I am programming in php and I have the following variable :
$calculation = '15-12';
Is there a function allowing me to convert the character string into calculation?
My Answer:
Yes, you can use the `eval()` function in PHP to evaluate a string as a mathematical expression. Here's how you can use it to convert the string into a calculation:
php
$calculation = '15-12';
$result = eval("return $calculation;");
echo $result; // Output: 3
Please note that using `eval()` can be risky as it can execute any PHP code within the string. Make sure to validate and sanitize the input before using `eval()` to prevent any security vulnerabilities.
