(PHP 4, PHP 5, PHP 7)
chr — Return a specific character
$ascii
)
Returns a one-character string containing the character specified
by ascii
.
This function complements ord().
ascii
The extended ASCII code.
Values outside the valid range (0..255) will be bitwise and'ed with 255, which is equivalent to the following algorithm:
while ($ascii < 0) {
$ascii += 256;
}
$ascii %= 256;
Returns the specified character.
Example #1 chr() example
<?php
$str = "The string ends in escape: ";
$str .= chr(27); /* add an escape character at the end of $str */
/* Often this is more useful */
$str = sprintf("The string ends in escape: %c", 27);
?>
Example #2 Overflow behavior
<?php
echo chr(-159), chr(833), PHP_EOL;
?>
