PHP - Best Way To Make A Script Restart Itself (resume) Repeatedly Without Timeouts?

haw can I make a commit script , when I click on button the commit inserted in the table and browsed immediately without refresh the page , like Facebook commits  ? 

Hello, I need help in making my script loop indefinitely. Any ideas?

I read the tutorial, "Handling XML Data" and created this script from it. Excellent tutorial by the way

Here is my script:
Code: [Select]
<?php
// load SimpleXML
$fx = new SimpleXMLElement('http://www.boj.org.jm/uploads/fxrates.xml', null, true);

echo '<table><tr class="fx_header"><th class="fx_date">';
echo $fx->US[0]->DATE;
echo '</th><th class="fx_buy">Buy</th><th class="fx_sell">Sell</th></tr><tr class="fx_us"><td class="fx_legend">USD (&#38;#36;)</td><td class="fx_buy_sell">&#38;#36;';
echo $fx->US[0]->BUY;
echo '</td><td class="fx_buy_sell">&#38;#36;';
echo $fx->US[0]->SELL;
echo '</td></tr><tr class="fx_cad"><td class="fx_legend">CAD (&#38;#36;)</td><td class="fx_buy_sell">&#38;#36;';
echo $fx->CAD[0]->BUY;
echo '</td><td class="fx_buy_sell">&#38;#36;';
echo $fx->CAD[0]->SELL;
echo '</td></tr><tr class="fx_gbp"><td class="fx_legend">GBP (&#38;#163;)</td><td class="fx_buy_sell">&#38;#36;';
echo $fx->GBP[0]->BUY;
echo '</td><td class="fx_buy_sell">&#38;#36;';
echo $fx->GBP[0]->SELL;
echo '</td></tr></table>';
?>

This is the XML file that the script is reading from: http://www.boj.org.jm/uploads/fxrates.xml

This is the result page (which is just the way it should look): http://projects.wstudiographics.com/ewl/boj/fxrates.php

It works very well, but it take a bit of time to return the result. I think it's because of how the XML file data was set up. The thing is that I have no control over the xml data. I am only allowed to read it. I only need the first or rather latest instance of the data.

Any help on this will be greatly appreciated. Thanks in advanced.

Seems to be a basic question, but I couldn't find an answer nor figure it out on my own.

Basically I have a script that takes out specific data out of the database, the script works on its own, now I just need a way to make the user execute it with a link or a button.

Example:
Category: [Smileys] - [Category2] - [Category3] - etc.

As soon as the user clicks on [Smileys] all data in the database which contains the word smileys in the category field gets selected and outputted as a list.

Again the script works, I just need to be able to execute it with a button.

If I understood it correctly I have to run the script by adding a
if (isset($_POST['Smileys'])) {
in front of the script.

But how do I build the connection with the text link?

Hi guys, It's my first post here, not looking to leech, I'm simply here to learn and develop my skills and any contributes will be greatly appreciated!

Anyways I have made a simple login script, however I would like to make it more secure. However before that, can you please explain to me as to why it is not secure in the first place? A basic explanation so I can understand would be great.   

Then after that, could you please give help as to how I would make this login code more secure?

Thank you very much

Code: [Select]
<?php
   $rowsfound=false;
    if (isset($_GET['frmStudentId']))
    {
           // functions to make performQuery() work correctly
           require_once("dbfunctions.inc.php");
           $query = "SELECT dbStudentId, dbStudentName " .
           " FROM student " .
           " WHERE dbStudentId = '".$_GET['frmStudentId']."'" .
           " AND dbPassword = '".$_GET['frmPassword']."'";
           $result = performQuery($query);
           if(count($result) > 0)
           {
           $rowsfound=true; // allow login
           }
           }
// code continues by generating appropriate response ...

Happy New Year, folks!

I am having an issue that's been dragging my life for quite some time. I am creating a website for my church maranatha.tv

The site's Menu and Content are pulled from a MySQL database I created. As far as this goes, everything is fine; content is pulled from my database with no issues.

My problem is as follow:
I am including an online bible, which is a third party script I downloaded. This scripts comes with its own database, which I have installed for use in my web server. I used Include() to include the index.php file of the online bible script, from its folder. I just don't know if this the right way to do it.

