How can syntax errors in PHP code be identified and corrected efficiently?

Syntax errors in PHP code can be identified by carefully reviewing the error messages provided by the PHP interpreter. Common syntax errors include missing semicolons, parentheses, curly braces, or incorrect variable names. To correct syntax errors efficiently, it is essential to carefully examine the code for any missing or misplaced syntax elements and make the necessary corrections.

// Example PHP code snippet with a syntax error
$variable = "Hello World"
echo $variable;
```

```php
// Corrected PHP code snippet
$variable = "Hello World";
echo $variable;
