  • 0

Is there any way for all my PHP and/or HTML file output to be “filtered” before being displayed in the browser? I figured that I could pass it through a global function before it is displayed but I’m stuck on the implementation. Please help.

If there is a better way to achieve the same result, I’d be happy to know.

Thanks.

    Check out ob_start which lets you pass a callback handler for post-processing your script output.

    For example, PHP includes a built-in callback ob_gzhandler for use in compressing the output:

    <?php

ob_start("ob_gzhandler");

?>
<html>
<body>
<p>This should be a compressed page.</p>
</html>
<body>

    Here’s a fuller example illustrating how you might tidy your HTML with the tidy extension:

    function tidyhtml($input)
{
    $config = array(
           'indent'         => true,
           'output-xhtml'   => true,
           'wrap'           => 200);

    $tidy = new tidy;
    $tidy->parseString($input, $config, 'utf8');
    $tidy->cleanRepair();

    // Output
    return $tidy;
}

ob_start("tidyhtml");

//now output your ugly HTML

    If you wanted to ensure all your PHP scripts used the same filter without including it directly, check out the auto_prepend_file configuration directive.
