Integrating PHP and HTML
8
PHP & HTML PHP and HTML interact a lot: PHP can generate HTML, and HTML can pass information to PHP <head></head> <body class="page_bg"> Hello, today is <?php echo date('l, F jS, Y'); ?>. </body> </html>
9
PHP & HTML <html> <head></head> <body> <ul> <?php for($i=1;$i<=5;$i++){ ?> <li>Menu Item <?php echo $i; ?></li> <?php } ?> </ul> </body> </html> Menu Item 1 Menu Item 2 Menu Item 3 Menu Item 4 Menu Item 5
10
PHP & HTML Use echo to display HTML tags
<?php echo "<html>"; echo "<head></head>"; echo "<body class=\"page_bg\">"; echo "Hello, today is "; echo date('l, F jS, Y'); //other php code here echo "</body>"; echo "</html>"; ?>
11
Passing value from HTML to PHP using Forms
Use $_GET or $_POST <?php $Fname = $_POST["Fname"]; $Lname = $_POST["Lname"]; ?> <html> <head> <title>Personal INFO</title> </head> <body> <form method="post" action="<?php echo $PHP_SELF;?>">#action refers to the php file First Name:<input type="text" name="Fname"><br /> Last Name:<input type="text" name="Lname"><br /> <input type=‘submit’ value=‘Submit’ /> </form> <? echo "Hello, ".$Fname." ".$Lname.".<br />"; ?>

<?php $arr = array(2,4,3,5,1); $sorted = false; while (false === $sorted) { $sorted = true; for ($i = 0; $i < count($arr)-1; ++$i) { $current = $arr[$i]; $next = $arr[$i+1]; if ($next > $current) { $arr[$i] = $next; $arr[$i+1] = $current; } print_r($arr); ?>
