PHP - Including Library Classes
Suppose you have a ENORMOUS library class where you have collected - perhaps - validation functions.
Suppose you also have a small php script that you wish to use one of these validation functions in. So, you include the class. Is there a lot of "overhead" involved in including a huge class of which you use only one function? Similar TutorialsI've been spending long hours learning about classes and their magic methods. I just came across a tutorial which showed a constructor like this:
class Device {
//...
public function __construct(Battery $battery, $name) {
// $battery can only be a valid Battery object
$this->battery = $battery;
$this->name = $name;
// connect to the network
$this->connect();
}
//...
}
the Battery part instantly caught my attention. Here had previously made a Battery class (and a more complete Device class) but the next thing he did really caught my interest:
$device = new Device(new Battery(), 'iMagic'); // iMagic connected echo $device->name; // iMagicwhat the hell is going on here? Is this another way to include the methods and properties of one class into another class, in order words is this the same thing as: class Device extends BatteryI don't think so because this new Battery() thing looks more like its creating an object inside the Device object. Previously the only way I could to that was to type $battery = new Battery() inside one of my methods. But this looks like hes doing something different. Can anyone explain whats going on here? The whole tutorial is he http://code.tutsplus...-php--net-13085 in the main Device method he has a premade $battery variable to hold the Battery object. Sometimes I have multiple classes containing functions which I'd like to include in my main class. I can only extend one class, so I usually extent a class containing only properties, no methods. I still don't know what difference making that info class abstract is, I'd appreciate if anyone could tell me. Also I'd love to know what the point in static methods is. I've never used them because I've never seen the point. Is it just to make it easier to call the methods because you don't need to create an object instance to call them? Sorry for the extra questions, the first one is what I'm really wondering about. Not sure how to describe what I'm trying to do here in the title, but here goes with what I am trying to accomplish. I've got a few hundred lines of code in total so far, so I'll try to keep it as short as I can. I've got an application that I am programming using classes for each module and right now I am coding the base classes that I need in order for it to run (database, errors, logging, etc). What I'm doing for my database class is I have a query factory and it extends the MySQLi class so I can process, clean and code the rest of my app faster. I also have another, unrelated class "Error", which will be used for processing errors I might come across. I'd rather do it this way instead of having to call trigger_error and error_log every time there is an error. I'd also not like to have to call a new instance of an object every time I need to use something from that class. Is there any way I can call a class within a class and return it as an object for all the methods within the class? I've tried the methods below, but no luck I've tried others, but I'm trying to keep it brief and get what I'm trying to do across. <?php class QueryFactory extends MySQLi { public $err = new error(); //Doesn't work. public $err = error(); //Nope. #This is the function that I need the $err object for. function set($fields, $newvals) { if ( is_array($fields) && is_array($newvals) ) { if ( count($fields) != count($newvals) ) { //Instead of below, I want to do something like $err->('Array lengths must match for method', 256, $islogged = 1); trigger_error('Array lengths must match for method', 256); } } } } The thing is, I have a "run.inc.php" which does include and create new objects for running just the basic app and if I try to redeclare the error class in query.class.php, it gives me an error saying I can't do that, but if i try to call $err from the page that has all the classes defined it throws an error saying that my method is undeclared. I'd like my error class be available to every other class I create so I can display and log errors as needed. Any suggestions or links to point me where I'd like to go? Hi, how i could do this with gdlibrary: I make image with imagecreatefrompng , and that is my pictures background. Then I add image there, and that is my bird flying in the background. that is only example, i wanna just add image to image What do I need to do in order to use the libssh2 library? Hi, I would like my users to create and save forms via mysql. They should be able to choose what field they want to use, and other users should be able to fill the forms into mysql. Any ideas on how to accomplish this? Hi everyone. There are two nice script which are advanced for me to understand. There is a Knockout tournament scheduler class that makes image of the bracket. and there is a code that makes html of the bracket with jquery. I want to use the class with jquery. but I don't know how to do that and where to start. the class below needs to implement to this http://whileonefork.blogspot.com/2010/10/jquery-json-to-draw-elimination-single.html I attached the php script. please help me! Code: [Select] <?php class KnockoutGD extends Knockout { private $im = null; // GD-lib image resource. private $tc = 0; // Text color. public function getImage($tourName = '') { /* Returns a GD-lib image resource */ // Initial testing. if (empty($this->roundsInfo)) return null; // Dimensional parameters. $fh = imagefontheight(FONT); $fw = imagefontwidth(FONT); $lpad = 30; // Line (branch) padding before and after competitor names and after scores. $hpad = 20; // Outer horizontal image padding. $vpad = 60; // Outer vertical image padding. $lw = $this->getStrLen()*$fw + 3*$lpad; // Line (branch) width.

