PHP - How Can I Find Missing Numbers?

Really not seeing where my missing parenthesis goes.

Code: [Select]
if(isset($this->uri->segment(3)) AND ((empty($this->uri->segment(3))||($this->uri->segment(3) === FALSE)||(trim($this->uri->segment(3)) == '')))

Let's say I have an array:

$myArray[0] = "AtG2";
$myArray[1] = "AtG4";
$myArray[2] = "AtG1";
$myArray[3] = "AtG3";
$myArray[4] = "AtG5";

I want to sort it alphanumerically, so that the key/value pairs are as follows:
[zero*] => "AtG1"
[1] => "AtG2"
[2] => "AtG3"
[3] => "AtG4"
[4] => "AtG5"

* = I have to write [zero] because putting an actual zero number inside of [ and ] braces converts it to an HTML list bullet.

It *appears* that natsort() is the proper function for this. The only problem I'm having is that natsort() doesn't manipulate key/value pairs.  To confuse me even more, literally every example I can find on using natsort() uses it in conjunction with print_r() like so:

natsort($someArray);
print_r($someArray);

Obviously, something is happening to $someArray when passed to natsort(), otherwise, print_r() wouldn't be able to order the indices in synch with the natural ordering algorithm.

Well, I don't need my web app to use print_r()! I just need the darn key/value pairs reordered so that when I echo $myArray[3], I know I'm going to get "AtG4".

What am I missing here? What is the point of calling it a "sort" if it doesn't manipulate the key/value pairs??? How can I get what I want?!?

well when i am in my forum thing and i go to click on a 'topic' it says no topic exists. and there is one there idk what im missing in the code to make it view it in my table..

Code: [Select]
<?php require("top.php");

?>
<div id='content'>

<div id='homepageright'>
<?php

include_once("scripts/connect.php");

if($username){


$cid = $_GET['cid'];
$tid = $_GET['tid'];

$sql = "SELECT * FROM topics WHERE category_id='".$cid."' AND id='".$tid."' LIMIT 1";
$res = mysql_query($sql) or die(mysql_error());

if(mysql_num_rows($res) == 1){

echo "<table width='100%'>"; 
if($username){
echo "<tr><td colspan='2'><input type='submit' value='Add Reply' onClick=\"window.location = post_reply.php?cid=".$cid."&tid=".$tid."\" /><hr /> ";
}

While ($row = mysql_fetch_assoc($res)) {
$sql2 = "SELECT * FROM posts WHERE category_id='".$cid."' AND topic_id= '".$tid."'";
$res2 = mysql_query($sql2) or die(mysql_error());
while ($row2 = mysql_fetch_assoc($res2)) {
echo "<tr><td valign='top' style='border: 1px solid #000000;'><div style='min-height: 125px;
'>".$row['topic_title']."<br /> by ".$row2['post_creator']." - ".$row2['post_date'].
"<hr /> ".$row2['post_content']."</div></td><td width='200' valign='top' 
align='center' style='border: 1px solid #000000;'>User Info Here</td></tr><tr><td 
colspan='2'><hr /></td></tr>";
}
echo "</table>";

}

}

else{
echo "This Topic Does Not Exist.";
}

}
else{
echo "You Must Be Logged In To Continue.";
}
?>
</div>
<div id='homepageleft'>

I am running a search query from MYSQL and it works, but now I want to get a little custom.

I am selecting one field, out of many called paid1 which in database is either Yes or No. I want to do this: if paid1 is NO display Pay Now and everything else display Yes. I want this to be under new heading of paid1b. So the code should look something like this:

$paid1b= if(['paid1'}==No){echo "Pay Now";} else {echo "YES";}

But I am missing something somewhere. What is it?
Thanks

The user will click on the first button (.Applybutton) which opens a bootstrap modal with the ID ApplyModal. From then on an apply button (.SendButton) will send the job id that is passed in the first button press $_POST['jobid'] to the database.

I'm using the following script to download large file (>100Mb). It works well except that it seems to not ever save the final chunk. If the file is 149,499 on the server, it finishes its download at 145,996. Why? How do I get the last 2% or so to flush and complete the download? Thank much for your help.

FYI, this also happens the same on smaller files so its not stopping for time or file size issues.

