PHP致命错误：未捕获错误：调用未定义函数getheaders（）

Question

when I run my code I get this error

PHP Warning: log() expects parameter 1 to be float, string given in /opt/lampp/htdocs/x/websocket/server.php on line 2 PHP Fatal error: Uncaught Error: Call to undefined function getheaders()

my code

<?php 
log("Handshaking...");
list($resource,$host,$origin) = getheaders($buffer);
$upgrade = "HTTP/1.1 101 Web Socket Protocol Handshake\r\n" .
           "Upgrade: WebSocket\r\n" .
           "Connection: Upgrade\r\n" .
           "WebSocket-Origin: " . $origin . "\r\n" .
           "WebSocket-Location: ws://" . $host . $resource . "\r\n" .
           "\r\n";
$handshake = true;
socket_write($socket,$upgrade.chr(0),strlen($upgrade.chr(0)));

what's the wrong ?

Answer 1

Look at the doc: http://php.net/manual/en/function.log.php log is not for "Logs".

Try with file_put_contents().

for getheaders() the correct syntax is "get_headers()"
