Regular Expression ...

[dannymm]

Can some body tell me what's the equivalent regular expression for perl's word bound in PHP .. i,e
$result = preg_replace("/\b$myword\b/i","$hyperlinkstart $myword $hyperlinkend",$contents);

i,e to replace by word bound .... (i want to use eregi_replace instead of preg_replace)

i tried all options, even putting ^ and $ at the beginning and at the end respectively .. but it never matched ...

e.g my string is ... xyz company produces C product.

my script should hyperlink the product C ... but by using eregi_replace it even hyperlinks the c present in company ...

This is urgent ... and i do not want to use preg_replace ....

Thanks in advance,
Danny Appaiah ...

Just give it some space...
<?
$word = 'xyz company produces C product';
$linkText = 'C';
$hyperlinkstart = '<a href="mypage.php">';
$hyperlinkend = '</a>';

$result = eregi_replace(' ('.$linkText.') ',' '.$hyperlinkstart.'\1'.$hyperlinkend.' ',$word);
echo $result;
?>

BTW preg is far more powerful than ereg and faster as well. Don't know what you have against it, but ereg blows in my book.
Try matching '<>' in ereg matches '~' as well.
Ok if you want to regex for math terms that may mean the same thing... but for patterns on strings that is a serious error.
And being that regex is for string patterns, I'd say ereg has some serious flaws.

Thanks for the inputs Van ..
I am not against preg ... but some of the service providers do not have perl compatible regular expression feature by default, where as ereg comes by default. so i do not want to take risk and end up changing all the code when this issue crops up.