Code: [Select]

$path = "the/file/path.mp4";

$headsize = get_headers($path,1);

$ext = str_from_last_occurrence($_vars['filepath'],".");

if ($ext=="mp3") { $type = "audio"; }
elseif ($ext=="mp4") { $type = "video"; }

function readfile_chunked($filename,$retbytes=true) {

// Stream file
$handle = fopen($filename, 'rb');
$chunksize = 1*(1024*1024); // how many bytes per chunk
$buffer = '';
$cnt =0;

   if ($handle === false) {
       return false;
   }

   while (!feof($handle)) {
       $buffer = fread($handle, $chunksize);
       echo $buffer;
       ob_flush();
       flush();
       if ($retbytes) {
           $cnt += strlen($buffer);
       }
   }

   $status = fclose($handle);

   if ($retbytes && $status) {
       return $cnt; // return num. bytes delivered like readfile() does.
   }

   return $status;

}

header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate');
header("Content-type: ".$type."/".$ext);
header('Content-Length: ' . (string)($headsize['Content-Length']));
header('Content-Disposition: attachment; filename="'.str_from_last_occurrence($_vars['filepath'],"/").'"');
header("Content-Transfer-Encoding: binary");

readfile_chunked($path);

exit;

I am trying to get a paragraph from a website. Everything works but the first letter is kept on missing. The code shown below is used to get the paragraph. Not sure why the first letter is missing. Please help!!!

Code: [Select]
if ( isset( $offer[ 0 ] ) )
{
// Tidy it up - remove commas and weird Word chars
$off = strip_tags( $offer[ 0 ] );
$off = substr( $off, strpos( $off, ";" ) + 1 );
$off = str_replace("'", "", $off );
$off = trim( $off );

}
else
{
$off = "0";
}

nothing is echoed
for the second foreach???
foreach($pictures as $picture)
-im breaking cause it's a large file


Code: [Select]
$doc = new DOMDocument();
$doc->load('accommodation.xml');

$i = 0;

$accommodations = $doc->getElementsByTagName('accommodation');
foreach($accommodations as $accommodation) {
if(++$i > 2) break;
$supplierID = $accommodation->getElementsByTagName('code')->item(0)->nodeValue;
 $pictures = $accommodation->getElementsByTagName('pictures')->item(0)->nodeValue;
 $pictures=array();
foreach($pictures as $picture) {
echo $url = $picture->getElementsByTagName('url')->item(0)->nodeValue;

}

Hey guys

I'm not amazing at PHP, but know just enough to be dangerous. 

Basically I'm trying to get these records from my database to display in rows of 4.  For some reason every time, I'm missing a record (the first record returned in my query).  It's probably something simple is my code.  Would be grateful if anyone could lend a suggestion. 

Code: [Select]
<?php 
         $a=0;
         $b=3;
          
          while ($ArrayData = mysql_fetch_array($QueryData)) {
          
          //if a=0, start new row
            if ($a==0) {
            echo '<tr>';
            }
          
          //create cell
          //if thumbnail exists, use it, otherwise throw in the unavailable image
          if ($ArrayData["PhotoThumb"]!="") {
          $ImageToUse = $ArrayData["PhotoThumb"]; 
          } else {
          $ImageToUse = "image_unavailable_thumb.jpg"; }
          echo '
             <td width="33%"  align="center" valign="top"><p><a href="item.php?ItemID='.$ArrayData["ItemID"].'"><img src="images/'.$ImageToUse.'" border="0" /></a></p>
              <p><a href="item.php?ItemID='.$ArrayData["ItemID"].'" class="cart_body_text">'.$ArrayData["ItemName"].'</a><br />
                 <span class="style1"> <strong>$'.sprintf("%01.2f", $ArrayData["UnitPrice"]).'</strong></span><br />
              </p>
              </td>';
        
         //increment by 1
         $a++;
        
        //if a = 3 then close the row using </tr>, ready to start a new one
        if ($a==$b) {
        echo '
        </tr>';
        
        //reset counter, ready to start new row
        $a=0;
        }
        }     
        
        if ($a > 0 ) {
           echo '</tr>';
        } 
         
    ?>
Thanks guys!

Hi,

I have set up a new website, but the old website is using /mainpage.html as it's homepage when searching in Google. This page no longer exists, so when a user clicks on the page in Google, the website is not found.

Is there a way i can set up a forwarder to point the missing file to the new index.php page?

Thanks

I've been trying to figure out this issue for a couple of days now.  I have a client that insists in using the Innovaeditor in IE.  I have placed a stylesheet in on the editors, and it breaks the scrollbar in IE.  When I take it out it returns.  I still want to preserve the styles I want to set, and be able to scroll down the editor box.  It works fine in Firefox.

Any help would be MUCH appreciated.

Hey guys, been awhile since I have been here, but I hit a little issue in reading session data reliably every time.

What I am doing is reading the variables and values from a rarurlencoded string.
Then putting that into a session array to populate parts of a form and fill in some hidden fields.
After the form posts every now and then, about 1 in 50 or so attempts, I have one (always the same one) that just vanishes.

Anyone ever experience anything like this?

Hi all -
