I'm wanting to set up a loop or maybe a page refresh that pings my server over and over again and tells me the milliseconds.
This is the code I'm using but not sure how to make it keep refreshing and giving me the response live. Can someone show me how to make it live so it constantly updates every 1 second or even every 2 or 3 seconds is fine also. Just need it to be live.
<?php
function pingDomain($domain){
$starttime = microtime(true);
// supress error messages with #
$file = #fsockopen($domain, 80, $errno, $errstr, 10);
$stoptime = microtime(true);
$status = 0;
if (!$file){
$status = -1; // Site is down
}
else{
fclose($file);
$status = ($stoptime - $starttime) * 1000;
$status = floor($status);
}
return $status;
}
?>
Server Latency: <?php echo pingDomain('192.168.1.20'); ?> ms<br>
Edited with Paul's Code still no luck:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html;" />
<meta http-equiv="refresh" content="1; url='yourPage.php'" />
</head>
<body>
<?php
function pingDomain($domain){
$starttime = microtime(true);
// supress error messages with #
$file = #fsockopen($domain, 80, $errno, $errstr, 10);
$stoptime = microtime(true);
$status = 0;
if (!$file){
$status = -1; // Site is down
}
else{
fclose($file);
$status = ($stoptime - $starttime) * 1000;
$status = floor($status);
}
return $status;
}
?>
Server Latency: <?php echo pingDomain('192.168.1.20'); ?> ms<br>

There are two ways I can think of:
1.Setting up refresh attribute in the page header
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html;" />
<meta http-equiv="refresh" content="1; url='yourPage.php'" />
</head>
<body>
<?php
//your php code here
?>
</body>
</html>
2.Use a crontab job to execute this command every second:
w3m http://yourhost/yourPage.php
I think the first solution is closer to what you need.

I have issue to redirect another location after fopen() function in php. below is my function which i m using.
<?php
function create_file($filename){
$my_file = 'folder/index.php';
$fh = fopen($my_file, "wb");
$data = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Some data</title>
</head>
<body>Here some data</body>
</html>';
fwrite($fh, $data);
fclose($fh);
return true;
ob_end_clean();
exit();
}
$file = create_file(test);
if($file == true){
$url = 'http://example.com';
return $url;
}
else{
return 0;
}
?>
If you want to redirect in PHP, you cannot send any output to the server before header("Location: http://example.com");.
This includes any HTML, text or white spaces that aren't wrapped in a PHP tag set.
The header function must be called before any page output (if HTML has already been displayed, it's too late for your headers!).
I'm trying to create a page what will log a plethora of user data for security purposes but am am unsure how best to do so.
Ideally I want all important stats for example their IP, their X-Forward IP, their browser, operating system and any other details I can get.
I've also got problems showing the variables in a php / html page as shown below:
<?php
$ip = <?= $_SERVER['REMOTE_ADDR'];
$template = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Title</title>
</head>
<body>
IP: <?= $ip ?>
IP: [IP]
</body>
</html>';
$template = str_replace('[IP]', $ip, $template);
echo $template;
?>
or
<?php
$ip = <?= $_SERVER['REMOTE_ADDR'];
echo $ip;
?>
Try something simple first:
<?php
$ip = $_SERVER['REMOTE_ADDR'];
echo $ip;
?>
For a full list of SERVER superglobal variables, check this link http://php.net/manual/en/reserved.variables.server.php
<?php
$data = $_SERVER;
$IP = $data['REMOTE_ADDR'];
echo "IP address is:" . $IP;
?>
There you go... now look up all the available $_SERVER values and use the ones you need.

