PHP - Using The Exec() Function To Contain An Imagemagick Command

how do i enable exec() in php.ini? where is php.ini? cant find it in the directories in my site.

Hi, I'm trying to build a 'simple' page to improve a process where I work.   I'm wanting to do this.   Read either the last line, the last 10 lines, or something I decide on from a log and display the output in table rows and columns.    I've done this before with loops and db query's, but don't know how to approach it using php only as this is the first time I'm using it.   So right now I have this in a table but it will only display one row.   <tr><td colspan="5">

I have a PHP script containing the function exec which works fine in PHP 4 in IIS 7 on Windows 7. However this function does not work in PHP 4 in IIS 5 on windows server 2003. But I have to make it work there because that is what we have on our web server.
Can someone provide a solution?

Hey guys I usually code in C and I started looking into PHP which I think is pretty good. I'm wondering if there's a function that can be used to execute a command from a remote server on my local machine???

As example if I'd like to have a PHP page/script running on my server which when logged onto would display me a page with buttons like "PING, NETSTAT, IPCONFIG, TRACERT" and when clicked on it would exec those commands but not on the server but from my machine??? So that I would get the PING from my local machine to google.com instead of from the server to google.com

??? making any sense ??? thanks

Hello all

 

I'm new to this forum.

I've been struggling on this problem for a few days now.

I’m writing a script to automatically push code to a git server.
I’m using php and running the script via the command line.
After asking the user to enter the branch and commit message, the following code runs:
 

exec(‘git config user.name "’ . $userName . ‘"’);
exec(‘git config user.email "’ . $userEmail . ‘"’);

exec('git checkout -b ’ . $branch);
exec(‘git add --all’);
exec(‘git commit -m "’ . $message . ‘"’);

exec('git push origin ’ . $branch);

 

When running the last command, the script stops and asks for a user name, then a password.
How can I enter that username and password via the script?
I don’t want to have to type in the user name and password each time.
As I said, I've been stuck on this for 2 days now.

I tried other forums, searching the net.

I'm frustrated...

Thanks in advance.
Have a lovely day.

I have a line of code that has been working for over a year, then two days ago it failed in a few areas on my site and I hadnt made any changes. I contacted the host and there was no server updates etc.

Its a php/imagemagick issue, basically the "widthxheight^    -   Minimum values of width and height given, aspect ratio preserved" command does not work and fails to import the image at all when I add ^ to my code.

I need it though and im getting fustrated, for now ive changed my code to:
exec("convert $path1 -thumbnail 200x180 -colorspace rgb -gravity center -extent 170x150 $path2");

which works ok but is not spot on like it was before, what I really want is

exec("convert $path1 -thumbnail 170x150^ -colorspace rgb -gravity center -extent 170x150 $path2");


What ever I do I cant get ^ to work anymore but oddly all other imagemagick commands are fine. 
 

Hi all

I am trying to resize an image using imagemagick but it won't let me use the below code as it shows a security error 'exec() has been disabled for security reasons':

Code: [Select]
$scale = '158x158';
$go = WEB_UPLOAD.'/test/images/'.$image;
$stop = WEB_UPLOAD.'/test/images/'.$image_medium;
exec("/usr/bin/convert $go -resize $scale\> -quality 100 $stop") or die("Error creating 158 x 158 image.");
unset($scale, $go, $stop);

How do I write the code that resizes the image without using the exec function?

Many thanks for you help!

Hi all

I need to re-write the below code so that it doesn't use the exec function:

Code: [Select]

$scale = '74x74';
$go = WEB_UPLOAD.'/test/images/'.$image;
$stop = WEB_UPLOAD.'/test/images/'.$image_small;

exec ("/usr/bin/convert $go -resize $scale\> -quality 100 $stop") or die("Error creating 74 x 74 image.");


Many thanks for your help.

Hi all

I'm using MAMP and trying to install ImageMagick.

Is there a way to test if it is correctly installed when using MAMP?

Hi all

I have created the below script to resize my images and it works fine for landscape images but if you select a portrait image it saves it as a landscape image. How do I modify the script so it keeps the same aspect ratio?

Code: [Select]
copy($_FILES['image1']['tmp_name'], WEB_UPLOAD."images/adverts/test/".$_FILES['image1']['name']) or die("Error uploading image.");
$ext = strtolower(substr($_FILES['image1']['name'], strrpos($_FILES['image1']['name'], ".")));
$rand = rand(1, 100000000000000);
$name = $rand . $ext;
$image_small = $rand . $ext;
rename(WEB_UPLOAD."images/adverts/test/".$_FILES['image1']['name'], WEB_UPLOAD."images/adverts/test/".$name) or die("Error renaming image.");;
$go = WEB_UPLOAD.'images/adverts/test/'.$name;
$stop = WEB_UPLOAD.'images/adverts/test/'.$image_small;
exec ("/usr/bin/convert $go -resize 10%\> -quality 100 $stop");
unset($scale, $go, $stop);

Many thanks for your help.

Here is the code I have right now:

<?php
header('Content-type: image/png');

$grey = new ImagickPixel('#ebebeb');
$orange = new ImagickPixel('#0f92d6');

$image = new Imagick('assets/lop.png');
$layer = new Imagick('assets/lop-base.png');
$layer->thumbnailImage(200, 0);
$image->thumbnailImage(200, 0);

$layer->paintOpaqueImage($grey, $orange, 100);

// Place layer on image
$image->compositeImage($layer, Imagick::COMPOSITE_SOFTLIGHT, 0, 0);

// Let's merge all layers (it is not mandatory).
$image->flattenImages();

echo $image;

?>

It's putting the layers on top of eachother very nice. The thing is is that this involves some heavy shading at times depending on the bunny breeds.   Here is what the base image ($image) looks like:     And here is what the overlay ($layer) looks like:     This is what the outcome looks like versus the intended result:       I've tried almost all of their composite constants.. I can't figure out how to do this or the best way of going about it. Because the colors are going to be dynamic throughout the site so I can't just save a .png of every color combination.. and there will be more colors layered on top of eachother like markings/patterns/etc.   Thanks for any help!

Hi,

Very new to PHP and am enjoying learning the ins and outs etc, but while creating my mam a website, ive ran into a problem while uploading, resizing and saving the file to my web host. Initially i used imagecreatefromjpeg, but this was taking too much memory up, so opted to use imagemagick. All of the features work apart from the file getting saved to the uploads directory on my web space. They always get saved to the root. If someone could help i would be very grateful. The code ive got currently is:

<?php

// If the form has been submitted do this
if(isset($_POST['submit'])) { 

// Temporary upload image name
$original_image = $_FILES['photo']['tmp_name']; 

// Get the image dimensions
$size=GetImageSize( $original_image );

// Name to save the image as - in this case the same as the original
$new_image = $_FILES['photo']['name'];

// Maximum image width
$max_width = "600";

// Maximum image height
$max_height = "300";

// Resize the image and save
exec("convert -size {$size[0]}x{$size[1]} $original_image -thumbnail $max_widthx$max_height $new_image");

echo "File uploaded<br>";

echo "<img src=\"".$new_image."\">";
}

?>

Hopefully someone could help

Many thanks,

Matk.

(1) What does this actually do? (compress it?)

$image = imagecreatefromjpeg("image.jpg");
header('Content-Type: image/jpeg');
imagejpeg($image);

By using this rather than displaying by using www.site.com/image.jpg it reduces file size of an image from 2.5mb to 0.5mb !!

(2) ImageMagick can't get these results. Am I doing something wrong? If I change the pixel size of an image in ImageMagick then I can reduce its file size, but (1) above reduces file size regardless of changing pixel size.
