PHP - Replace string src value with data uri

Question

Good day.

I have an array which holds the data uri of an img.

$var =
array(
[0] => data:image/png;base64,iVBORw0KGgoAA...
[1] => data:image/png;base64,Rw0KKGgoasWAA...
);

And I have a string.

$foo = '<p>test 7/31/2</p> <p>&nbsp;<img src="/media/1.png" alt="" /></p> <p><img src="/media/2.png" alt="" /></p>';

How can I replace the src in $foo with the data uri array in $var?

Result would be like.

$foo = '<p>test 7/31/2</p> <p>&nbsp;<img src="data:image/png;base64,iVBORw0KGgoAA..." alt="" /></p> <p><img src="data:image/png;base64,Rw0KKGgoasWAA..." alt="" /></p>';

Any ideas will do!

Answer 1

Try this:

$images = [
    "/media/1.png" => 'data:image/png;base64,iVBORw0KGgoAA...',
    "/media/2.png" => 'data:image/png;base64,Rw0KKGgoasWAA...'
];

$url = '<p>test 7/31/2</p> <p>&nbsp;<img src="/media/1.png" alt="" /></p> <p><img src="/media/2.png" alt="" /></p>';
$url = str_replace(array_keys($images), array_values($images), $url);
