PHP implementation to receive binary transfer of images

This article mainly introduces the implementation of PHP to receive binary transfer to the image of the method, combined with examples of PHP files, directories and graphics operations related skills, the need for friends can refer to the following

Specific as follows:

Here to implement PHP to receive binary flow into the picture, the picture class used imageupload.php as follows:

<?php/** * Picture class * @version 1.0** PHP recognizes only application/x-www.form-urlencoded standard data types by default. * Therefore, the type such as text/xml or soap or application/octet-stream content can not be resolved, if the $_post array to receive will fail! * So keep the prototype and give it to $globals[' Http_raw_post_data ') to receive it. * There is also a php://input that can be implemented this feature * Php://input allows to read the original data of the POST. Compared to $HTTP _raw_post_data, it brings less pressure to memory and does not require any special php.ini settings. Php://input and $HTTP _raw_post_data cannot be used for enctype= "Multipart/form-data".  */class imageupload {Const Root_path = './';  Const FAIL_WRITE_DATA = ' FAIL to WRITE DATA ';  No data flow Const NO_STREAM_DATA = ' The post data is empty ';  The picture type is not correct const NOT_CORRECT_TYPE = ' Not a CORRECT image type ';  Cannot create file const Can_not_create_file = ' Can not ' create file ';  Upload image name public $image _name;  Picture save name public $save _name;  Picture save path public $save _dir;  Directory + picture full path public $save _fullpath; /** * constructor * @param string $save _name Save Picture name * @param string $save _dir Save path name */Public function __construct ($sav E_name, $save _dir) {//set_error_handler ($this->error_handler () ); Set Save picture name, if not set, randomly generate a unique file name $this->save_name = $save _name?    $save _name:md5 (Mt_rand (), uniqid ()); Set save picture Path, if not set, use year/month/day format for directory storage $this->save_dir = $save _dir?
