What practices do you apply to minimize errors when developing code?

To minimize errors when developing PHP code, I apply the following practices:

• Using strict typing (declare(strict_types=1);) for early detection of type mismatches.
• Code coverage with tests — unit tests with PHPUnit help identify errors early.
• Code review — collaborative code checking by colleagues reduces bugs.
• Using static code analysis (e.g., PHPStan or Psalm) to detect potential errors.
• Clean and readable code — adhering to coding standards (PSR), clear variable and function names.
• Error and exception handling — using try-catch blocks and proper error logging.

Example of strict typing and exception handling:

<?php
declare(strict_types=1);

function divide(int $a, int $b): float {
    if ($b === 0) {
        throw new InvalidArgumentException('Division by zero');
    }
    return $a / $b;
}

try {
    echo divide(10, 0);
} catch (InvalidArgumentException $e) {
    echo 'Error: ' . $e->getMessage();
}

These practices help write more reliable and maintainable code.