Like above, if a play-in round exists the x-size of the image must be changed. In this case, we merely add the length of a branch to the total x-size, since all branches are equal in length. Besides that, we add another whole branch length for the Winner/Champion branch, which technically is not a part of the tournament bracket, but is shown anyway. */ $x = 2*$horizPad + (log($frGames*2, 2) + ($playInExists ? 1 : 0) + 1) * $lineWidth; return array('x' => $x, 'y' => $y); } private function getStrLen() { /* Returns the length of longest string used in either rounds.

So I did and now I get the message: Unable to Load Dynamic Library in a pop-up window. I'm lost and don't know how to solve this I'm trying to write a script that will copy images from one website (a supplier, in this case puma) and save them to the dealer's web server. I have already done this for other supplier's websites but puma uses png's instead of jpeg's and I believe that is what is causing my issues: The original image looks like this: The copied image some odd colors in the background like this: Here is the code: Code: [Select] $puma_image = "http://www.pumab2b.com/_static/images/styleColors/1234560002/" . str_replace(" ", "", $Item_Num) . "_1.png"; $image = imagecreatefrompng($puma_image); if ($image) { //Save image to Soccer Etc server (images folder): if (imagepng($image, "prod_images/" . $cur_Item['Item_Num'] . ".png", 0)) { //DO some other stuff here } } I just noticed after posting the original image on this forum, that it is actually transparent. I'm guessing this has something to do with my problems? Hey guys, I have created combined images from edits I had laying around. I have a chair, and i'm trying to combine different colored tops with a pair of legs using a radio button to choose the top color. Here is what I have so far for the form page: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Untitled Document</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <label>Seat Color Choices:</label><br> Red<input type="radio" name="color" value="red" id="red" onFocus="getElementById('config').src = 'red.php'" > Orange<input type="radio" name="color" value="orange" id="orange" onFocus="getElementById('config').src = 'orange.php'" > Ivory<input type="radio" name="color" value="ivory" id="ivory" onFocus="getElementById('config').src = 'ivory.php'" > Black<input type="radio" name="color" value="black" id="black" onFocus="getElementById('config').src = 'black.php'" > </form> <img src="black.php" id="config" alt="color choice for lola chair"> </body> </html> ...and here is one of my image files for an example: <?php //Report any errors ini_set ("display_errors", "1"); error_reporting(E_ALL); //Set the correct content type header('content-type: image/jpeg'); $base = imagecreatefromjpeg('lola_base.jpg'); $red = imagecreatefromgif('lola_red.gif'); $orange = imagecreatefromgif('lola_orange.gif'); $ivory = imagecreatefromgif('lola_ivory.gif'); $black = imagecreatefromgif('lola_black.gif'); imagecopy($base, $red, 0 , 0 , 0, 0,250, 250); imagejpeg($base); //Clear up memory used imagedestroy($base); ?> The problem is, I need to be able to dynamically change which images are being combined. I can't have a different file for each combo (ex. red.gif, black.gif, ivory.gif, etc.) I need it to create them on cue from a single file/function. Is there a way to do that with PHP GD library? hi, i'm using the fpdf library to generate PDF's from form input. It all worked well on my local host, but now that i have transferred to a web server it displays the following error when trying to generate a PDF. Warning: require(/fpdf16/fpdf.php) [function.require]: failed to open stream: No such file or directory in /home/ddgq0o2n/public_html/quote_builder/pdf.php on line 2 Fatal error: require() [function.require]: Failed opening required '/fpdf16/fpdf.