我有两个数组.
检查代码
$array1 = array(0=>'215',1=> '225');
$array2 = array(0=>'225');
$diff_result = array_diff($array1, $array2);
$diff = array_values($diff_result);
print_r($array1);echo "<br>";
print_r($array2);echo "<br>";
print_r($diff_result);echo "<br>";
print_r($diff);
现在我得到了答案
Array ( [0] => 215 [1] => 225 )
Array ( [0] => 225 )
Array ( [0] => 215 [1] => 225 )
Array ( [0] => 215 [1] => 225 )
但根据array_diff手册应该是
Array ( [0] => 215 [1] => 225 )
Array ( [0] => 225 )
Array ( [0] => 215 )
Array ( [0] => 215 )
可能是什么问题呢
最佳答案 我按原样运行你的代码,我得到了正确的结果.
$array1 = array(0=>'215',1=> '225');
$array2 = array(0=>'225');
$result = array_diff($array1, $array2);
$diff_result = array_diff($array1, $array2);
$diff = array_values($diff_result);
print_r($array1);echo "<br>";
print_r($array2);echo "<br>";
print_r($diff_result);echo "<br>";
print_r($diff);
输出:
Array ( [0] => 215 [1] => 225 )
Array ( [0] => 225 )
Array ( [0] => 215 )
Array ( [0] => 215 )
