fromcharcode

Is there a PHP function that takes an integer and return the unicode character of that number? No, but you can easily make one: <?php /** * Return unicode char by its code * * @param int $u * @return char */ function unichr($u) { return mb_convert_encoding('&#' . intval($u) . ';', 'UTF-8', 'HTML-ENTITIES'); } ?> Taken from: PHP Manual - chr - comments Look at this: http://php.net/manual/en/function.utf8-encode.php 来源： https://stackoverflow.com/questions/9878483/php-equivlent-of-fromcharcode

I might be asking the wrong question here, so I apologize if the answer is on another thread... but I've looked around to no avail. in a snippet, why doesn't this work? array = [72,69,76,76,79]; document.write(String.fromCharCode(array)); I'm collecting key events in an array and want to be able to write them out as chars when prompted. And though this works: document.write(String.fromCharCode(72,69,76,76,79)); I can't seem to get it to work when I pass it along as an array. I've also tried to convert the array toString() first, as well array.join(","); to create a comma separated list ...yet
