How can PHP scripts be optimized to prevent Apache or PHP from crashing during execution?

To prevent Apache or PHP from crashing during execution, PHP scripts can be optimized by reducing memory usage, improving code efficiency, and handling errors properly. This can be achieved by limiting the use of large data structures, optimizing loops and functions, and implementing error handling mechanisms such as try-catch blocks. 

// Example code snippet demonstrating error handling with try-catch block
try {
    // Code that may potentially cause errors or exceptions
    $result = 1 / 0;
} catch (Exception $e) {
    // Handle the error or exception gracefully
    echo "An error occurred: " . $e->getMessage();
}
