IntlChar::chr — Return Unicode character by code point value
public static IntlChar::chr ( mixed $codepoint ) : string
Returns a string containing the character specified by the Unicode code point value.
This function compliments IntlChar::ord().
codepoint
The int codepoint value (e.g. 0x2603
for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}"
)
A string containing the single character specified by the Unicode code point value.
Example #1 Testing different code points
<?php $values = ["A", 63, 123, 9731]; foreach ($values as $value) { var_dump(IntlChar::chr($value)); } ?>
The above example will output:
string(1) "A" string(1) "?" string(1) "{" string(3) "☃"
