Lower Case an Array

Lower Case an Array

Here is an example of how to force all values in array tolower case. This could, of course, be used in the same way to make the array UPPERCASE or do anything else you wish to the array values. Note the that the string is passed to the array by reference. This is so the actual array values are manipulated.

<?php

/*** an array of mixed case words ***/
$array = array('MAC', 'Apple', 'osX');

/**
*
* @Lower case an array
*
* @param ref string $string
*
* @return string
*
*/
function lower(&$string){
$string = strtolower($string);
}

/*** apply the lower function to the array ***/
array_walk($array,'lower');

foreach($array as $value){
echo $value;
}
?>

PHP SCRIPT-- TO TIME OUT THE SESSION AFTER THE PARTICULAR TIME [SESSION TIME OUT]

<?php
if (!isset($_SESSION['timeout_idle'])) {
$_SESSION['timeout_idle'] = time() + MAX_IDLE_TIME; //set time at the first time of writing script
} else {
if ($_SESSION['timeout_idle'] < time()) {
//destroy session if session time is less the what we have set the time
} else {
$_SESSION['timeout_idle'] = time() + MAX_IDLE_TIME; // if continue working on similar site then increase the time of script
}
}
?>

PHP- Remove Special Character during website

// put this code on the top of the page or in your config file. You will never see the special character on that page/website(if you used config on the top then it work on whole website)


header("Content-type: text/html; charset=UTF-8");
ini_set('mbstring.internal_encoding', 'UTF-8');

SEO CONCEPT--GET META TAG IN ARRAY-- SUPPORTED BY PHP

<?php
// Assuming the above tags are at www.example.com
$tags = get_meta_tags('http://www.example.com/');

// Notice how the keys are all lowercase now, and
// how . was replaced by _ in the key.
echo $tags['author']; // name
echo $tags['keywords']; // documentation
echo $tags['description']; // discription
echo $tags['geo_position']; // 49.33;-86.59

var_dump($tags); // get all values

?>

Secure file download from PHP server

< ?php
// local file that should be send to the client
$local_file = 'filename';
// filename that the user gets as default
$download_file = 'if_u_wanna_to_change_file_name_i._e._uploade_then name';
// I u do not want to change name then wrtre
//$download_file = 'if_u_wanna_to_change_file_name_i._e._uploade_then name';


// set the download rate limit (=> 20,5 kb/s)
$download_rate = 20.5;
if(file_exists($local_file) && is_file($local_file)) {
// send headers
header('Cache-control: private');
header('Content-Type: application/octet-stream');
header('Content-Length: '.filesize($local_file));
header('Content-Disposition: filename='.$download_file);

// flush content
flush();
// open file stream
$file = fopen($local_file, "r");
while(!feof($file)) {

// send the current file part to the browser
print fread($file, round($download_rate * 1024));

// flush the content to the browser
flush();

// sleep one second
sleep(1);
}

// close file stream
fclose($file);}
else {
die('Error: The file '.$local_file.' does not exist!');
}
