The `chr()` function in PHP is used to return a character from a specified ASCII value. In PHP 7.4, this function works the same way as in other versions.
Syntax:
chr(int $ascii): string
`$ascii`: An integer between 0 and 255.
Example:
Here’s an example of how to use the `chr()` function in PHP 7.4:
<?php // ASCII value for 'A' is 65 $character = chr(65); echo $character; // Output: A // ASCII value for 'Z' is 90 $characterZ = chr(90); echo $characterZ; // Output: Z // ASCII value for 'a' is 97 $characterLowerA = chr(97); echo $characterLowerA; // Output: a // ASCII value for 'z' is 122 $characterLowerZ = chr(122); echo $characterLowerZ; // Output: z ?>
The `chr()` function can be particularly useful when you need to convert ASCII codes to their corresponding characters in PHP.
