PHP - Php Shape/ Pattern Recognition Inside Image

Is there any way to do this? My image is not appearing below. The text, "we are sorry..." is appearing...

Code: [Select]
if(!isset($_POST['comments'])) {
 
        died('<img src="images/head/head_error.gif"/><br>We are sorry, but there appears to be a problem with the form you submitted.');
}

Hi,

I'm new to PHP so sorry if it is difficult to understand my question. I've just added a new custom field for my website home page (home.php). I've image link inside that custom field and now I want to display that image at Home (Home.php ).

Please let me know what code/loop should I add in home.php to get that image display with size of 100*50 px .

I hope you understand what I meant to.

Thank You.

So I was stumbling around with Repositories and Interfaces and got a decent grasp on it. However, I started running into abstraction and started to implement a little bit of the Factory design.   How often is this typically used? It seems like I should be using  Factory with 90% of my Repositories since there are different types of Items, Tutorials, Random Events, etc.   Items - Food - Weapon - Toy   Tutorials - Newbie - Farming   Random Events - Coin Giving - Item Giving - Item Draining   Things like this... so all of them have similar methods involved. So they each have a base method, for example.. an Item child class would always have the use() method and a factory would determine which kind of object to initiate from your controller just from the item model being passed through. So therefore you can call use() on the repository instance it returns. Then I was moving onto my tutorials and random events and it just seemed very similar.   So in most cases, will factories be a huge plus? Just wanted some general opinions from the PHP developers =) Thanks!

How to make "hints" as dynamic varaible:

Hey Guys. I am learning about the Enterprise pattern, and to me it seems like its the same as the MVC pattern (which I learned about) Do they work the same??   For those who know Martin Fowler's Patterns of Enterprise Application Structure, that is what I am referring to as the enterprise pattern

(example I looked at: http://develturk.com/tags/selfinstance/)

I've looked into the singleton pattern and a few examples. I've understood most of its concept, but I still have a few things puzzling me. I noticed that you're not supposed to allow cloning (obviously) or the construction method as it shows in an example:


    //this object can not copy
    //except the getInstance() method.
    private function __clone() {}
   
    //prevent directly access
    //we want acces this only from getInstance method.
    private function __construct(){}


Do I also have to do this for child classes, or just the parent class?

I have a questions regarding Singleton Pattern in this video: http://www.youtube.com/watch?v=-uLbG7nJCJw&feature=plcp&context=C49f92beVDvjVQa1PpcFMxdGEHDoxYON2LEGpH0krK5UV1HfoVHGM=

Using the singleton pattern, isn't possible to have methods that aren't static? In this video it shows nothing but static methods. Also, after creating the class object like so:

$database = Database:Connect();

How would I go about using normal functions with that object? Say I had a query function. I can't do this:

$database->query();

So what would I do? :/ - Thanks for any help regarding this.

I'm trying to preg_match $text for specific words, defined in an array.

$text = "PHP is a programming language of choice";
 

$text = "This is a function written in a programming language called PHP.";

$words = array("/java/", "/PHP/", "/html/");

for ($i = 0; $i < count($words); $i++)
{
   preg_match($words[$i], $text, $matches);
}
 

The problem with tis is that it returns 3 arrays, of which only the second one is a match, and the other 2 arrays are empty.
The result is that I get notice error on my echo page because the 1st and 3rd arrays are empty.

if I want the text to be searched for the first matching result, whether it is java, PHP or html, then stop (if possible) and echo/return the result, how will I do that? Perhaps preg_match is not to be used here but instead something like substr?

In the below example, we match 0 or more alphanumeric characters in the beginning and 0 or more alphanumeric characters in the end. Then we create 4 groups. Each group has "?=" which means "the next text must be like this". Now in first group we match any character 8 or more times. The next group we match 0 or more characters and a digit. In the next group we match 0 or more characters and a lowercase letter. In the next group we match 0 or more characters and an uppercase letter.

<?php
$password = "Fyfjk34sdfjfsjq7";

if (preg_match("/^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).*$/", $password)) {
    echo "Your passwords is strong.";
} else {
    echo "Your password is weak.";
}
?>

My question is do these four groups impact each other? That is, the fact that the first group has 8 or more characters means that all the groups must have 8 or more characters. The fact that the second group has a digit means that all the groups must have a digit. Or do they work exclusively meaning that a 4 character word with a single digit would match this pattern, even though first group says it must have 8 characters.

Hello,   I have a file to display

$file_content = file_get_contents("test.php");

This file is encoded.... In this file there is a specific tag call change_me

<change_me> 
&quot;&lt;code&gt; &lt;strong&gt;Example Element&lt;/strong&gt; &lt;/code&gt;&quot;
 </change_me>

I want to use htmlspecialchars_decode function for <change_me> tag only... <change_me> tag is used two times in file.     Thanks

Hi all

I have this simple gd code to produce a filled rectangle with a solid color.

Code: [Select]
<?php
        
header('Content-Type: image/png');

$im = imagecreatetruecolor(1000, 200);

$gray = imagecolorallocate($im, 240, 240, 240);
imagefilledrectangle($im, 0, 0, 1000, 199, $gray);
    

imagepng($im);

imagedestroy($im);

?>

Is it possible to create a rectangle with a pattern such as a lined background.

Hello   I hear alot of talk about reusing a database connection and attempts to solve this.   I came across this post on stackoverflow but am having difficulty understanding as to how this is any different than just creating a instance in a single file and including it via include, require or autoload wherever a db instance is needed.   The pattern talked about in the post is the factory pattern, it seems that the factory is responsible for creating the instance, something which I thought autoloading did without this additional code?   Another thing I am still confused by with all the reuse talk - If 2 seperate users request 2 different pages on our server(2nd user 0.1 second behind the other user) which both refer back to the same db file/factory, are 2 instances created? or is the previuos users instance somehow used aslong as there request has not finished? I thought that the server would make new fresh requests/variables/instantiation etc all over again for every user, perhaps I am wrong.   Thanks in advance.

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.

PHP code

Code: [Select]
<?php
        
header('Content-Type: image/png');

$im = imagecreatetruecolor(900, 215);

$w = imagecolorallocate($im, 255, 255, 255);
$c = imagecolorallocate($im, 220, 220, 220);
$black = imagecolorallocatealpha($im, 0, 0, 0, 20);
$style = array($w,$w,$w,$c,$c,$c);
ImageSetStyle($im, $style);

ImageLine($image, 100, 0, 50, 50, IMG_COLOR_STYLED);
imagefilledrectangle($im, 0, 0, 900, 214, IMG_COLOR_STYLED);
    
  $text = $_GET['text'];
$textSize = $_GET['size'];
$font = $_GET['font'];
  
  imagefttext($im, $textSize, 0, 15, 165, $black, $font, $text);

imagepng($im);

imagedestroy($im);

?>

For example:
 

$text = preg_replace_callback( "/([@][a-zA-Z-0-9]+)/"    , "umentions", $text, 1); 

That 1 parameter means the maximum times it will iterate right? So If I'm doing:

@Nexus

@Cupcake

@George

it will return:




My problem is. I only want it to iterate over the last match in my function:
 

function umentions($matches){
vdump($matches);
    return "(here you would replace: ".$matches[0]." with something)";
}

How is it possible to use limit, and only iterate the last match not the first?
