<?php
$row = 1;
//open the file
if (($handle = fopen("file.csv", "r")) !== FALSE)
{
    while (($data = fgetcsv($handle, 0, ",")) !== FALSE)
    {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++)
        {
            echo $data[$c] . "<br />\n";
        }
    }

How to get this echo line to display as one line?
No matter what I have done it displays as two lines.  I even tried <nobr></nobr>

Teachers Name:
John Jones

$userid = mysql_real_escape_string($_GET['user_id']);
$sql = "select * from users where `id`='$userid' ";

$rs = mysql_query($sql);
while($row = mysql_fetch_array($rs))
{ 
echo  "<h3>Teachers Name: </h3>" . $row["first_name"] . " " . $row["last_name"]  ;  }


Thanks for your help.

I have a script that reads a .gz file into an array and prints the name of each record but will not work on larger files. Is there a way to read 1 line at a time?
Here is the code I have so far.
Code: [Select]
<?php

if ($handle = opendir('.')) {

print "<ol>";
    
    while (false !== ($file = readdir($handle))) {
if($file != '..' && $file!="." && $file!="start_update.php" && $file!="sharons_dbinfo.inc.php" && $file!="root.php" && $file!="read_directory.php" && $file!="read_dir.php" && $file!="new_category.php" && $file!="index.php" && $file!="file_count.php" && $file!="dir_loop2.php" && $file!="dir_loop1.php" && $file!=".htaccess" && $file!="Answer.txt" && $file!="Crucial_Technology-Crucial_US_Product_Catalog_Data_Feed.txt"){
$filename = $file;
$go = filesize($filename);
if($go >= 1){
$filename2 = explode("-", $filename);
$filename2 = $filename2[0];
echo str_replace("_"," ",$filename2) . ' | Filesize is: ' . filesize($filename) . ' bytes<br>';
$gz = gzopen($filename, 'r');
$lines = gzfile($filename,10000);
foreach ($lines as $line) {
$line2 = explode(",", $line);
$line2 = str_replace("," , "-" , $line2);
    echo "<li>".str_replace("," , "-" , $line2[4])."</li><br>";
}

}
}
    }

    closedir($handle);
}
?>
</ol>

Hi..,
I use below method to export data to excel.

header('Content-type: application/ms-excel');
header('Content-Disposition: attachment; filename=abc.xls');

if I run the script from the server. (http://localhost/export.php) it is work. (pop-up window if i want save or open the file)

but if i run the script from the client (http://192.168.1.5/export.php) it is not work. (nothing happen)

any idea how to solve this?

This one requires lots of up front information:

I have a page, for this example that I will call page.php. It takes get parameters, and for this example I'll call the parameter "step". So I have a URL like this: page.php?step=1 This page has a form with an action of page.php?step=1. The code on the page validates the posting information. If the information is bad, it returns the user to page.php?step=1; if it is good, it takes the user to page.php?step=2 via header( "location:page.php?step=2" ). So redirection is done by relative path, not full URLs.
This all works as expected.

Now what I've done is set .htaccess to be HTTPS for this page, via this code:

# Turn SSL on for payments
RewriteCond %{HTTPS} off
RewriteCond %{SCRIPT_FILENAME} \/page\.php [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

This works (initially). However, once you try to post the form, it just redirects back to the step=1 version of the page. I really don't know how or why that would be.

I'm not sure how else I can explain this or what other information you may have. But it's frustrating to not get a page working in HTTPS that works in HTTP. Very odd. Any suggestions? (I don't even really know the best location to figure out when/why it's redirecting back to the original page.)

I'm so sorry to ask such a "newbee question," but believe me I have been on Google for the better part of the week trying to find an answer.   I'll start with the brief question. Then I'll give an example to show what I mean. Then, I'll give the BESTEST "pseudo-code" I could come up with (to PROVE that I've really given it my best).   Question: How do I make PHP loop through a big file, make the changes line by line, and to save the resultant file.   Example: I have a 100mb text file ("animals.txt") with 500,000 lines. If any lines have the word "cat" in it, I want to add "Be careful with cats!" to the end of the line:   From this: A fish and his tank. A cat and his toy. A bird and her cage. A frog and his lilly. A cat and her friend.   To this: A fish and his tank. A cat and his toy. Be careful with cats! A bird and her cage. A frog and his lilly. A cat and her friend. Be careful with cats!   The best "pseudo-code" I can come up with is:   <?php $data = file_get_contents("animals.txt"); $lines = explode(PHP_EOL,$data);

require_once 'includes/upload.class.php';
$upload = new uploads();
$details = $upload->getFileInformation($id);

<?php echo $details['upload_desc']; ?>

then here the class.

require_once 'db.class.php';



class uploads extends database

{

   private $uploadData;

   function uploadFile() {

   public function getFileInformation($id)

   {

      $this->uploadData = $this->readData("uploadfiles", "upload_id", $id);

      return $this->uploadData;

   }


But it wont work!
      