The download.php is a ready made API php script to provide webmasters upload to their FTP. Webmasters can be choose many options(e.g: download.php?words=2000&sort=popular&type=xml) from a form, then submit the form to get their custom API script.
This is the line that will replace the options after they submit the form.:
$url = "http://api.xxx.com/info.php?words=".$_GET['words']."&sort=".$_GET['sort']."&type="$_GET['type'];
This is the code to force download. But i don't know how to wrap whole page with $content = "";. I know how to wrap the HTML codes but how to wrap the PHP function and codes on the page?
header("Content-Disposition: attachment; filename="download.php");
print $content;
Not sure if that is what yo want; but you could create a second script that calls the first one, gets the output, and sends that with the mentioned headers:
<?php
$words = (int) $_GET['words'];
$sort = $_GET['sort'];
$url = sprintf("http://localhost/wherever/download.php?words=%d&sort=%s&type=xml", $words, $sort);
$content = file_get_contents($url);
header("Content-Disposition: attachment; filename="download.php");
print $content;
?>
Call that file "force_download.php" and let the users call Download php file instead.
Whether I enter the value for bug id or not ..in both conditions the code between php tags is displayed as output. Can someone help me to find out the reason.
Code is given below:

If you're getting PHP code in the output, then your webserver isn't running that page/script through the PHP interpreter. Generally, that's because you've put the code into a .html file, which is not treated as PHP by default.
Either rename the file to whatever.php, or reconfigure your webserver to treat .html files as PHP scripts.
check that php is working or not for that write the code <?php phpinfo(); ?> and if have manually installed php apache and getting problem try wamp server
your code is widely open for sql-injunction to make it secure use
public function mysql_prep( $value ) {
$magic_quotes_active = get_magic_quotes_gpc();
$new_enough_php = function_exists( "mysql_real_escape_string" ); // i.e. PHP >= v4.3.0
if( $new_enough_php ) { // PHP v4.3.0 or higher
// undo any magic quote effects so mysql_real_escape_string can do the work
if( $magic_quotes_active ) { $value = stripslashes( $value ); }
$value = mysql_real_escape_string( $value );
} else { // before PHP v4.3.0
// if magic quotes aren't already on then add slashes manually
if( !$magic_quotes_active ) { $value = addslashes( $value ); }
// if magic quotes are active, then the slashes already exist
}
return $value;
}
Check whether php is running or not in your machine. Save the below code as test.php and run it through
<?php
phpinfo();
?>
In that case you have to run on that Server which support PHP like Xampp or Wamp and also extension of the file should be .php
I have been racking my brains over this for hours, I need to pass some html to a function and have it replace the links and the return the html with the replaced links.
<?php
final static public function replace_links($campaign_id, $text) {
$regexp = "<a\s[^>]*href=(\"??)([^\" >]*?)\\1[^>]*>(.*)<\/a>";
if(preg_match_all("/$regexp/siU", $text, $matches, PREG_SET_ORDER)) {
foreach($matches as $match) {
if(substr($match[2], 0, 2) !== '##') { // ignore the placeholders
if(substr($match[2], 0, 6) !== 'mailto') { // ignore email addresses
// $match[2] = link address
// $match[3] = link text
$url = "http://xxx.com/click?campaign_id=$campaign_id&email=##email_address##&next=" . $match[2];
#$text .= str_replace($match[2], $url, $text);
#echo $links . "\n";
preg_replace($match[2], "<a href='$url'>{$match[3]}</a>", $match[2]);
}
}
return $text;
}
}
}
?>
When I echo the links it shows all the matched links. Question is how do i return the complete HTML with the replaced links example below.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

Should become:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Hope this makes sense.
Thanks in advance,

Don't reinvent the wheel just use something like this:
http://code.google.com/p/jquery-linkify/
It's really easy i use it as well
I don't know much about preg_replace, but i needed exatcly the same function as you.
Changing the line:
preg_replace($match[2], "<a href='$url'>{$match[3]}</a>", $match[2]);
for this:
str_replace($match[0],$url,$text);
seems to do the trick.
I just needed to get the return from this functions, so:
//$text = preg_replace($match[2], "<a href='$url'>{$match[3]}</a>", $match[2]);
$text = str_replace($match[0],$url,$text);
