replace string with a db function in php

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. i am beginner in php so help me

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, Dec 01 '16 at 06:40
I can't seem to understand your code? What is Multiply? a_b_cMultiply? — L. Herrera, Dec 01 '16 at 06:45
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, Dec 01 '16 at 06:48

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'` – Rahul Dec 01 '16 at 06:56
