How can syntax errors, such as the unexpected ';' in the PHP code, be avoided or quickly identified and resolved?

To avoid syntax errors like unexpected ';', it is important to carefully review the code for any typos or misplaced characters. Using an integrated development environment (IDE) with syntax highlighting can help identify errors quickly. Additionally, running the code through a syntax checker tool can catch any issues before execution.

// Incorrect code with unexpected ';'
$name = "John";
if ($name == "John") {
    echo "Hello, John";
};
```

```php
// Corrected code without unexpected ';'
$name = "John";
if ($name == "John") {
    echo "Hello, John";
}
