这段代码计算两个字符串的长度，然后计算其差值
<?php
// This will return a number of how many more characters the longest string has
function str_compare_length($str1, $str2){
$len1 = strlen($str1);
$len2 = strlen($str2);
return abs($len1 - $len2);
}
echo str_compare_length("This is the first string", "This is the second string");
?>
