在MySQL数据库中插入一个数组

Question

I want to insert an array into my MySQL database in the format a,b,c.

 `var_dump($pvt_contacts)`

results

array(1) { [0]=> array(2) { [0]=> string(3) "102" [1]=> string(1) "3" } } 

I tried

`implode(',',$pvt_contacts)' 

but it echos Array not 102,3 as I expected . Please help me

Answer 1

If you just want 102,3, then you're off by one (your pointing to a parent array, and not the elements):

implode(',',$pvt_contacts[0]);

• If you're trying to store an array in a DB, I recommend serialize. (despite its prevalence in Drupal, ExpressionEngine, Wordpress, etc. this is not generally the best idea).
• If you're trying to sent an array to js, I recommend json_encode.
• If you're doing something else I need more information.
