Output like this

$str = "this is a bet and he is Mansoon and he please search on <a href='http://www.google.com'>Google</a> and say he Yammy";

Many thanks

use this regex `[^<>]*<\/a>` and replace the match with empty string. — Avinash Raj, Nov 20 '14 at 09:02
@AvinashRaj - [^<>]*<\/a> this will not work if href= ""(having double quote) — Lalit Sharma, Nov 20 '14 at 09:05

try this: Update it may full fill all exception cases :

$re = "/(<a[^href]*href=[\"']{2}[^>]*>)([^<>]*|.*)(<\\/a>)/m";
$str = "this is a bet and he is <a id=\"sss\" href='' dfsd fdg >Mansoon</a> and he please search on <a href='http://www.google.com'>Google</a> and say he <a href=''>Yammy</a> \n<a href=''> <i>Yammy </i> <br/> </a>\n\nthis is a bet and he is Mansoon and he please search on <a href='http://www.google.com'>Google</a> and say he Yammy";
$subst = "$2";

$result = preg_replace($re, $subst, $str);

Except: `href='"` or `Yammy` or other html in the `href`. – Croises Nov 20 '14 at 13:12
`[^<>]*|.*` is the same as `.*` – Croises Nov 20 '14 at 15:21

<a[^>]*herf='*'[^>]*>[^>](.*?)<\/a> //works well even after space anywhere

This <a\h+href=(['"])\1>([^<>]*)<\/a> regex would match all the anchor tags which has an empty href value. Replacing the matched <a> tags with $2 will give you the desired output.

DEMO

<?php
$str = "this is a bet and he is <a href=''>Mansoon</a> and he please search on <a href='http://www.google.com'>Google</a> and say he <a href=''>Yammy</a>";
echo preg_replace('~<a\h+href=([\'"])\1>([^<>]*)<\/a>~', '$2', $str);
?>

Output:

this is a bet and he is Mansoon and he please search on <a href='http://www.google.com'>Google</a> and say he Yammy

\h+ matches one or more horizontal whitespace characters.

this will not work if there is a white space like sdfsfs – Lalit Sharma Nov 20 '14 at 09:13
now, it won't. Is there any possibility of one or more white space before `href` ? – Avinash Raj Nov 20 '14 at 09:14

You can use:

$str = "this is a bet and he is <a href=''>Mansoon</a> and he please search on <a href='http://www.google.com'>Google</a> and say he <a href=''>Yammy</a>";
$pattern = '/<a[^>]*?href=(?:\'\'|"")[^>]*?>(.*?)<\/a>/i';
$replacement = '$1';
echo preg_replace($pattern, $replacement, $str);
