How Can I Safely Handle Division by Zero Errors in PHP?

Catching Division by Zero Errors in PHP

When working with dynamic mathematical expressions, catching division by zero errors can be crucial to prevent application crashes. While using the eval function, attempts to handle the error with try/catch blocks may not work as expected.

To resolve this issue, you can leverage the enhanced error handling introduced in PHP7. Division by zero now throws a dedicated DivisionByZeroError exception. Here's how you can implement it:

try {
    eval("$result = $expresion;");
} catch(DivisionByZeroError $e){
    $result = 0;
}

This revised code ensures that when a division by zero occurs, the DivisionByZeroError exception is specifically caught and an appropriate action is taken, such as setting $result to 0.
