php中 explode 和 split 函数用来分割字符串。
explode函数语法如下
explode(substring, string)
explode函数通过子字符串进行分割,效率比split要高
split函数语法如下
split(pattern, string)
split通过正则表达式对字符串进行分割,效率相对explode要低,但是功能强大
<?php $list = explode("_","php_strting_function.html"); print("explode() returns:\n"); print_r($list); $list = split("[_.]","php_strting_function.html"); print("split() returns:\n"); print_r($list); ?>
输出结果如下
explode() returns: Array ( [0] => php [1] => strting [2] => function.html ) split() returns: Array ( [0] => php [1] => strting [2] => function [3] => html )
