How do different keyboard layouts affect the input of single quotation marks in PHP code?

Different keyboard layouts may have single quotation marks mapped to different keys, leading to issues when inputting them in PHP code. To ensure consistent input of single quotation marks, it is recommended to use the ASCII value for single quotation marks (') which is 39. This way, regardless of the keyboard layout, the input will be interpreted correctly in PHP code. 

// Using ASCII value for single quotation marks to ensure consistent input
$variable = 'This is a string with single quotation marks: ' . chr(39) . 'Hello' . chr(39);
echo $variable;
