Question

I have a data in My-Sql column like this

T_interest
1,14,49,145,203,302

It represents each value for personal interest keywords.

I tried to extract the value and distinguish whether it has the value or not for the checkbox.

if(strstr($u_interest['u_interest'], ','.$row['i_idx'])):
$selected = 'checked';

here is the php command that I use right now.

but it doesn’t extract exact value from the database.

Let’s say I want to check if the data has 14 number or from this user table

T_interest
1,14,49,145,203,302

and if I use above command it tells me that a user has two values.

14,145 

It looks like PHP strstr command tells me two values because these two have 14 number.

So, can you help me why this is happening?

If you want more php lines I can post them.

Answer 1

Explode it into an array, this way you get the individual values.

explode(",",$t_interest["u_interest"]);

Then you can test for equality much easier.
