Question

Is this possible?

Like make an array with all the variables that have a certain prefix?

I don’t need the keys just the values, but I guess I could use array_values on the array.

If you need to do this, it’s probably not written very well to begin with, but, here’s how to do it 🙂

$foobar = 'test';
$anothervar = 'anothertest';
$foooverflow = 'fo';
$barfoo = 'foobar';

$prefix = 'foo';
$output = array();
$vars = get_defined_vars();
foreach ($vars as $key => $value) {
    if (strpos($key, $prefix) === 0) $output[] = $value;
}

/*
$output = array(
    'test', // from $foobar
    'fo', // from $foooverflow
);
*/
