How can syntax errors be identified and resolved in PHP code?

Syntax errors in PHP code can be identified by carefully reviewing the code for any typos, missing semicolons, parentheses, or curly braces. Resolving syntax errors involves correcting these mistakes to ensure the code follows the correct PHP syntax rules.

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

To resolve the syntax error in the code snippet above, add a semicolon at the end of the first line:

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