php字符串分割函数使用示范

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
)
