add string after img with php

I need to add a string (in this case is a div) after an img tag on each post on wordpress. I know where do it but I don't know how. I tried with preg_replace but it doesn't work:

$content = preg_replace('/<img[^>]+\>/i', '/<img[^>]+\>/i <div...>', $content);

As result i get /<img[^>]+\>/i <div...> and not the img followed by . How can I do?

The second argument to preg_replace() should be the replacement string, not another regular expression. You can use $0 (the whole match) or $1 ~ $9 for each of the memory captures you have. In your case you don't have any memory captures (stuff between parentheses), so:

$content = preg_replace('/<img[^>]+>/i', '$0 <div...>', $content);

Btw, you don't have to escape the > in the expression.

The replace part should be: '$0 <div...>', which basically sais: take what you have found with my pattern and append my div.

So your code should like:

$content = preg_replace('/<img[^>]+\>/i', '$0 <div...>', $content);

$content = "<img /> <br/> <img />" ;
$content = preg_replace('/(<img[^>]+\>)/i', '$1 <div></div>', $content);
echo htmlentities($content) ;
