How can PHP version compatibility affect the syntax of array notation?

PHP version compatibility can affect the syntax of array notation because newer versions of PHP may introduce new features or deprecate old ones. To ensure compatibility across different PHP versions, it's important to use array notation that is supported by all versions you are targeting. One way to solve this issue is to use the `array()` function to define arrays instead of shorthand array notation.

// Define an array using the array() function for better compatibility
$myArray = array('apple', 'banana', 'cherry');
