Split the two groups of data into strings separated by "," (& nbsp; [0] & nbsp ;=& gt; & nbsp; array & nbsp; (separate two groups of data into strings by commas (,)
Array
(
[0] => Array
(
[Mobile] = & gt; 13814002394
)

[1] => Array
(
[Mobile] = & gt; 13814002395
)

[2] => Array
(
[Mobile] = & gt; 13814002396
)

[3] => Array
(
[Mobile] = & gt; 13814002397
)

[4] => Array
(
[Mobile] = & gt; 13814002398
)

[5] => Array
(
[Mobile] = & gt; 13814002399
)

[6] => Array
(
[Mobile] = & gt; 13814002400
)
)

This is a two-group array. I want to split it into strings $ mobile = 13814002399,13814002400, 13814002398;

In this way, only php array characters are shared :? Array ???????? (???????????? [Mobile]? =>? 13814002394 ????????)???? [1]? =>? A... 'data-pics = ''>
