二维数组中怎么除去重复项呢
我有个array,var_dump出来的值是:
array(1) { [0]=> array(3) { [0]=> string(0) "" [1]=> string(4) "古牧" [2]=> string(0) "" } }
现在要给这个数组新增值:$info[] = $insert;
新增完了之后,我想去除掉重复的项 不希望同样的项有两条
我用array_unique($info)不管用呢 请问怎么去重呢?
就是如果还有个项是{"","古牧",""}

就只要一项 或者新增的时候就判断

------解决方案--------------------

PHP code
function array_multiunique($ar) {
  $t = array_map('serialize', $ar);
  $t = array_unique($t);
  return array_map('unserialize', $t);
}   

$ar = array(
  array("","古牧",""),
  array("","古牧",""),
);

print_r(array_multiunique($ar)); <div class="clear">
                 
              
              
        
            </div>
