Php find and replace.. DOM?

[The_Test_Guy]

Hi there,

I want to run a script at the begining of each page that picks up all <img> tags and changes the href attribute in them on the fly as the server runs it...

I know there is a complicated DOM method that we can use in JS to do this. I was wondering if there is any php function.

Thank you for your time.

Hi!
I think it`s the 'src' attribute in the image tag you want to change.

A possible solution, but maybe not the best, is to buffering the output.

// First in the script.
ob_start();

//Include the html.
include('myHtml.html');

// Read the output into a string and clean the buffer.
$output = ob_get_contents();
ob_end_clean();

// The new image directory
$newImageDir = 'newDir';

// Replace the stuff.
$output = str_replace('<img src="oldImgDir', '<img src="'.$newImageDir, $output);

echo $output;

The best way is probaly to change your image directory structure so this isnt needed.

Why not just remove the image tags from the HTML document and insert bits of PHP code there? You could link them all to a parent function....
