Hello Peeps

I am not good at all with preg_replace and would hopefully someone can advice.

How can I strip out a img tag and just get it's alt value ie.

Replace this:

<img src="/img/image.gif" alt="This Image" />

with this

"This Image"

I hope this makes sense.

hope you can advise.

thanks in advanced if you can.

Thanks for the reply but I cant get it to work.

Here is my exmaple of yours.

$1 = '<img src="/img/test.gif" alt="m test" />';

echo preg_replace('/<img .*?\salt="([^"]+)"[^>]*>/i', '$1');

Am I doing it wrong ?

Thanks Again

$text = '<img src="/img/test.gif" alt="m test" />';
echo preg_replace('/<img .*?\salt="([^"]+)"[^>]*>/i', '$1', $text);

by way of explanation, the '$1' is a reference to the first (in this case only) ()'d bit inside the pattern. The manual page (http://php.net/preg-replace) has more, see the bit on 'replacement' and the first example.

Just so it makes it easier to see.

Hope you can advice.

Thank you very much.
