How can proper error handling techniques improve the efficiency of PHP coding projects?

Proper error handling techniques can improve the efficiency of PHP coding projects by helping developers identify and address issues quickly, leading to more stable and reliable code. By implementing error handling, developers can catch and handle errors gracefully, preventing unexpected crashes and improving the overall user experience. 

// Example of implementing proper error handling in PHP

// Set error reporting level
error_reporting(E_ALL);

// Set error handler function
function errorHandler($errno, $errstr, $errfile, $errline) {
    echo "Error: [$errno] $errstr - $errfile:$errline";
    die();
}

// Set error handler
set_error_handler("errorHandler");

// Example of triggering an error
$var = 1;
if ($var > 0) {
    trigger_error("Value must be less than or equal to 0", E_USER_ERROR);
}
