Tools to help you convert from ASP to PHP To keep values in form: E-mail: <input type="text" name="email" value="<?php echo $email;?>"> To capture a form post: if (isset($_POST["Action"])) { $action = $_POST["Action"]; } If statements: <?php if ($gender=="male") echo "checked";?> If statements based on value in recordset against database: if($rs->Fields['useflattheme'] == "1") { $useflattheme="Yes"; } else { $useflattheme="No"; } If then statements: if ($t < "20") { echo "Have a good day!"; } else { echo "Have a good night!"; } Instead of using response.write, use echo: echo $name; To comment: /* your commment */ To concatenate text fields, use a . instead of & : $txt = "W3Schools.com"; echo "I love " . $txt . "!"; To use include files: <?php include 'footer.php';?> To redirect to another page: header('Location: http://www.icbconsulting.com'); or header('Location: login.asp'); To use sessions: <?php session_start( ); ?> <html> <head> <title>Using a session variable</title> </head> <body> <?php echo "my session id ".session_id(); echo "<br>"; $_SESSION['username']="Devin"; echo " and the session has been registered for: ".$_SESSION['username']; ?> </body> </html> To delete a session: session_destroy(); CONDITIONAL HTML: <?php if (condition): ?> html code to run if condition is true <?php else: ?> html code to run if condition is false <?php endif; ?> LInebreaks: "\r\n" is equivalent to vbcrlfDate formatting: // Assuming today is March 10th, 2001, 5:16:18 pm, and that we are in the // Mountain Standard Time (MST) Time Zone NOTE: you need to set time zone: date_default_timezone_set('America/Denver'); NOTE: $today=date("Y-m-d H:i:s"); works with mysql datetime field $today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm $today = date("m.d.y"); // 03.10.01 $today = date("j, n, Y"); // 10, 3, 2001 $today = date("Ymd"); // 20010310 $today = date('h-i-s, j-m-y, it is w Day'); // 05-16-18, 10-03-01, 1631 1618 6 Satpm01 $today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // it is the 10th day. $today = date("D M j G:i:s T Y"); // Sat Mar 10 17:16:18 MST 2001 $today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:18 m is month $today = date("H:i:s"); // 17:16:18 $today = date("Y-m-d H:i:s"); // 2001-03-10 17:16:18 (the MySQL DATETIME format) Incrementing variables: Instead of " variable=variable+1" use ++$variable Searching a string: If (strpos($output,$mysearch)>0) { echo "this worked"; $recaptchagood="Yes"; } |
