本文實(shí)例講述了php比較兩個(gè)字符串長(zhǎng)度的方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：

這段代碼計(jì)算兩個(gè)字符串的長(zhǎng)度，然后計(jì)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");

?>

希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。
