    PHP Tutorial 017: Strings, SubStrings and String positions

    PHP Tutorials

    If the title confuses you, don’t fret. My tutorial will explain it to you. Strings, as we know in compu-speak is text. Well, if you want to get part of the text but not all of it, you can use substring. Then if you want to find the position of some text to use in the substring function , you can use the function for that to find the matches for what you put in. However, if there is no match it will default to 0.
    You need flash to play this tutorial.
    This tutorial goes over the following goals:
    Parts of strings
    Positions in Strings
    String lengths once more
    You can find this tutorial video on youtube here.

    Here are the sources used in this tutorial:
    tut017.php
    <?php
//PHP Tutorial 017

$string = "We eat lots of bread and butter all day long with tacos!";
$search = "bread";
$pos = strpos($string, $search);

$return = substr($string, $pos+strlen($search));

echo $return;
?>

    Here are all the php functions used in this tutorial:
