    You may be looking for something more like this:
    <?php
$subject = "GreenWithEnvy15";
preg_match_all('/[0-9]/', $subject, $matches);
$count = count($matches[0]);
echo $count; //echos number of integers in $subject
?>
    PHP:

    Hi,

    if you want get / print the value of numbers , you can use this code in the bottom of the "GreenWithEnvy" code

    for ($i = 0 ; $i < $count ; $i++ )
    {
    echo $matches[0][$i];
    echo '<br/>';

    }

    preg_replace("/[^0-9]/","",$string);
