How do you get PHP codes for writing on an image?
You can use the GD extension for PHP to edit image files.
if i got your question right, you mean "what are php tags?" your should write PHP codes between <?php ... ?> where ... should be replaced by codes that you need. But if you mean "what are php codes?": there are some default codes that you may find them on php.net, and the other part is codes (Functions or classes) that other programmers develops..
I have had a lot of experience with image modification modules with PHP. In order to perform image manipulation in PHP you need an image processing module installed such as GD2 or imagemagik. GD2 comes with PHP and can be installed fairly easily if it is not already installed. You can follow the PHP GD manually for the usage of these functions.
Image creating and manipulating in PHP can be done with multiple libraries, some officially supported by PHP and some made by third parties. A common library, especially for developers new to image libraries, is the GD package. You must include the library you wish to use upon installation of PHP (if it is officially supported), or manually include the library into your scripts.
If you can get the image url then just assign it to a php variable say: $image = (See related Link) Then you just have to add '$image' to the insert statement of your sql query Note: It would be better to store the folder path where your image is stored. That way your image will not be lost if your site moves to another server.
You upload the image in HTML using a form that includes the following field <input type="file" name="fileUpload" /> After the form is submitted, you can access it with the $_POST variable as $_POST['fileUpload'] http://www.tutorialsscripts.com/free-php-scripts/file-and-directory-script/image-upload.php
It depends what Database you are using. I personally use MySQL so will explain how you would do it using MySQL. You would have to create the MySQL database. I would store the image URL rather than the actual image. Then call it using PHP and a MySQL query. For Example: $sql = "SELECT * FROM Images WHERE Img_Name = 'img1'"; $query = mysql_query($sql); $array = mysql_fetch_array(query); then you would call it into HTML like…
If you are looking for a guide to get started with PHP, then w3schools.com is probably where you want to be. php.net can also be useful but is often considered more complicated. tizag.com's tutorial is sometimes good as an other explanation for some things that w3schools may have missed without being too complicated. Besides, you can refer to phpmatters.com that offer the PHP knowledge from the most basic aspects including the simple codes and PHP-based…
To learn PHP it is best to read a few tutorials and then start trying out the things you read about. For instance, make a program that does some calculations and then prints the result on the screen. A good tutorial to start with can be found on: http://w3schools.com/php/default.asp or http://www.geekatude.com/PHP or http://php.net or http://www.phpmysqlbrain.com You can install the things in your local system , and then by referring the above websites try to write…
The difference between "scripting" and "programming" is largely one of semantics; they're essentially the same thing. A purist is more likely to call writing in a usually interpreted language (such as PHP) "scripting" and writing in a usually compiled language (such as C) "programming". But either way, you're writing a set of instructions for the computer to follow, and some "scripts" can be as (or more) complicated than many "programs."
here is a little script that should do the thing: $save = "yourfolder"; $modwidth = 100; header('Content-type: image/jpeg') ; list($width, $height) = getimagesize($file) ; $modper = $modwidth/$width; $modheight = $height * $modper; $tn = imagecreatetruecolor($modwidth, $modheight) ; $image = imagecreatefromjpeg($file) ; imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; imagejpeg($tn, $save, 100); it is called GD script (used to make images via PHP)
