我有从JSON文件转换的数组。此数组中的数据是重复的。如何删除重复数据？
Array
(
[0] => Array
(
[code] => A
[children] => Array
(
[0] => Array
(
[code] => A-4
[children] => Array
(
[0] => Array
(
[code] => A-4-2
[children] => Array
(
)
[id] => 1224
[name] => ALTERNATOR
)
[1] => Array
(
[code] => A-4-3
[children] => Array
(
)
[id] => 1225
[name] => STARTER
)
[2] => Array
(
[code] => A-4-1
[children] => Array
(
)
[id] => 1223
[name] => IGNITION COIL & SPARK PLUG
)
[3] => Array
(
[code] => A-4-4
[children] => Array
(
)
[id] => 1226
[name] => VACUUM PUMP
)
[4] => Array
(
[code] => A-4-2
[children] => Array
(
)
[id] => 1224
[name] => ALTERNATOR
)
[5] => Array
(
[code] => A-4-3
[children] => Array
(
)
[id] => 1225
[name] => STARTER
)
[6] => Array
(
[code] => A-4-1
[children] => Array
(
)
[id] => 1223
[name] => IGNITION COIL & SPARK PLUG
)
[7] => Array
(
[code] => A-4-4
[children] => Array
(
)
[id] => 1226
[name] => VACUUM PUMP
)
)
[id] => 1183
[name] => Ignition
)
)
[id] => 1171
[name] => Engine/Cooling/Emission/Fuel
)
)
输出应该是这样的
Array
(
[0] => Array
(
[code] => A
[children] => Array
(
[0] => Array
(
[code] => A-4
[children] => Array
(
[0] => Array
(
[code] => A-4-2
[children] => Array
(
)
[id] => 1224
[name] => ALTERNATOR
)
[1] => Array
(
[code] => A-4-3
[children] => Array
(
)
[id] => 1225
[name] => STARTER
)
[2] => Array
(
[code] => A-4-1
[children] => Array
(
)
[id] => 1223
[name] => IGNITION COIL & SPARK PLUG
)
[3] => Array
(
[code] => A-4-4
[children] => Array
(
)
[id] => 1226
[name] => VACUUM PUMP
)
)
[id] => 1183
[name] => Ignition
)
)
[id] => 1171
[name] => Engine/Cooling/Emission/Fuel
)
)

使用 array_unique 解决您的问题：
$array['children'] = array_unique($array['children'], SORT_REGULAR);
// SORT_REGULAR means compare items normally (don't change types)
答案 1 :(得分：0)
我还没有测试过我的代码..试试这个： -
$array = //put the array in this variable
foreach($array as $mkey $arr){
foreach($arr['children'] as $skey => $arrchild){
$array[$mkey]['children'][$skey]['children'] = array_unique($arrchild['children']);
}
}
echo "<pre>"; print_r($array); die;
希望它有所帮助！
