二组数据分割成字符串以“,”隔开
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
