How can error_reporting(E_ALL) and '@' error suppression affect error detection in PHP scripts?

Using error_reporting(E_ALL) ensures that all errors, warnings, and notices are displayed, helping developers identify and fix issues in their PHP scripts. On the other hand, using '@' error suppression operator silences any errors that occur, making it difficult to detect and troubleshoot problems in the code. It is recommended to avoid using '@' error suppression and instead rely on error_reporting(E_ALL) to effectively handle errors.

// Set error reporting to display all errors
error_reporting(E_ALL);

// Example code snippet with potential error
$number = 10;
echo $undefinedVariable; // This will generate a notice

// Correct way to handle errors without using '@' error suppression
if(isset($undefinedVariable)) {
    echo $undefinedVariable;
}
