放弃多个/重复的br标签

I want to remove multiple <br> tags which are repeated more than 2times, for example:

This is text blah blah...
<br><br><br><br><br><br>Another text here

Should be:

This is text blah blah...
<br><br>Another text here

I have this:

$str = preg_replace('#(<br\s?/?>)+#', '<br><br>', $str );

But this also replace simple <br> tags with 2 brs, how I could change the regular expression for this?

Thanks

Try this one..

#(<br\s?/?>){2,}#

Codepad.

If your <br>s include spaces in between then this follow this one -

#(<br\s?/?>\s*){2,}#

Codepad

Try this:

$str = 'This is text blah blah...
<br><br><br><br><br><br>Another text here';

echo preg_replace('#(\s*<br\s*/?>\s*<br\s*/?>\s*)+#', '<br><br>', $str );

Output:

This is text blah blah...
<br><br>Another text here

DEMO

Update: Thanks for @M42 for his point:

echo preg_replace('#(\s*<br\s*/?>\s*){2,}#', '<br><br>', $str );
