How does the "‘" character interact with PHP functions or operators?

The "‘" character is not a valid character in PHP, as PHP uses the single quote (') or double quote (") characters for string literals. If you encounter this character in your code, you should replace it with a valid single quote or double quote to avoid syntax errors.

// Incorrect usage of ‘ character
$invalidString = ‘Hello World’;

// Corrected code using single quotes
$validString = 'Hello World';
