ereg_replace() is deprecated as of PHP 5.3.0.

$AOG_te = ereg_replace('http://[A-Za-z0-9./=?-_]+','<a href="$1">$2</a>',$AOG_te);
$AOG_te = preg_replace('/\[url\=(.*?)\](.*?)\[\/url\]/is','<a href="$1">$2</a>',$AOG_te);

not working, it return [url=$2

Try this:

$URLSearchString = " a-zA-Z0-9\:\&\/\-\?\.\=\_\~\#\'";  
$AOG_te = preg_replace("(\[url\]([$URLSearchString]*)\[/url\])is", '<a href="$1">$1</a>', $AOG_te);
$AOG_te = preg_replace("(\[url\=([$URLSearchString]*)\]([$URLSearchString]*)\[/url\])is", '<a href="$1" >$2</a>', $AOG_te);
