Question

I have a script that will insert a value in a cell, in my database. That cell will contain 4 values total. It should look like this: 0;0;0;0 (Each ‘0’, represents a value)

How can I insert example value 100, at the place where ‘0’ number 3 is, so it will look like this:

0;0;100;0

Thanks in advance.

Answer 1

look into serialize() and unserialize()

$array = array(0,20,103,330);
$string = serialize($array); // store this in db

then get the string from db:

$array = unserialize($string);

access/update values with the array and re-store in db

Or if you are stuck with the format:

$string = '0;0;100;0'; // coming from db
$array = explode(';' , $string);
$array[2] = 100;
$string = implode(';' , $array);