Of course, this script has its own folder and a set of files which makes up the entire bible script. I use an if condition so that when the user clicks on the menu button BIBLE, the script's index.php file is included instead of text from my database. This way of adding the third party script is rendering some unwanted results such as layout distortion (which I don't care at this point), broken links (main issue), and links (although broken) are sent to new pages, instead of staying within my site's CONTENT page template.

I need to find a way to make my script more modular so everything renders as intended. Here's my content function:
Code: [Select]
function content(){

// DETERMINE which page ID to USE in our query below ********************

if (!isset($_GET['jesusid'])) {

$pageid = '1';

} else {
$pageid = preg_replace('#[^0-9]#i', '', $_GET['jesusid']);} // filter everything but numbers for security)
//preg_replace($pattern, $replacement, $string);//preg_replace() Function structure

// Query the body section for the proper page
$query = mysql_query ("SELECT body_text,title,linklabel, author FROM content WHERE id = '$pageid' LIMIT 1 ") or die (mysql_error()); 

while ($row = mysql_fetch_array($query)) {

echo ucwords($row['title']).' por ';

echo '<b>'.$row['author']. '</b><br>';
        echo ucwords($row['body_text']);

//Add Bible Script
if (ucwords($row['title'])=='Biblia') //use row title -- UPPERCASED word
   {
     include ('bible/__WINDOWS/search.php');
   }

 }
}

?>
Just click on the BIBLE button, and then on any link within that page and you will see what I mean. I am still learning PHP and I don't have any background integrating third party scripts to an existing PHP website. I hope someone can help me.

Thanks in advance for your assistance.

I know it needs a for loop, but i don't know where in the code i should be putting it?

Code: [Select]
function check_input($value)
{
// Stripslashes
if (get_magic_quotes_gpc())
  {
  $value = stripslashes($value);
  }
// Quote if not a number
if (!is_numeric($value))
  {
  $value = "'" . mysql_real_escape_string($value) . "'";
  }
return $value;
}

$_POST = array_map('check_input', $_POST);

$sql="INSERT INTO testimonials (CustomerName, Town, Testimonial, SortOrder, Images)
VALUES
({$_POST['customername']}, {$_POST['town']}, {$_POST['testimonial']}, {$_POST['sort_order']}, '$imgname'

)";

}
if (!mysql_query($sql,$con))
  {
  die("<br>Query: $sql<br>Error: " . mysql_error() . '<br>');
  }
echo "<p align=center><b>1 testimonial added</b></p>";

mysql_close($con);


Thanks in Advance,

Hello !   How I can make a script of my PHP code to work even if my website is not running   Can I make this with php ? 

In one of my servers when ever I call sleep or usleep functions my script sleeps and never wakes up,
Any suggestion on what can cause the issue?
my php -v output:
Code: [Select]
PHP 5.2.17 (cli) (built: Jan 24 2012 20:49:48)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies

Hi there, As the question says i tried several things but i can't work it out and my knowledge about php isn't that well.

$looponce = 1;
foreach ($this->info as $k => $v) {
if ( (($k == 'subject') && ($v['required'])) && (!$this->settings['customSubject'])) {
for ($i = 0; $i <= 0; $i++) {
$output[] = $this->display_errors('error_system_subject');
}
}
if ( (($k == 'name') && (!$v['required'])) || ((!array_key_exists("name", $this->info)) && ($looponce == 1)) ) {
$output[] = $this->display_errors('error_system_name');
$looponce++;
}
}

That is my loop that i check things in. What i'm more interested in is the name if statement.

If currently checks for a name key in an array(below) and makes sure that it is set to required. If it's not set to required, print out a system error and die()'s.

I'm looking for ways to remove the need for program errors and just change them to what is needed to run.

What i know how to do is, get into the inner array, what i don't know is how to edit the data and put it back exactly as it was given to me. The inner array data can be put back in any order, but the outer array must be in exact order as it was given.


above code $this->info = $formdata;

$formdata = array(
'name' => array('name'=>"Full Name", 'required'=>false, 'type'=>'text'), # This needs to be required=>true, but i can't trust the user, which is why i have the error.
'telephone' => array('name'=>"Telephone", 'required'=>false, 'type'=>'phone'),
);


Any help is greatly appreciated, also am i doing the foreach loop in the code above in an efficient manner or is there another way?
