PHP - Need to calculate the string formula to integer value [duplicate]

Question

I need to convert the formula like string to its calculated value, in PHP.

For eg:

$str = "(20000+(2000*(40/100)))*(10/100)";
$calculated_value = ????; // Calculated value of the above string "$str".

I need to calculate value of the string "$str" and store it in separate string. Please help me out.

Thanks in advance.

If someone suggests using a function starting with an e and ending on al, then ignore that. You need to parse this string (possibly using a stack-based approach). Fun! — Lekensteyn