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/ddgq0o2n/public_html/quote_builder/pdf.php on line 2 i have searched for "include_path", but can't find it anywhere. i'm thinking it's a server problem, where the library may not be compatible or something needs to be switched on, as it worked fine on my local host. any help and suggestions welcome thanks. I am trying to create a basic image with GD library, but my browser says that the image cannot be displayed because it contains errors... I have no idea why. Here's my code: Code: [Select] switch($_GET['case']){ case "progressbar": header('Content-Type: image/jpeg'); $barWidth = 6; $barHeight = 14; $barPadding = 2; $imageWidth = ($barWidth * 10) + (10 * $barPadding); $imageHeight = ($barHeight + ($barPadding * 2)); $img = @imagecreate($imageWidth, $imageHeight); $imgBorder = imagecolorallocate($img, 0, 0, 0); //imagefilledrectangle($img, 1, $imageHeight -1, $imageWidth - 1, $imageHeight - 1, $imgBorder); $output = "Hello, world!"; imagestring($img, 1, 4, 4, $output, $imgBorder); imagejpeg($img); imagedestroy($img); break; } I have a file called image.php that i use to create images and I use the URL image.php?case=progressbar. Thats my question. Its a good practice? Gives error in a php file without html, for example? About the library, i have a 1500lines single php file and i modualritizing it. There is any advice in general when creating a php library? Hey Guys Ok I can postion text using the GD library using the following: Code: [Select] imagefttext($rImg, 13, 0, 105, 55, $black, $font_file,$Username); How would do the same using an image? For example Code: [Select] whateverfunction($rImg, 13, 0, 105, 55,$ImagePath); Thanks a million.
How to implement the library
here's my code
<?php
include("../incs/config.php");
$result = mysqli_query($link, "SELECT * FROM press ORDER BY press_date DESC");
$result2 = mysqli_query($link, "SELECT * FROM event ORDER BY event_date DESC");
$result3 = mysqli_query($link, "SELECT * FROM galleries ORDER BY gallery_id DESC");
if (!isset($_COOKIE['user'])) {
die("Identifiant invalide");
}

Edited October 16, 2019 by samplephp GD Library Pattern Background ? Hi all I have a simple page here that uses the GD Library to display text in a selected font and size etc. http://www.ttmt.org.uk/forum/ At moment the stripped background goes from the code. Is there a way to have an image as the background instead of the stripped background.

Can this be done simply with a database connection or will the images need to be uploaded to a server? Bit confused as to how it works and which is the best way to go about it. Thanks for any help. Edited January 12 by Richie1209Font size GD Library Hi All I'm trying to create a font tester - http://www.ttmt.org.uk/fonts/index.php (this demo doesn't use the font I'm using.). I'm using the GD library to create images of the text. I'm not happy with the quality of the fonts at small sizes. I've tried everything to fix it but nothing is working. One suggestion I had was to create the fonts larger then reduce the size of the image. Can anyone offer any advise how I might do this? Code: [Select] <?php header('Content-Type: image/png'); $im = imagecreatetruecolor(1000, 200); $gray = imagecolorallocate($im, 240, 240, 240); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, 1000, 199, $gray); $text = $_GET['text']; $textSize = $_GET['size']; $font = $_GET['font']; imagefttext($im, $textSize, 0, 15, 160, $black, $font, $text); imagepng($im); imagedestroy($im); ?> Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>untitled</title> <style type="text/css"> *{margin:0;padding:0;} #wrap{margin:20px 0 0 20px;} h1{margin:0px 0 20px 0;clear:both;} h2{font-size:1.1em;margin:15px 0 5px 0;} #top{padding:0 0 20px 0;} form{margin:0 0 20px 0;} </style> </head> <body> <div id="wrap"> <form action="index.php" method="post"> <!--<input type="text" name="text" value="<?php echo $_POST['text'];?>" />--> <select name="text" > <option value="<?php echo $_POST['text'];?