Javascript function in PHP fromCharCode()
提问by LIGHT
var test = String.fromCharCode(112, 108, 97, 105, 110);
document.write(test);
// Output: plain
Is there any PHP Code to work as String.fromCharCode()of javascript?
是否有任何 PHP 代码可以作为String.fromCharCode()javascript工作？

Try the chr()function:
试试这个chr()功能：
Returns a one-character string containing the character specified by ascii.
返回一个包含由 ascii 指定的字符的单字符字符串。
回答by Baba
PHP has chrfunction which would return one-character string containing the character specified by ascii
PHP 有chr函数，它会返回一个包含 ascii 指定字符的字符串
To fit your java script style you can create your own class
为了适应您的 Java 脚本风格，您可以创建自己的类
$string = String::fromCharCode(112, 108, 97, 105, 110);
print($string);
Class Used
使用的类
class String {
public static function fromCharCode() {
return array_reduce(func_get_args(),function($a,$b){$a.=chr($b);return $a;});
}
}

Try something like this..
尝试这样的事情..
// usage: echo fromCharCode(72, 69, 76, 76, 79)
function fromCharCode(){
$output = '';
$chars = func_get_args();
foreach($chars as $char){
$output .= chr((int) $char);
}
return $output;
}

$output = implode(array_map('chr', array(112, 108, 97, 105, 110)));
And you could make a function:
你可以创建一个函数：
function str_fromcharcode() {
return implode(array_map('chr', func_get_args()));
}
// usage
$output = str_fromcharcode(112, 108, 97, 105, 110);

The chr()function does this, however it only takes one character at a time. Since I'm not aware of how to allow a variable number of arguments in PHP, I can only suggest this:
该chr()函数执行此操作，但一次只需要一个字符。由于我不知道如何在 PHP 中允许可变数量的参数，我只能建议：
function chrs($codes) {
$ret = "";
foreach($codes as $c) $ret .= chr($c);
return $ret;
}
// to call:
chrs(Array(112,108,97,105,110));
