break up a string into integers

[android6011]

Ok, I have a variable named length, the variable outputs something such as 4:06 . What I want to do is have the page refresh after that length, but the meta tag needs seconds. I know how to do the math portion of it, im just not sure how to break it up so I can get the 4 and the 06 separate. thanks

Use the explode() funciton:

<?php
$str = '4:06';
list ($min,$sec) = explode(':',$str);
$secs = ($min * 60) + $sec;
echo $secs;
?>

I think kenrbnsn has the best solution, but if you ever have a string where you have a number of integers, and you simply want to extract them all, you could do something like this, and you wouldn't have to worry about what the separators were:

<?php
if (preg_match_all('|\d+|', $string, $matches)) {
  foreach ($matches[0] as $x) {
    echo "Found $x<br />\n";
  }
}
?>
