PHP Logging and Debugging
PHP provides several tools for logging and debugging: error_log(), var_dump(), print_r(), and custom try-catch error handling.
PHP में लॉगिंग और डिबगिंग के लिए error_log(), var_dump(), print_r() और try-catch जैसी सुविधाएँ मिलती हैं।
Example: error_log()
<?php
$name = "";
if ($name == "") {
error_log("Name is empty!", 3, "logs/errors.log");
echo "Error logged.";
}
?>Error logged. (Check logs/errors.log)
Debug Output using var_dump()
<?php
$data = ["name" => "John", "age" => 30];
var_dump($data);
?>array(2) { ["name"]=> string(4) "John" ["age"]=> int(30) }
Try-Catch Logging
<?php
try {
throw new Exception("Something broke!");
} catch (Exception $e) {
error_log($e->getMessage(), 3, "logs/exception.log");
echo "Exception handled.";
}
?>Exception handled. (Logged in exception.log)
