二位数组多字段去重
不指定一个字段去重，判断所有字段是否有重复
$arr = [
0 => [
‘name‘ => ‘name1‘,
‘age‘ => ‘10‘
],
1 => [
‘name‘ => ‘name1‘,
‘age‘ => ‘11‘
],
2 => [
‘name‘ => ‘name2‘,
‘age‘ => ‘10‘
],
3 => [
‘name‘ => ‘name2‘,
‘age‘ => ‘10‘
]
];
方法:
$res = []; foreach ($arr as $key => $value) { //重新排序value ksort($value); //获取key ，判断是否存在的依据 $key = implode("_", $value); //name1_10 //md5 为了防止字段内容过长特殊字符等 $res[md5($key)] = $value; } //重置索引 $res = array_values($res); var_dump($res);
