>我有一个数组
Array
(
[fbid] = Array
(
**[0] => 115637705237540
[1] => 115637705237540**
[2] => 111723238962320
[3] => 111723248962319
[4] => 112721842195793
[5] => 112567698877874
[6] => 111844022283575
**[7] => 115637705237540**
[8] => 111840252283952
[9] => 109642909170353
)
[fb_parentid] = Array
(
[0] => 571228125
[1] => 571228125
[2] => 571228125
[3] => 571228125
[4] => 571228125
[5] => 571228125
[6] => 571228125
[7] => 571228125
[8] => 571228125
[9] => 571228125
)
)
这里的 0、1 和 7 是重复的。首先，我想获取重复索引 （0,1,7）。其次，我想显示一个一索引。在上面的例子中只有第 0 个。
之后我想从 [fb_parentid] 和 [fbid] 中删除 1 和 7
你可以帮我吗？
您正在寻找array_unique函数。
$new_array = array_unique($old_array);
尝试
$array = Array
(
"fbid" => Array
(
"0" => 115637705237540,
"1" => 115637705237540,
"2" => 111723238962320,
"3" => 111723248962319,
"4" => 112721842195793,
"5" => 112567698877874,
"6" => 111844022283575,
"7" => 115637705237540,
"8" => 111840252283952,
"9" => 109642909170353
),
"fb_parentid" => Array
(
"0" => 571228125,
"1" => 571228125,
"2" => 571228125,
"3" => 571228125,
"4" => 571228125,
"5" => 571228125,
"6" => 571228125,
"7" => 571228125,
"8" => 571228125,
"9" => 571228125
)
);
$unique = array_unique($array["fbid"]);
$diffrence = array_diff_assoc($array["fbid"], $unique) ; // Return the difference
var_dump($diffrence);
$unique = array_unique($array["fb_parentid"]); // Get Unique Values
var_dump($unique);
输出
array
1 => float 1.1563770523754E+14
7 => float 1.1563770523754E+14
array
0 => int 571228125
