What are some common methods to include ASCII characters in a PHP string, especially when the editor cannot display the character?

When working with ASCII characters in a PHP string, especially when the editor cannot display the character properly, you can use escape sequences to include the desired ASCII character. One common method is to use the backslash followed by the ASCII code in octal or hexadecimal format to represent the character. Another approach is to use the `chr()` function to convert an ASCII code to its corresponding character. 

// Using escape sequences with octal ASCII code
$string = "Hello \x48\x65\x6C\x6C\x6F World";

// Using chr() function to include ASCII character
$ascii_code = 72; // ASCII code for 'H'
$string = "Hello " . chr($ascii_code) . " World";
