The PHP Redirect command

<?php
header("location: [some-url]");
?>

Replace [some-url] with the URL where you want the redirection to take place.

For example,

header("location: ./version2/index.html"); =>redirect to "index.html" page in
subfolder called "version2"
header("location: http://www.yahoo.com"); =>redirect to a website called yahoo.com

If PHP is not available, it's also possible to use other redirects:

HTTP Redirects

<meta http-equiv="Refresh" content="[time];
URL=[some-url]">

Replace [time] with seconds. This will pause the browser for the specified number of seconds. Replace [some-url] with the target URL you want to redirect.

For example,

<meta http-equiv="Refresh" content="5;
URL=http://www.yahoo.com">

The above HTTP based redirect needs to be in the region of the HTML code.

JavaScript Redirects

<script language=javascript>
setTimeout("location.href='[some-url]'",[time]);
</script>

Replace [time] with milliseconds. This will pause the browser for the specified number of seconds. Replace [some-url] with the target URL you want to redirect.

For example,

setTimeout("location.href='http://www.yahoo.com'", 5000);

The above JavaScript based redirect can be either in the or region of the HTML code.
Usually a PHP redirect is much more reliable than other form of redirects like HTTP redirect or JavaScript based redirects. For example a JavaScript redirect may not work if a user's browser settings has JavaScript turned off.

The reason why PHP redirects will work no matter what settings users have on their browser is because PHP is server side script. It will not depend on browser settings that may affect JavaScript which is parsed on the client-side/user-side.

Simple Patterns

• metacharacters :
• .  ^  $  *  +  ?  {  [  ]  \  |  (  )
  

• [abc] = [a-c] : will match any of the characters "a", "b" or "c"
• metacharacters are not active inside classes.
• [abc$] : will match any of the characters of "a", "b", "c" or "$"
• "$" is usually a metacharacter, but inside a character class it's stripped of its special nature.
• not within the range-- complementing
• [^5] : will match any character except "5"
• .
• match anything except a newline character
  
• "\" is used to escape all the metacharactes so you can still match them in patterns
• \[ or \\ : match "[" or "\"
• \d = [0-9]
  
• match any decimal digit
• \D = [^0-9]
• match any non-digit character
• \s = [\t\n\r\f\v]
• match nay whitespace character
• \S = [^\t\n\r\f\v]
• match any non-whitespace character
• \w = [a-zA-Z0-9_]
• match any alphanumeric character
• \W = [^a-zA-Z0-9_]
• match any non-alphanumeric character
•

#Fetch all results from the cursor into a sequence and close the connection
