php合并数组中相同元素的方法,php合并数组元素
本文实例讲述了php合并数组中相同元素的方法。分享给大家供大家参考。具体如下:
关于重复数组的删除我们都介绍过N种方法了,今天这个例子有点不同就是 删除数组中相同的元素,只保留一个相同元素,具体实例代码如下:
复制代码 代码如下:
// 删除数组中相同元素,只保留一个相同元素
function formatArray($array)
{
sort($array);
$tem = "";
$temarray = array();
$j = 0;
for($i=0;$i
if($array[$i]!=$tem)
{
$temarray[$j] = $array[$i];
$j++;
}
$tem = $array[$i];
}
return $temarray;
}
//测试 调用函数
$array = array('aa','bb','aa',3,4,5,5,5,5,'bc');
$arr = formatArray($array);
print_r($arr);
?>
希望本文所述对大家的php程序设计有所帮助。
