replace string with a db function in php [duplicate]

Question

I want to replace a string with database function if it exists. I am using str_replace in following way but it doesn't work for me, this is returning $numOne as it was.

function stringreplace($multiple,$numOne){
    $multiple = Multiply;
    $numOne = a_b_cMultiply;
    str_replace($multiple, "abcdfgh('','')::numeric", $numOne);
    return $numOne;
}

Can you give us the before and after of the value you want to process? :) — L. Herrera

I can't seem to understand your code? What is Multiply? a_b_cMultiply? — L. Herrera

Multiply is a simple string and a_b_cMultiply is a formula. Actually i want if a_b_cMultiply comes it should be replaced by a_b_cabcdfgh('','') — Danish Bhatti

Your code is not correct as you are not storing the result anywhere and also you are returning $numOne which contains the old value . Use this code:

function stringreplace($multiple,$numOne){
$multiple='Multiply';
 $numOne='a_b_cMultiply';
 $num_one = str_replace($multiple,"abcdfgh('','')::numeric",$numOne);
return $num_one;
}

Well in that case change $numOne='a_b_cMultiply' to $numOne='a_b_c*Multiply'
