[SOLVED] passing values to two variable

[black_box]

I want something like this

 

$a //query the table "Library" (but i want the value of $b)

//inserting data into table "Library" database

$b //after query "Library" table the output

 

So i want the value of b to the a (mean value of $b and $a is same) so how to pass the value of b to a?

You want $b to be the same as $a? Just write

 

$b = $a; // sets $b to whatever $a is
// or
$a = $b; // sets $a to whatever $b is
