Functions

Check IE

This will check your visitor's User Agent, allowing you to specify different class(es) for users with Internet Exploder.

function chkIe($class) {
    /*
    Usage: <div class="<?php echo chkIe($classname);?>"> Insert the Element(s) IE doesn't render right. </div>
    Of course any element that can use the class attribute may be used.
    */
    $agent = $_SERVER['HTTP_USER_AGENT'];
    if (preg_match("/MSIE/", $agent)) {
        $r = $class . "_ie";
    }
    else {  
        $r = $class; 
    }
    return $r;
}

Get Home

For Shared Hosts who's web root is as similar to /home/user/public_html/

function getHome (){
    $home_array = $_SERVER['SCRIPT_FILENAME'];
    $home_split = split ('/', $home_array);
    $home = "/".$home_split['1']."/".$home_split['2'];
    return $home;
}

Test if Curl is working

Make sure the cURL PHP Extension is functioning properly on a server.

function testCurl() { // Can work with HTTPS also
        $user = "";  // For any 401 Response
        $pass = "";  // Also for any 401 Response.
	$url = "http://www.google.com/";
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);
	//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
	curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
	curl_setopt($ch, CURLOPT_USERPWD, "$user:$pass"); //Use this if a 401 Response is given
 
	if($data = curl_exec($ch) === false)
	{
	    echo 'Curl error: ' . curl_error($ch);
	}
	else 
        {
	    print "Data: \n";
	    print $data;
	}
}
