//假如 数据是这样的
$arr=[
[
'goods_name'=>'xxx',
'goods_id'=>111,
],
[
'goods_name'=>'xxx',
'goods_id'=>123,
],
[
'goods_name'=>'xxx',
'goods_id'=>'123'
],
];
function array_unset_tt($arr,$key='goods_id'){
//建立一个目标数组
$res = array();
foreach ($arr as $value) {
//查看有没有重复项
if(isset($res[$value[$key]])){
unset($value[$key]); //有:销毁
}else{
$res[$value[$key]] = $value;
}
}
return $res;
}
//调用方法处理后,就把重复的goods_id的数组过滤,只剩下一个!!!开心吗?
