PHP - Output Buffering Help Needed.

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.

   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

I have a function which is listing my directories w/ files (Images) in them.
<?php
function sortDirectory($path = 'images') {

  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 />";
  }

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']
];

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!

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.

I'm not getting any errors but I"m not getting the output I'm expecting. When it gets the characterIDList values if there is a value for that field it needs to take that value then explode it and get the ID and characterName of each of the values so say the value inside of characterIDList was 2,3 then for each of those values it would find the characterName and ID of the value and be able to put each of them as a LI inside the UL.  I was hoping I could have the charactersQuery separate because I use it for the dropdown.

Code: [Select]
$newsQuery = "
    SELECT
        news.categoryID,
        news.newsTitle,
        news.newsPicture,
        news.content,
        news.characterIDList
    FROM
        news
        LEFT JOIN categories
            ON news.categoryID = categories.ID
    WHERE
        news.ID = '" . $newsID . "'";
$newsResult = mysqli_query ( $dbc, $newsQuery ); // Run The Query
echo $newsQuery;
$row = mysqli_fetch_array ( $newsResult, MYSQL_ASSOC );
$characterIDList = $row[ 'chracterIDList' ];

$characterIDList = explode(',',  $characterIDList);

foreach($characterIDList as $value){
    $charactersQuery = "
        SELECT
            ID,
            characterName
        FROM
            characters
        ORDER BY
            characters.characterName";
    $charactersResult = mysqli_query ( $dbc, $charactersQuery ); // Run The Query
}

Code: [Select]
<div class="field required">
            <label for="charactersDrop">Characters Involved</label>
            <ul id="characterList" style="list-style: none; margin-left: 195px;">
            <?php
              mysqli_data_seek( $charactersResult, 0 );
              while($row = mysqli_fetch_array ( $newsResult, MYSQL_ASSOC )) {
                if ($row['characterName'] == NULL  ) { 
                    
                } else {
             ?>
                    <li characterID="<?php echo $row['ID']; ?>" characterName="<?php echo htmlentities( $row['characterName'] ); ?>"><?php echo htmlentities($row['characterName']); ?> <a href="#">Remove</a></li>   
             <?php }} ?>
            </ul>
            <select class="dropdown" name="charactersDrop" id="charactersDrop" title="Characters Dropdown" style="margin-left: 195px;">
                <option value="">- Select -</option>
               <?php
                    mysqli_data_seek( $charactersResult, 0 );
                    while ( $row = mysqli_fetch_array ( $charactersResult, MYSQL_ASSOC ) ) { 
                        print "<option value=\"".$row['ID']."\">".$row['characterName']."</option>\r";
                    }

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.

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'];

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
