How can PHP syntax errors be identified and resolved in code to ensure proper functionality?

PHP syntax errors can be identified by carefully reviewing the error messages provided by the PHP interpreter. Common syntax errors include missing semicolons, parentheses, or curly braces. To resolve these issues, carefully check the code for any missing or misplaced syntax elements and make the necessary corrections. Example PHP code snippet:

<?php
// Syntax error: missing semicolon
$variable = 10
echo $variable;
?>
```

To fix the syntax error in the above code snippet, simply add a semicolon at the end of the first line:
```php
<?php
$variable = 10; // Fixed syntax error
echo $variable;
?>
