The 10 best PHP image manipulation libraries in 2014, 2014php

Thomas Boutell and many developers created a graphics software library known as the GD graphics library for Dynamic graphics calculation. GD provides support for many programming languages ​​​​such as C, Perl, Python, PHP, OCaml, etc. In addition to generating HTML output, you can also use PHP to generate many programming languages ​​​​like PNG, JPEG, GIF, WBMP , and graphics file formats such as to compile php.

In this article, you will learn the 10 best PHP graphics calculation libraries that can help you simplify your work. These graphics calculation libraries will help you in your graphics-related work. Some of the best PHP graph computing libraries for developers are introduced below:

　1. Imagine

This image processing library is an object-oriented PHP library built with PHP 5.3. By using this library, you can easily perform tasks such as cropping, resizing, and placing filters on images. In order to produce a specified RGB code value and object transparency percentage, the library's color class has two parameters in its constructor.

　2. Php Graphic Works

This library was created to perform image processing on the server side. Using this image library allows you to perform complex image processing in a simple way. Operations that can be performed on images include rotating, cropping, scaling, stretching and flipping. And you just do it with a bunch of code.

　3. Zebra Image

This lightweight and object-oriented image processing library is built in PHP. The image formats it supports include JPG, GIF and PNG. It has the unique ability to convert one format into another after every action.

　4. Php5 Image Manipulation

This fully object-oriented image processing library is available for PHP and GD2. It is considered an extension of the PHP-image project. This object-oriented image processing library provides various ICO image file types such as PNG, GIF, PSD, JPEG and ICO. In addition, it can output various image file types supported by GD2.

　5. Dynamic virtual image generation

This is a free PHP script library through which you can generate images of any size and color. Additionally, you can enter text on top of the image.

　6. WideImage

　Wide Image is also considered an object-oriented library for image processing. Using this library, you can perform general operations such as processing, loading, saving images in image formats, etc.

　7. Image Cache

This lightweight PHP class is used to move, compress and cache images in the browser. It then returns the new source of the image printed in the image tag. You can use this library by setting various options, such as base URL, directory, etc.

　8. Image Workshop

This is a free-to-use PHP class considered a layer-based image editing software. It allows you to overlay multiple layers and have the ability to perform functions such as placing one image on top of another, moving, resizing, cropping, writing, rotating, overlaying, etc.

　9. Asido

This is a PHP library with rich functions for operating images, suitable for any running environment, such as Magick Wand, GD2, and Image Magick. It supports both PHP4 and PHP5.

　10. PhpThumb

In addition to supporting various popular image formats, this PHP library also accepts all image resource types. Using this image manipulation library, you can rotate, crop, and watermark images. In addition to this, you can also define the pixels of the image.

How to output images in php gb image library

Calling example: Output the two Chinese characters "China" through GD
example.php

//Header("Content-type: image/gif");
$im = imagecreate(400,300);
$bkg = ImageColorAllocate($im, 0,0,0);
$clr = ImageColorAllocate($im, 255,255,255);
$fnt = "d:/winnt/fonts/simhei.ttf" ;
include("gb2utf8.php");
$str = gb2utf8("China");
ImageTTFText($im, 20, 0, 10, 20, $clr, $fnt, $str );
ImageGif($im);
ImageDestroy($im);

php+mysql image insertion and display operation code

If you save the image stream, the database will be very large. It is recommended to save the path. Put the images in a unified directory for easy management.
To save is to insert the field. Use the relative path of vchar to save the field.
To read is to query. Then put the database into the array,
display and that’s it

function uploadPhoto ($file) {

$this-> ;result = false;
$this->error = false;
// -- save parameters
$this->_file = $file;
//get path
$ this->createUploadDir();
$this->_destination=SystemProperties::$UPLOAD_ROOT_PATH['photo'];
//if (!is_null($allowed)) { $this->_allowed = $allowed; } else { $this->_allowed = array('jpg','jpeg','gif','png'); }

// -- check that FILE array is even set
if (isset($file) && is_array($file) && !$this->upload_error($file['error'])) {

// -- cool, now set some variables
$fileID=$this->_IDGenerator->getNextId('IMAGE');
$fileExt=$this->ext($file['name']);
$ fileName =$fileID.'.'.$fileExt;
$this->createFileDir('image',$fileName);
$fileTmp = $file['tmp_name'];
//$ fileSize = $file['size'];
//$fileType = $file['type'];
$fileError = $file['error'];

// -- update name
$this->_name = $this->_destination.$fileName;
// -- it's been uploaded with php
if (is_uploaded_file($fileTmp)) {
/ / -- where to put the file?
$filePath=$this->_fileUtil->getFilePath($fileName);
$output = $this->_destination.$filePath['filePath'] ;
