How can syntax errors, such as missing semicolons, impact the functionality of PHP code?

Syntax errors, such as missing semicolons, can cause PHP code to fail to execute properly. The absence of a semicolon can disrupt the structure of the code and lead to unexpected behavior or errors. To resolve this issue, it is important to carefully review the code for missing semicolons and ensure that they are added in the appropriate places.

// Incorrect code with missing semicolon
echo "Hello, World"
```

```php
// Corrected code with semicolon added
echo "Hello, World";
