php数组中需要对数组按首字符过滤,通过下面的代码实现了,需要的朋友可以参考下
复制代码 代码如下:
$array = array(
'abcd',
'abcde',
'bcde',
'cdef',
'defg',
'defgh'
);
$str = '~'.implode('~',$array).'~';
$word = $_GET['word']; //url = xxx.php?word=a
preg_match_all("/~({$word}(?:[^~]*))/i",$str,$matches);
var_dump($matches[1]);
//输出
//array(2) { [0]=> string(4) "abcd" [1]=> string(5) "abcde" }
//End_php
另:这段代码发现了一个奇怪的问题:分隔符使用','(逗号)的时候会出现问题。
