PHP - Reduce Image File Size Using Php

i want to display the size of a file but i round it off to the nearest kb.

I am using...
($_FILES["file"]["size"]/1024/1024)."mb"

i am geting it return something like this....
1.0313243865967mb
and i want it to be more like
1.03mb

any idears???

                                         $file="../myclients/clients/".$company_name."/Download/".$file_name;
                $size = filesize($path); // not working

i try with  function  also

       function formatbytes($file, $type) 
    { 
        switch($type){ 
            case "KB": 
                $filesize = filesize($file) * .0009765625; // bytes to KB 
            break; 
            case "MB": 
                $filesize = (filesize($file) * .0009765625) * .0009765625; // bytes to MB 
            break; 
            case "GB": 
                $filesize = ((filesize($file) * .0009765625) * .0009765625) * .0009765625; // bytes to GB 
            break; 
        } 
        if($filesize <= 0){ 
            return $filesize = 'unknown file size';} 
        else{return round($filesize, 2).' '.$type;} 
    } 

echo formatbytes($file, "KB");



uploaded file size is 488 kb   

but it showing   "unknown file size"

please help me.

I need to check a file's size with php and ssh.  Everything I've seen online for remote files uses curl and port 80.  I'll be checking a LAN computer that isn't running a webserver, but is running an SSH server.

How can I do this?

I've tried this:

Code: [Select]
<?php
$tomorrow = date ('n-j-y');
echo system(ssh root@192.168.2.169 ls -lah "/MacRadio X/WMIS Logs/WMIS $tomorrow Log" | awk {print $5});
?>

but it didn't work.  I got a T_VARIAABLE error.  This was the same command I used right from the command line, and it worked.

I'll also need to add a check to the file size, and if it's less than 175K, send me an email...but I'll work on that after I have the first part working.

Thanks!

What's the maximum file size I can upload through a regular form ? If it's server dependant, how do I find out my max ?

I tried to handle a 550MB file (on localhost) - I only wanted to show the filename, but it hung up for about 10secs, then returned nothing.

I've got a basic form for users on the site to fill out a form and upload a single image which is resized and saved to a directory on the server. I've tried the form numerous times and with images usually under 1MB the form successfully submits, data is queried and the image uploaded is resized and saved. However, recently I tried uploading larger sized images (1.2mb, 2.4mb, 3mb) and the script would seem to break. It wouldn't query any information, save any images, etc.

If you check my code attached, I have errors ready to output at all levels and not even any errors show up. When I hit submit after attempting to upload a larger file usually over 1MB, the page refreshes back to PHP_SELF as if it submitted but returns absolutely no message, alert or error and the form which was on the page is now gone.

I checked my PHP.ini file and my max file size upload is set at 32mb. Is there anything else with file size restrictions that I could be missing that is allowing this script to crash without even sending me any errors?

I have a simple script which records search terms and writes them to an external file. I would like to limit this file size.

The Use:
I have a search page where people can search for PDF files. I would like to have a 'cloud tag' or list of the most recent terms searched at the bottom of the page.

Here is my script which works beautifully:

<?php

$pattern = "/filetype:(\w+)/";   // filteype:(wildcard for word) to grab the file extension along with the word filetype:

if ( $_GET['q'] == "" ) {
$term = "";
} else {
       $term = preg_replace("$pattern", '', $_GET['q']); // get rid of the filetype parameter
}

$searched = $term . ", ";
$fopen = fopen("searched.html", "a");
fwrite($fopen, $searched);
fclose($fopen);
?>


The above code grabs the search term when the SERP page is opened, and writes it to a file. I will later use phpInclude to put the contents of that file on the bottom of my search engine page.

The problem is that after a million searches, this file will be huge!

Question:
How can I limit the file size and organize these search terms so that the most recent ones appear on the page?

Hi Chaps,

I'm using readfile to force the download of a file:

set_time_limit(0);

$file = 'monkey.gif';

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
    exit;
}
flush();


And this works fine, however, I do have some software installation files that could be downloaded (these are in excess of 280Mb).
I have checked php.ini:
Quote

memory_limit = 128M
post_max_size = 300M


But Internet Explorer hangs and then crashes.
Is there a way to allow big files to download using this method, or is there another way of forcing the download, without php 'reading' the file first?
I'm guessing that the problem lies with the memory_limit being smaller than the file size. Is it a good idea to increase the memory_limit to eg. 280Mb?
Cheers

Ok so I have someone needing me to write a php page(s) to basically check the current size of a file in a directory and display the current size and max allocated size then create a dynamically changing image to reflect those parameters(i.e. pise chart, bar graph, etc.) all called to an intranet page.

I work at a business where we upload OS images to a server file but that file is only allocated so much space. The problem we are running into is that we do not know when the space is full until all of our uploads fail.   We are attempting to create a visual representation of that space so that we know when to purge the space of the old temporary images.

