ternary operator ?:

ternary operation is not hard but not easy to use.
it can be short form of if...else and switch...case it is used in an expression as follows :
condition ? valueIfTrue : valueIfFalse
therefore we wrote

if($i>5){
 echo 'more than 5';
}else{
 echo 'not more than 5';
}

by ternary operator we can use just only

echo ($i>5)?'more than 5':'not more than 5';

or something like

$action = (empty($_POST['action'])) ? 'default' : $_POST['action'];

instead of

if (empty($_POST['action'])) {
    $action = 'default';
} else {
    $action = $_POST['action'];
}

you can also use ?: instead of switch case too.

php protect file with limit download rate

$local_file = 'file.zip';
$download_file = 'name.zip';
// set the download rate limit (=> 20,5 kb/s)
$download_rate = 20.5;

if(file_exists($local_file) && is_file($local_file)){
    header('Cache-control: private');
    header('Content-Type: application/octet-stream');
    header('Content-Length: '.filesize($local_file));
    header('Content-Disposition: filename='.$download_file);
    flush();
    $file = fopen($local_file, "r");
    while(!feof($file)){
        // send the current file part to the browser
        print fread($file, round($download_rate * 1024));
        // flush the content to the browser
        flush();
        // sleep one second
        sleep(1);
    }
    fclose($file);
}else {
    die('Error: The file '.$local_file.' does not exist!');
}

Your own favorite Fonts on web

If you have your font and want to put in webpage try this method
1) created from existing TrueType font files(.ttf) using Microsoft's Web Embedding Fonts Tool (WEFT). (A similar software product called "FAIRY", by BorWare AG, also generated .eot files, with some improvements.)
2) embeddeb font with the css

@font-face {
  font-family: 05_ZZ Death Note 1.0;
  font-style:  normal;
  font-weight: normal;
  src: url(ZZDEATH1.eot);
}
.deathnote { font-family: "05_ZZ Death Note 1.0"; }

and use the code in html

<FONT FACE="05_ZZ Death Note 1.0" SIZE="5"> Aa Bb Cc Dd Ee Ff Gg </FONT>
or
<div class="deathnote">testing</div>
