本文为大家讲解了一个php中strtok 函数的小技巧，感兴趣的同学可以参考下。

相对于explode()来说，strtok()函数可以控制节奏。按需切割字串。
其优点是：

1、可以一次定义多个分隔符。函数在执行时，是按单个分隔符来切割，而不是按整个分隔符，而explode则是按整个分隔串来切割的。正因此，explode可以用中文切割，而strtok则不行，会乱码。

2、在使用while或for配合strtok()遍历时，可以随时更换分隔符，也可以随时用break跳出终止切割。

示例1：演示用中文+explode来切割

$string = "这是PHP论坛论坛版块论坛栏目论坛H管理员论坛会员";
$arr = explode("论坛",$string);
foreach($arr as $v)
{
echo $v." ";
}
echo "------------- ";

这是PHP

版块
栏目
H管理员
会员
-------------

示例2：演示更换切割符，注意后面WHILE中不再带有“H”分隔符。而只是用空格。

$string = "这是PHP论坛论坛版块论坛栏目论坛H管理员论坛会员";
$tok = strtok($string, " H"); //空格+H
$n=1;
while ($tok !== false) {
echo "$tok ";
$tok = strtok(" "); //空格
//if($n>2)break; //可以随时跳出。
//$n++;
}
echo "------------- ";

这是P
P论坛
论坛版块
论坛栏目
论坛H管理员
论坛会员
-------------

示例3：演示多分隔符。

$string = "This istan examplenstring";
$tok = strtok($string, " nt"); #空格，换行，TAB
while ($tok !== false) {
echo "$tok ";
$tok = strtok(" nt");
}
echo "------------- ";

This
is
an
example
string
-------------

示例：

$string = "abcde 123c4 99sadbc99b5232";
$tok = strtok($string, "bc");
while ($tok !="") {
echo "$tok ";
$tok = strtok("bc");
}
echo "------------- ";

a
de 123
4 99sad
99
5232
-------------

示例4：演示用for来遍历：

$line = "leontatkinsontleon@test.com";
for($token = strtok($line,"t");$token!="";$token=strtok("t"))
{
print("token: $token n");
}

token: leon
token: atkinson
token: leon@test.com
