Question

I am making a method to resize an image from wordpress.

I need to remove a value from a string eg:

<img src="/path/img.jpg" width="600" height="400" />

I need to remove the 600 and 400 values and place into my function like so:

resiseImg($width, $height);

I will then return the width and height and perform a str_replace. However I am unsure as to how I will actually take them out of the string, I guess an ugly way could be to perform some form of binary search algorithm of the string, which I really don’t want to do unless there is no other option.

Answer 1

php > $a = '<img src="blahh" width="600px" height="400px" />';
php > print preg_match_all('/[0-9]+/',$a,$res);
2
php > print_r($res);
Array
(
    [0] => Array
        (
            [0] => 600
            [1] => 400
        )
)
