How can proper debugging techniques help identify errors in PHP code more efficiently?

Proper debugging techniques in PHP, such as using var_dump(), error_reporting(), and debugging tools like Xdebug, can help identify errors more efficiently by providing detailed information about the issue, such as variable values, line numbers, and error messages. By carefully analyzing this information, developers can pinpoint the root cause of the problem and make necessary corrections. 

<?php
// Example code with a potential error
$number1 = 10;
$number2 = 0;
$result = $number1 / $number2;
echo $result;
?>
```

To fix the division by zero error in the code snippet above, you can add a conditional check to ensure that the divisor is not zero before performing the division operation. 

```php
<?php
// Fixing the division by zero error
$number1 = 10;
$number2 = 0;

if($number2 != 0){
    $result = $number1 / $number2;
    echo $result;
} else {
    echo "Cannot divide by zero.";
}
?>