I want my application will send a email after 10 minutes of sending another email.

In my application

A user completes registration with payment Application sends the user a payment confirmation email

Now I want to

send another email 10 minutes After payment confirmation email with welcome tips

Below is the function where for user setup .

 

public function finishUserSetup($Sub){

    if($Sub == 0){
        $subscription = SubscriptionPlans::where('identifier', '=', "Monthly")->first();
        $expiry = date('Y-m-d', strtotime('+' . $subscription->months . ' months'));
        $sub_period = "monthly";
    
    } else{
        $subscription = SubscriptionPlans::where('identifier', '=', "Annually")->first();
        $expiry = date('Y-m-d', strtotime('+' . $subscription->months . ' months'));
        $sub_period = "annually";
    }

    $this->expiry_date = $expiry;
    $this->user_type = "SUB";
    $this->subscription_period = $sub_period;
    $this->update();

    $replaceArray = array(
        'fullname' => $this->forename . " " . $this->surname,
        'subscriptionName' => $subscription->name,
        );
    EmailTemplate::findAndSendTemplate("paymentconfirm", $this->email, $this->forename . " " . $this->surname, $replaceArray);

  }

In the above function the last line of code is the one which sends a payment confirmation email to the user which is

EmailTemplate::findAndSendTemplate("paymentconfirm", $this->email, $this->forename . " " . $this->surname, $replaceArray);

I want to execute the following line of code 10 minutes after the above one

 

EmailTemplate::findAndSendTemplate("WelcomeTips", $this->email, $this->forename . " " . $this->surname, $replaceArray);

 

 

How to do that. that is running the last line of code 10 minutes after  

Some of you may have seen one of my many posts about email issues.  Some users don't get them, and I have determined it is probably because we are marked as spam.   We are a service that grades sales team members on their phone skills.  Listening to pre-recorded calls, grading and uploading them to our site, and then another part of our business looks them over and sometimes leaves a message that then get's forwarded to this persons work email.   I have determined there is ways to get marked as spam as default by not having an opt out link.  This is not an option, these sales members employer has opted in, and the emails are going to work related accounts hosted at that employer.  Also, if one of these staff members is not so bright, or disgruntled they may mark us as spam anyways.  The bottom line is that we have very little control over whether we are or are not marked as spam.   So we want to start looking into sending text messages and this is where I start to question how good of an idea this is.   First off, if it was me, and the messages where being sent to a device that my employer did not provide, I would in no way want work related text messages coming to me.  Unless there is a vested interest in getting them.  IE, I'm the boss at this place and am always on the clock.  What if you are on the bottom?  It's just a job for you.   What if it is a pre-paid device, text messages cost money.  What then?  What if they don't even have, or want a cell phone?   The short of it is this.  If I'm at a job that is just another job, and this employer tells me that I have to get these messages.  I'm going to look for another job.  I see the organizations having continuous issues and complaints from their employees.  Thus us as a business having issues keeping clients.   What am I getting into here?  What are your opinions on this matter?  What are your recommendations as to alerting users of something on our site that we can rest assured are being received 100% of the time?   Thanks!   Nick

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.

gday all!

just starting to learn php but having a liitle problem with \n forcing a line break. in my situation it simply doesnt.
looking at this what have i done wrong?
Code: [Select]
echo "<div class=\"imgcontainer\"><a href='$row[filename]'  rel='shadowbox[thingo]'><img class= 'thumbnail' img src='$row[filename]'/></a><div class=\"thetext\">Artwork: $row[name]\nArtist:$row[artist]</div></div> ";
Thanks

I am sorry even i didn't say hello to forum but i need this snippet very urgently. i have Zero knowledge of PHP but unfortunately i need a small code as follow.

Hi, here the bit of code:

Code: [Select]
echo 'You\'ll be redirected in'; include('script.html'); echo 'secs. If not, click <a href="visit.php">here</a></div>.';
this is being displayed on 3 lines I want to have it all on 1 line, how is this done?
(script.html is a javascript countdown clock)

thanks

Code: [Select]
$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= $row['Field'].",";
$i++;
}
}
$csv_output .= "\n";

$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j].", ";
}
$csv_output .= "\n";
}

print $csv_output;
I'm using the above to get a csv output in my browser, but it appears as a string of text
eg
a1,a2,a3,a4,b1,b2,b3,b4,...

I'd like it to appear as
a1,a2,a3,a4
b1,b2,b3,b4
c1,c2,c3,c4

Any ideas how?
