PHP - Output Csv Straight To Browser

I have an array with 192 items in it (0-191) and I want to rearrange them into a multidimensional array with 24 sets of 8.

If I wasn't very clear there, here's an abbreviated version of what I want:

$arr1 = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23);

$arr2 = array(array(0, 1, 2, 3, 4, 5, 6, 7), array(8, 9, 10, 11, 12, 13, 14, 15), array(16, 17, 18, 19, 20, 21, 22, 23));

Thank you in advance!

I've got a site that requires the user to follow a well-defined workflow, corresponding to a sequence of pages. You'll have the right idea if you think of a store where the user selects items, then chooses a delivery method, then pays (although the site's actual purpose is somewhat different than that).

I just tracked down a puzzling logical failu a user followed the workflow up to a certain point, then opened a new browser window, pointed it to the site, and started a second workflow. The site stores information about the user's activities in session variables, and the two windows shared a single session, so the site got tremendously confused about what the user was doing.

Given the site's design, visiting the site in two windows at once is a legitimate thing for a user to do. I'm darned if I see how I can accommodate it, though.

Other designers must have dealt with this problem many times. What ways of solving it have been found effective?

In this case, the simplest and most effective solution would be to create a new session for each window in which the user visits the site. Is there any way to do that?

Well I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script:

<?PHP
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
$RepeatIt = -1;
for($g=1; $g!=$RepeatIt+1; $g++)
{
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***

$ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>";
echo $ScanMessage;

***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
}
?>

At the moment it's returning:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.:

So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line.

Any suggestions?

Thanks.

Quotation marks are confusing me.   What do you guys use when it comes to quotation marks?   In HTML attributes and throughout the bodies of my web pages, I use the HTML entity (&quot;). For example:

<a href="" title="Read &quot;Article Name&quot;">

<p>In his new book, he says: &quot;This is a quote.&quot;</p>

I thought that this is the best practice.   However, today, I read that it's perfectly safe to use straight quotes (") in the body, and that I should use the HTML entity only in HTML attributes.   Is that correct?   But what if I want to use curly quotes in the body instead of straight quotes? Should I always use the HTML entities for curly quotes (&ldquo; and &rdquo;), or can I also safely use the characters (“”)?   I heard that straight quotes are safe in all browsers, even if you don't specify the character set of your web pages, but that curly quotes are only safe if you specify the character set or if you use the HTML entities.   Is that true?   And what about the <q> tag? Apparently, it's compatible with all browsers but they treat it differently.

I'd like to use an application that's not browser based, on Internet Explorer. I've read somewhere that this is possible with a PHP script, but which one? If you can get me on the right track, I'd really appreciate it. Cheers.

How do I got about outputing one row that can only hold one value? Any reason why the function below doesn't work?

Code: [Select]
<?php
include "database.php";
session_start();
$name = $_session['outname'];

function output_wins(){
$sql = 'SELECT * FROM account_info WHERE username ="' . $name .'"';
$result = mysql_query($sql);
$wins = mysql_fetch_array($result);
echo $wins['win'];
}



output_wins();

?>
Is there an easier way I can output this one row?

Hey folks,

I have made a cart for buying drinks. I also made an sql database. But when I click on the email button, I receive an email but only with the id of the products. I would like to have an output with the id of the product, but also the name of the product ( the name of the column in sql is also 'name')

this is my code and you can check it out on  http://fhcs.be/cart-demo3/

thanks in advance

I have created a PHP page where the contents are pulled from DB. Is there a way that I can save the file with the output and stylesheet to PDF with a click of a button.

Team

   I tried to create csv output ( every value in double quotes) in my php using below function

if($generate_csv){
    generateCSV($custom[0]['details'], date('Y_m_d_')."check".".CSV", $detail_headers);
}

function generateCSV($data, $filename) {
  $file = fopen("/local/myloc/populated/".$filename,"w+");
  $i = 0;
  foreach ($data as $line) {
    $fields = array();
    foreach ($line as $k => $v)
    {
        $fields[$k] = $v;
    }
    if( $i === 0 )
    {
     fputcsv($file, array_keys($fields) ); // First write the headers
    }
    fputcsv($file, array_values($fields));
    $i++;
  }
  fclose($file);
}

I got below output with one issue (There is a blank at the end of each value)

Date,time,Device,lable,throughput_read,throughput_write
"11/19/2020 ","00:00 ","audigysg36s6101 ","host17 ","0,00 ","0,00 "
"11/19/2020 ","00:00 ","audigysg36s6101 ","host1 ","0,00 ","0,00 "
"11/19/2020 ","00:00 ","audigysg36s6101 ","host18 ","0,00 ","0,00 "

 

Could you please help me to resolve this issue

Hi all,

Is there a simple way to log the command output of a linux console?

This command locks up my screen. It is a screen on an Aastra IP phone.

$command = 'logsave /var/www/html/aastra/test.log ls';

shell_exec($command);


Thanks!

Hi. I found a code online but unfortunately, the data is retrieved via variables. How can i convert this code to retrieve the data from database instead. Thank you in ADVANCE!

Code: [Select]
var members = [
    ['Steven B. Ayres', '1911-1913', 'New York', 'Independent Democrat', '1861-1929'],
    ['William Augustus Ayres', '1915-1921 1923-1934', 'Kansas', 'Democratic', '1867-1952'],
    ['William Hanes Ayres', '1951-1971', 'Ohio', 'Republican', '1916-2000']
];

I have a function which is listing my directories w/ files (Images) in them.
<?php
function sortDirectory($path = 'images') {  
  $ignore = array('.', '..', 'index.php');
  $folder = array();
  $dh = @opendir($path);
  while (false !== ( $file = readdir($dh) )) {
if (!in_array($file, $ignore)) {
  if (is_dir("$path/$file")) {
$folder[$file] = sortDirectory("$path/$file");
  } else {
$folder[$file] = "$path/$file";
  }
}
  }
  closedir($dh);
  ksort($folder);
  return $folder;
}

function getDirectory($folder = array(),$level = 0) {
// Set which extensions should be approved in the XML file
  $extensions = array(  'jpg', 'JPG',  'png', 'PNG',  'gif', 'GIF',  'bmp', 'BMP');
  $spaces = str_repeat('&nbsp;', ( $level * 4));
  foreach($folder as $file=>$path) {
if (is_array($path)) {
  echo "<strong>$spaces $file</strong><br />";
  getDirectory($path, $level+1);
}
else {
if ( in_array( substr($file, -3), $extensions ) ){
  echo "$spaces <a href=\"$path\">$file</a><br />";

Im trying to get it to write an xml file in this fashion
Code: [Select]
<?xml version="1.0" encoding="utf-8" standalone="yes"?>

        <image>file1.jpg</image>       
    </pic>

    </pic>
    <pic>
        <image>file2.jpg</image>       
    </pic>   
</dir2>but I cannot seem to get a grasp on this simplexml for more than 1 directory - any help appreciated.?

Hi,

This script lists all the contents of the dir it is placed in bar itself. Perfect for what I need. However, I want to output the results as xml and being new to php I really don't know where to start.

<?php
foreach (new DirectoryIterator('.') as $file) {
     if ( (!$file->isDot()) && ($file->getFilename() != basename($_SERVER['PHP_SELF'])) ) {
            echo ($file->isDir()) ? "(Dir) ".$file->getFilename() : $file->getFilename();
         }
}
?>

I'd be thankful for the help

Thanks in advance.
