对于一维数组去除重复值的方法,是可以直接使用php系统函数array_unique,但是这个函数不能对多维数组去除重复值。

下面分享一个可以去除二维数组的重复值的函数。

//二维数组去掉重复值

function array_unique_fb($array2D){  <br />	foreach ($array2D as $v){<br />		$v=join(',',$v);//降维,也可以用implode,将一维数组转换为用逗号连接的字符串<br />		$temp[]=$v;<br />	}<br />	$temp=array_unique($temp);//去掉重复的字符串,也就是重复的一维数组<br />	foreach ($temp as $k => $v){<br />		$temp[$k]=explode(',',$v);//再将拆开的数组重新组装<br />	}<br />	return $temp;<br />}