I dont even know where to start on this .. would someone please point me in the direction of some code that would get me started on building this project? I have exhausted my efforts on Google and other PHP pages.. I am new to PHP so I may already be in over my head but I am adventurous and will try anything.

Thanx in advance

hi,

whats the best way to print labels.
I have already tried the script from fpdf.de

but i can not get my dot matrix printer (dot matrix is needed for this purpose)
the correct layout.

Its continuous paper, with size 110 height x 62mm width (for each label).
I am not able to select a self-adjustable paper-size. so i hope to solve this
with PHP / PDF if possible.

anyone have experience with this?
cheerz!!

Works great, except when I upload a 400kb or larger file... Is there some kind of limit to the ability of the GD library?

Anyone have a work around?

Thanks!

What file size is allowed with this code?

if (@$_POST['submit'] != "") {
    $allowed_ext = array("gif", "jpeg", "jpg", "png", "pdf", "doc", "docs", "zip", "flv", "mp4");
    $extension = end(explode(".", $_FILES["file"]["name"]));
    if (($_FILES["file"]["size"] < 524288000) && in_array($extension, $allowed_ext)) {

how to put code for check file size before upload  in the if issertfile .the file is in format pdf or docs 

 $targetDirg= "folder/pda-semakan/gambar/";
 if(isset($_FILES['gambar'])){
     $fileNameg = $_FILES['gambar']['name'];
 $targetFilePathg = $targetDirg . $fileNameg;
 //$main_tmp1 = $_FILES['surat']['tmp_name'];
 $moveg =move_uploaded_file($_FILES["gambar"]["tmp_name"], $targetFilePathg);
 }  
         
 

 

I am trying to use the GD library functions to reduce the size and ppi of images.  Unfortunately my server does not support imagick, which can do this,  but I have worked out a way to do the job, except that the process always makes the image 75 ppi.  I would rather have some control over the pixel density.

Can anyone suggest an answer please?

Here is my code......

Code: [Select]
<?php
$filename = 'my.jpg';
$size_multiple = .5;//change to suit dimensions wanted
header('Content-type: image/jpeg');
list($width, $height) = getimagesize($filename);
$new_width = $width * $size_multiple;
$new_height = $height * $size_multiple;
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
imagejpeg($image_p, null, 100);
?>

I've got a typical form with an input type="file" for users to upload photos to my site (2mb max to be exact). If you view my code below, you'll notice that I set a variable as the uploaded file's size, and a variable for the max file size I want in bytes. When making sure that the uploaded file's size is LESS than the limit size I set, it should push an error.

However, I've noticed that my variable $uploadSize that is supposed to grab the upload file size is only returning "0" (zero). I've tried var_dump($_FILES) to see what was going on and it shows the array with the proper name of the uploaded file, etc. but the file size returns 0.

So any file size I upload will bypass my test to see if the file size is less than the limit size. I've tested uploading images 2mb or less and the photos have successfully been queried, moved and resized. However, if I try and upload images LARGER than 2mb, the form still queries all the inputted data into the database but the image isn't successfully moved.

I've used this same form and approach on a previous project and I didn't have any trouble. Can I get your guys' eyes on this and see if I'm missing anything small?

Code: [Select]
<?php

if(isset($_POST['submit'])){

// ------------------------------------------------------------- //

// A.   SET VARIABLES
// A1.  set variables for inputted data
$first = filter_var($_POST['first'], FILTER_SANITIZE_STRING);
$last = filter_var($_POST['last'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_SANITIZE_STRING);
$email2 = filter_var($_POST['email2'], FILTER_SANITIZE_STRING);
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$description = filter_var($_POST['description'], FILTER_SANITIZE_STRING);

// A2.  set variables for uploaded submission
$uploadPath = $_FILES['uploadFile']['tmp_name'];
$uploadSize = $_FILES['uploadFile']['size'];
$uploadLimit = 2097152; /* 2mb max file size */

// A3.  create error array
$errors = array();

// ------------------------------------------------------------- //

// B.   VALIDATE FIELDS  
// B1.  validate required fields
if (empty($first)){
array_push($errors, 'first');
}
if (empty($last)){
array_push($errors, 'last');
}
if (empty($email)){
array_push($errors, 'email');
}
if (empty($email2)){
array_push($errors, 'email2');
}
if (empty($name)){
array_push($errors, 'name');
}

// B2.  validate emails
if ($email != $email2){
array_push($errors, 'emailmismatch');
}
if (!filter_var($email, FILTER_VALIDATE_EMAIL)){
array_push($errors, 'invalidemail');
}

// B3.  validate uploaded image file size
if ($uploadSize > $uploadLimit){
array_push($errors, 'filesize');
}


// ------------------------------------------------------------- //

// if no errors, continue query
if (sizeof($errors) == 0){
// continue query
}

}
