Create a random password using rand() function with length 7 characters

function createRandomPassword() {

$chars = “abcdefghijkmnopqrstuvwxyz023456789!@#$%^&*”;
srand((double)microtime()*1000000);
$i = 0;
$pass = ” ;
while ($i <= 7) {
$num = rand() % 33;
$tmp = substr($chars, $num, 1);
$pass = $pass . $tmp;
$i++;
}

return $pass;
}
// Usage
$password = createRandomPassword();
echo “Your random password is: $password”;

System program execution

Introduction
Those functions provide means to execute commands on the system itself, and means to secure such commands.
Note:
All execution functions call the commands through cmd.exe under Windows. Therefore the user calling these functions needs appropriate privilege to run this command. The only exception is proc_open() with bypass_shell option.

Program execution Functions

See Also

These functions are also closely related to the backtick operator. Also, while in safe mode you must consider the safe_mode_exec_dir directive.
Table of Contents

* escapeshellarg — Escape a string to be used as a shell argument
* escapeshellcmd — Escape shell metacharacters
* exec — Execute an external program
* passthru — Execute an external program and display raw output
* proc_close — Close a process opened by proc_open and return the exit code of that process
* proc_get_status — Get information about a process opened by proc_open
* proc_nice — Change the priority of the current process
* proc_open — Execute a command and open file pointers for input/output
* proc_terminate — Kills a process opened by proc_open
* shell_exec — Execute command via shell and return the complete output as a string
* system — Execute an external program and display the output

Within Linux, when calling the php interpreter directly from popen, or other program execution function to execute a script, it appears as though the script perpetually fails and re-executes.

i.e.

As each re-execution causes the executing script to load under a new PID, it is incredibly difficult to identify and kill the process manually.

[One solution is] to ensure the executing script has a valid shebang, and execute permissions. This allows you to execute the script directly

Get Image Size
1) array getimagesize ( string $filename [, array &$imageinfo ] )
The getimagesize() function will determine the size of any given image file and return the dimensions along with the file type and a height/width text string to be used inside a normal HTML tag and the correspondant HTTP content type.

getimagesize() can also return some more information in imageinfo parameter.

$size = getimagesize(“http://www.example.com/gifs/logo.gif”);

2) int imagesx ( resource $image )
Returns the width of the given image resource.
$img = imagecreatetruecolor(300, 200);

echo imagesx($img); // 300

3) int imagesy ( resource $image )
Returns the height of the given image resource.
$img = imagecreatetruecolor(300, 200);

echo imagesy($img); // 200

1) Find Image size Using getimagesize()
$size = getimagesize(“http://www.example.com/gifs/logo.gif”);
2) If Image Size is grater then required size then put required image size.
3) Also you can set no_image image if no image exist.
$path_parts = “”;
$path_parts = getimagesize(DIR_WS_IMAGES . $best_sellers['products_image']);
$height = “”;
$weight = “”;
if($path_parts[0] > ’140′){
//$height =55;
$weight = 140;
}
$listingProducts_image = “”;
if($best_sellers['products_image']==”" || $best_sellers['products_image']==”NULL”){
$listingProducts_image = “No_Image_Available.gif”;
}else{
$listingProducts_image = $best_sellers['products_image'];
}
