求大神指导，我想把数组相同的值合并，原本是这样的
array(5) {
[0] => array(1) {
["id"] => string(1) "2"
}
[1] => array(1) {
["id"] => string(1) "2"
}
[2] => array(1) {
["id"] => string(1) "1"
}
[3] => array(1) {
["id"] => string(1) "1"
}
}
我想要的效果是以下这样的
array(5) {
[0] => array(1) {
["id"] => string(1) "1"
}
[1] => array(1) {
["id"] => string(1) "2"
}
}
$ar = array ( 0 => array ( "id" => "2" ), 1 => array ( "id" => "2" ), 2 => array ( "id" => "1" ), 3 => array ( "id" => "1" ),);$arr = array();foreach($ar as $v){ if(!isset($arr[$v['id']])) $arr[$v['id']] = $v;}ksort($arr);print_r(array_values($arr));
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移，垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是，许多工具可以让 Windows 保持平稳运行。