>">Text</option> <option value="ABCDEFGHIJKLMNOPQRSTUVWXYZ">ABCDEFGHIJKLMNOPQRSTUVWXYZ</option> <option value="abcdefghijklmnopqrstuvwxyz">abcdefghijklmnopqrstuvwxyz</option> <option value="0123456789">0123456789</option> </select> <select name="size"> <option value="<?php echo $_POST['size'];?>">Size</option> <option value="10">10</option> <option value="12">12</option> <option value="14">14</option> <option value="18">18</option> <option value="24">24</option> <option value="30">30</option> <option value="38">38</option> <option value="42">42</option> <option value="50">50</option> <option value="60">60</option> <option value="80">80</option> <option value="100">100</option> </select> <input type="submit" name="submit" value="Set →" /> </form> <div id="top"> <?php $theFont="corbelb.ttf"; if(!empty($_POST['submit'])){ $myText = $_POST['text']; $mySize = $_POST['size']; echo '<img src="imageftt.php?text='.$myText.'&size='.$mySize.'&font='.$theFont.'">'; }else{ $myText = "Handgloves"; $mySize = 24; echo '<img src="imageftt.php?text='.$myText.'&size='.$mySize.'&font='.$theFont.'">'; } ?> </div> </div> </body> </html> Hello everyone, What is the best way to take HTML formatted text and overlay it on a image (presumably using php's GD functions)? Unfortunately, HTML tags are ignored and any kind of code is treated as plaintext by imagefttext(). However, I need this HTML DIV box pasted onto an image and I intend to get it done. To make things slightly worst, this is a dynamic, PHP generated DIV box. I had an idea of utilizing some kind of buffering to generate my DIV box, convert that DIV box to an image and finally paste it onto my image using the GD library. If that sounds like a reasonable idea, can someone please help me get started? Thanks in advance, guys! Hello, what's the correct use of GD library to compress JPG images please? I am using this upload script with TinyMCE. See below : I have this snippet but it doesn't compress the image:
// Accept upload if there was no origin, or if it is an accepted origin
// If image is JPEG compress with GD library
$filetowrite = $imageFolder . $temp['name'];
if (in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("jpg", "jpeg"))) {
imagejpeg($temp['tmp_name'], $filetowrite, 75);
} else {
move_uploaded_file($temp['tmp_name'], $filetowrite);
}
<?php
$accepted_origins = array("http://localhost", "http://127.0.0.1", "http://192.168.1.1", "http://example.com");
$month = strtolower(date('M'));
$year = date('Y');
$newspath = "img/news/";
if (!is_dir("$newspath/$year/$month")) {
mkdir("$newspath/$year/$month", 0777, true);
}
$imageFolder = "$newspath/$year/$month/";
reset ($_FILES);
$temp = current($_FILES);
if (is_uploaded_file($temp['tmp_name'])){
if (isset($_SERVER['HTTP_ORIGIN'])) {
// same-origin requests won't set an origin. If the origin is set, it must be valid.
if (in_array($_SERVER['HTTP_ORIGIN'], $accepted_origins)) {
header('Access-Control-Allow-Origin: ' . $_SERVER['HTTP_ORIGIN']);
} else {
header("HTTP/1.1 403 Origin Denied");
return;
}
}
/*
If your script needs to receive cookies, set images_upload_credentials : true in
the configuration and enable the following two headers.
*/
// header('Access-Control-Allow-Credentials: true');
// header('P3P: CP="There is no P3P policy."');
// Sanitize input
if (preg_match("/([^\w\s\d\-_~,;:\[\]\(\).])|([\.]{2,})/", $temp['name'])) {

Hi, I need to unlink my images in my Media Library (wordpress) on my blog: http://www.jbiddulph.com/blog/index.php/featured/ Please help?! I think it is in this piece of code: foreach ( $attachments as $id => $attachment ) { $link = isset($attr['link']) && 'file' == $attr['link'] ? wp_get_attachment_link($id, $size, false, false) : wp_get_attachment_link($id, $size, true, false); $output .= "$link"; if ( $captiontag && trim($attachment->post_excerpt) ) { $output .= " " . wptexturize($attachment->post_excerpt) . " "; } if ( $columns > 0 && ++$i % $columns == 0 ) $output .= ''; } |
