I am seeing this error on front page of one of my website
Parse error: syntax error, unexpected '<
Some code has been hidden for security* but the source of that error is index.php. On examining my index.php i see a line of code referncing index_old.php. The code on the that file is as shown
<html>
<head></head>
<body>
<?php
$ip=$_SERVER["REMOTE_ADDR"];
$logfilename1=dirname(__FILE__).'/htaccess.log';
$fp2=fopen($logfilename1,"a");
fwrite($fp2,$ip);
fwrite($fp2," ".$_SERVER["SERVER_ADDR"]." ".$_SERVER["HTTP_HOST"]);
fwrite($fp2," ".$_SERVER['HTTP_USER_AGENT']);
fwrite($fp2," ".strftime('%c')."\r\n");
fclose($fp2);
?>
</body>
</html>
I am cracking my head to find out if the site has been infiltrated or injected with suspicious scripts. Could anyone help me figure out this?
