Use strlen(). For example:
$String = 'hi my name is';
if (strlen($String) > 20) {
$String = substr($String, 0, 17).'...';
}
In PHP4, you can use the substr_replace() function to replace the
third line in the example above:
$String = 'hi my name is';
if (strlen($String) > 20) {
$String = substr_replace($String, '...', 17);
}
For more information, see
