php - How to replace a portion of string with a dot in regex? -

here string want replace:

<img src="./handler_image.php?i=c52bc1c30f560f4a15f99eeb8c04fea6" alt="favicon" class="favicon"> 

i wrote code:

$answer = preg_replace('/<img src="\./.*?>/', '', $answer); 

but not work. if replace with:

$answer = preg_replace('/<img src=".*?>/', '', $answer); 

it works replaces images , not ones src in format above. how should modify statement?

the forward slash after dot needs escaped too.

try this:

$answer = preg_replace('/<img src="\.\/.*?>/', '', $answer);
