最近工作中碰到一个问题,用PHP将一个二维数组按照二维数组中的各个项中的某个特定字段值合并成一维数组,如果有重复则将重复的合并成二维数组,生成的二维数组的第一维的键是特定字段的值,二维的键可以是随机索引,也可以是其中的另一个字段的值。其实这个需求经常会在工作中碰到,只是碰到的时候一个有重复的就直接用之前的覆盖后面的或者用之后的覆盖之前的,这样很容易就可以处理了。很少碰到这种有一维数组又有二维数组的情况,先上代码:

$a = array(  
    0 => array(‘target_id‘ => ‘22‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘15261‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    1 => array(‘target_id‘ => ‘22‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘2‘, ‘extension_number‘ => ‘66002‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => ‘1‘,),  
    14 => array(‘target_id‘ => ‘22‘, ‘target_type‘ => ‘1‘,‘phone_type‘ => ‘4‘, ‘extension_number‘ => ‘56431‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    2 => array(‘target_id‘ => ‘24‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘54876‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => ‘1‘,),  
    3 => array(‘target_id‘ => ‘25‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘07143‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    13 => array(‘target_id‘ => ‘24‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘0‘, ‘extension_number‘ => ‘96949‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    4 => array(‘target_id‘ => ‘26‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘94755‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    5 => array(‘target_id‘ => ‘30‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘14171‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    6 => array(‘target_id‘ => ‘36‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘54876‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => ‘1‘,),  
    7 => array(‘target_id‘ => ‘42‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘31354‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    8 => array(‘target_id‘ => ‘43‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘66810‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    9 => array(‘target_id‘ => ‘45‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘34868‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    10 => array(‘target_id‘ => ‘50‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘79523‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    11 => array(‘target_id‘ => ‘149‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘59438‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    12 => array(‘target_id‘ => ‘806‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘14780‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
);  
$target = array();  
$temp = array();  
foreach ($a as $val) {  
    if (!empty($target)) {  
        if (in_array($val[‘target_id‘], array_keys($target))) {  
            if (!empty($temp[$val[‘target_id‘]])) {  
                $target[$val[‘target_id‘]] = null;  
                $target[$val[‘target_id‘]][$temp[$val[‘target_id‘]][‘phone_type‘]] = $temp[$val[‘target_id‘]];  
                $temp[$val[‘target_id‘]] = null;  
            }  
            $target[$val[‘target_id‘]][$val[‘phone_type‘]] = $val;  
        } else {  
            $temp[$val[‘target_id‘]] = $val;  
            $target[$val[‘target_id‘]] = $val;  
        }  
    } else {  
        $temp[$val[‘target_id‘]] = $val;  
        $target[$val[‘target_id‘]] = $val;  
    }  
}  
var_dump($target);exit;  
这个返回的结果形如:

  如果不想要生成的二维数组的key值,或者说再精简些,可以这样:

$a = array(  
    0 => array(‘target_id‘ => ‘22‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘15261‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    1 => array(‘target_id‘ => ‘22‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘2‘, ‘extension_number‘ => ‘66002‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => ‘1‘,),  
    14 => array(‘target_id‘ => ‘22‘, ‘target_type‘ => ‘1‘,‘phone_type‘ => ‘4‘, ‘extension_number‘ => ‘56431‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),

    7 => array(‘target_id‘ => ‘42‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘31354‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),  
    8 => array(‘target_id‘ => ‘43‘, ‘target_type‘ => ‘1‘, ‘phone_type‘ => ‘1‘, ‘extension_number‘ => ‘66810‘, ‘phone_id‘ => ‘1‘, ‘phone_number‘ => ‘4008285599‘, ‘extension_special‘ => NULL,),

$target = array();
