二组数据分割成字符串以“，”隔开

php 数组 字符 Array
(
[0] => Array
(
[mobile] => 13814002394
)

[1] => Array
(
[mobile] => 13814002395
)

[2] => Array
(
[mobile] => 13814002396
)

[3] => Array
(
[mobile] => 13814002397
)

[4] => Array
(
[mobile] => 13814002398
)

[5] => Array
(
[mobile] => 13814002399
)

[6] => Array
(
[mobile] => 13814002400
)
）

这是得出的二组数组，我想分割成字符串 $mobile=13814002399,13814002400,13814002398;

这样只的形式

回复讨论(解决方案)

$mobile = join(',', array_map(function($v) { return current($v); }, $arr);

如果PHP版本在5.5还可用array_column()

还有没有答案！！！！！！！！！

$mobile=implode(',',array_map(function($arr){return implode(',',$arr);},$arr));

$array=array(	'0'=>array('mobile'=>'13814002394'),	'1'=>array('mobile'=>'13814002395'),       	'2'=>array('mobile'=>'13814002396'),	'3'=>array('mobile'=>'13814002397'),	'4'=>array('mobile'=>'13814002398'),	'5'=>array('mobile'=>'13814002399'),	'6'=>array('mobile'=>'13814002400'));foreach($array as $key=>$value){	$mobile.=$dot.$value['mobile'];	$dot=",";}return $mobile;

$array=array(	'0'=>array('mobile'=>'13814002394'),	'1'=>array('mobile'=>'13814002395'),       	'2'=>array('mobile'=>'13814002396'),	'3'=>array('mobile'=>'13814002397'),	'4'=>array('mobile'=>'13814002398'),	'5'=>array('mobile'=>'13814002399'),	'6'=>array('mobile'=>'13814002400'));foreach($array as $key=>$value){	$newarray[$key]=$value['mobile'];}return join(",",$newarray);
