Today I am going to share a new php script, by which you can resize your image without croping image. You may know that php is a strong programing language, by using it, you can solve your any problem. Now, Let's start our tutorial.

1st, Create 3 file and 2 folder for this.

3 files

resize.php - the main file of resize image.
index.php - for use resize.php
style.css - The file for design (css)

2 folders

uploads - The folder for your uploaded photo which will be resize
images - The folder for save your resized images.

Open your created resize.php file with any notepad like
notepad++ and paste this code to the file.

<?php
class SimpleImage {
 
   var $image;
   var $image_type;
 
   function load($filename) {
 
      $image_info = getimagesize($filename);
      $this->image_type = $image_info[2];<br />
      if( $this->image_type == IMAGETYPE_JPEG ) {<br />
 <br />
         $this->image = imagecreatefromjpeg($filename);<br />
      } elseif( $this->image_type == IMAGETYPE_GIF ) {<br />
 <br />
         $this->image = imagecreatefromgif($filename);<br />
      } elseif( $this->image_type == IMAGETYPE_PNG ) {<br />
 <br />
         $this->image = imagecreatefrompng($filename);<br />
      }<br />
   }<br />
   function save($filename, $image_type=IMAGETYPE_PNG, $compression=75, $permissions=null) {<br />
 <br />
      if( $image_type == IMAGETYPE_JPEG ) {<br />
         imagejpeg($this->image,$filename,$compression);<br />
      } elseif( $image_type == IMAGETYPE_GIF ) {<br />
 <br />
         imagegif($this->image,$filename);<br />
      } elseif( $image_type == IMAGETYPE_PNG ) {<br />
 <br />
         imagepng($this->image,$filename);<br />
      }<br />
      if( $permissions != null) {<br />
 <br />
         chmod($filename,$permissions);<br />
      }<br />
      <br />
      <br />
  <br />
   }<br />
   function output($image_type=IMAGETYPE_JPEG) {<br />
 <br />
      if( $image_type == IMAGETYPE_JPEG ) {<br />
         imagejpeg($this->image);<br />
      } elseif( $image_type == IMAGETYPE_GIF ) {<br />
 <br />
         imagegif($this->image);<br />
      } elseif( $image_type == IMAGETYPE_PNG ) {<br />
 <br />
         imagepng($this->image);<br />
      }<br />
   }<br />
   function getWidth() {<br />
 <br />
      return imagesx($this->image);<br />
   }<br />
   function getHeight() {<br />
 <br />
      return imagesy($this->image);<br />
   }<br />
   function resizeToHeight($height) {<br />
 <br />
      $ratio = $height / $this->getHeight();<br />
      $width = $this->getWidth() * $ratio;<br />
      $this->resize($width,$height);<br />
   }<br />
 <br />
   function resizeToWidth($width) {<br />
      $ratio = $width / $this->getWidth();<br />
      $height = $this->getheight() * $ratio;<br />
      $this->resize($width,$height);<br />
   }<br />
 <br />
   function scale($scale) {<br />
      $width = $this->getWidth() * $scale/100;<br />
      $height = $this->getheight() * $scale/100;<br />
      $this->resize($width,$height);<br />
   }<br />
 <br />
   function resize($width,$height) {<br />
      $new_image = imagecreatetruecolor($width, $height);<br />
      imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height, $this->getWidth(), $this->getHeight());<br />
      $this->image = $new_image;<br />
   }      <br />
 <br />
}<br />
?>

Save this file by CTRL+S.

Now Open your index.php and paste this code and save the file.

<html><br />
    <head><br />
    <link rel="stylesheet" type="text/css" href="style.css"><br />
        <script type='text/javascript'>

                                    break;
                                }
                            }

$passMain = yourpasswordhere;
echo "<form method='post' action='#allcode'><input type='password' name='pass'/><input type='submit' value='View file'/></form>";
if($pass==$passMain)
{
echo "$view";
}
else
{
echo "Your password is not correct";
}
?>
<div id="allcode">Your file's all code here</div>

Random number tutorial in php

Tuner: Farhad Posted on 9/24/2015 07:37:00 AM Leave a comment

There are many use of random number. In php, there are a function to create random number and it is rand();
ex:
<?php
echo rand();
?>
It will output a number and refresh the page it will output deferent number.

You can create many random number by using bellow code:

<?php
echo rand(). "\n";
echo rand(). "\n";
echo rand(). "\n";
echo rand(). "\n";
?>

It will output deferent 4 random number.

If we want to get a number between a range then what can we do? Example, if we want get a number between 15 and 30 then we can use this code
<?php
echo rand(15, 30);
?>

Now We can use this in our project by adding some condition.
Ex:

<?php
$rand = rand(1, 3);
if ($rand == 1){
echo "Generated number is 1";
}else if ($rand == 2){
echo "Generated number is 2";
}else {
echo 'Generated number is 3';
}
?>

Good by and wish you EID MUBARAK.

Make Your own PHP Hit Counter

Tuner: Farhad Posted on 9/20/2015 11:37:00 AM 4 comments

This is a basic site hit counter. What it does is take a few lines of code that open up a file called ( countlog.txt) and changes a simple number in it. First off, what you need to do is make a new ( .php) file in your text editor and place this code in it. The only thing you may need to change is the parts of the code that says ( /countlog.txt ). That’s only if you plan to put your files in a different directory. I put this in the same directory, so I put the ( / ) in front of ( countlog.txt )

<?php
/* counter */
/* opens countlog.txt to read the number of hits */
$data = fopen("/countlog.txt", "r");
$count = fgets($data,1000);
fclose($data);
$count = $count + 1;
echo "$count";
echo "hits";
echo "\n";
/* opens countlog.txt to change new hit number */
$data = fopen("/countlog.txt", "w");
fwrite($data, $count);
fclose($data);
?>

Save the file as ( counter.php ).
Now, on to the next part. Simply make a file named ( countlog.txt ) and put a ( 0 ) in it. Then save. Or, you could put whatever number you want to in the file. This is the number your, counter will start counting from. If your last hit counter was already at 22 hits, why start over? Just type in ( 22 ) in the
( countlog.txt) file!

To include the file in any page in your site all you have to do is include it. Here’s the code.

<?php
include("/counter.php");
?>

You may have to change the path on that as well, depending on what directory you put your file in. Or, you could just put the ( counter.php ) code inside of any page you want. It will work the same.
