Any preg_match () for extracting image urls from text?

Question

I need syntax or something similar to extracting JPG or PNG or GIF URLs from blended text and putting them in an array or finally storing the first URL. preg_match()

there may be some syntax that looks for lines starting with http and ending with jpg / png / gif ..

I believe this can be done with preg_match()

Note: the text may be like this: blablablabla " http://www.example.com/xxx.jpg " blablablabla

Answer 2

$matches = array();
preg_match_all('!http://.+\.(?:jpe?g|png|gif)!Ui' , $string , $matches);

Answer 3

The update for the case is the http / https optional prefix, for example:

http://example.com/image.jpg

https://example.com/image.jpg

//example.com/image.jpg




            function extractImageUrlFromText($text)
            {
                preg_match_all('!(https?:)?//\S+\.(?:jpe?g|jpg|png|gif)!Ui', $text, $matches);
                return $$matches[0];
            }
