本文实例分析了php中explode函数用法。分享给大家供大家参考。具体如下:

explode(string separator,string string [,int limit])

separator 为空字符串(""),explode() 将返回 FALSE,如果 separator 所包含的值在 string 中找不到,那么 explode() 将返回包含 string 单个元素的数组.

explode实例一,代码如下:

代码如下:

$explode = "aaa,bbb,ccc,ddd,explode,jjjj";
 
$array = explode( ',' ,$explode );
 
print_r($array);
/*
//结果为
Array
(
    [0] => aaa
    [1] => bbb
    [2] => ccc
    [3] => ddd
    [4] => explode
    [5] => jjjj
)
*/


我们在处理日期或取得文件扩展名时就可以用explode函数与end函数操作,下面来看实例,代码如下:

代码如下:

$file ="www.bitsCN.com.gif";
 
 $extArray = explode( '.' ,$file );
 $ext = end($extArray);
 echo $ext;
 
//输出值为.gif


使用些函数出现的错误提示有:Note: Separator cannot be an empty string.注意:分割符不可以是空字符串,要分割的字符串为空.

Definition and Usage 未使用分割函数,可能是你设置的分割字符不存在.

希望本文所述对大家的PHP程序设计有所帮助。
