Redirect

[zulfer]

Whats the most efficient and simplest way of redirecting a user to another PHP/Htm page through PHP.

For e.g
<?php
If (a==2){
// GOTO help.php

}

?>

[intenz]

Try this...

<?
if($a == 2)
{
header('Location: help.php');
}
?>

I get the following error when I do this

Cannot add header information - headers already sent by (output started at D:\websites\ups\ups\index.php:7) in D:\websites\ups\ups\index.php on line 174

any other better way ?

<?php
//if in this situation, redirect
if (...)
{
?>
<script language=javascript>
history.go(-1) //to make the back button working
document.location.href="whereyouwanttogo.html";//redirect
</script>
<?php
}
?>

and ensure you have no white space above your <?php

not sure if this is any good but removes the issue of header errors that i normally get:

echo("<META HTTP-EQUIV=\"Refresh\" CONTENT=\"0; URL= YOUR URL HERE!!!! \">");

never use parenthesis around echo

"echo() is not actually a function (it is a language construct) so you are not required to use parentheses with it. In fact, if you want to pass more than one parameter to echo, you must not enclose the parameters within parentheses. It is not possible to use echo() in a variable function context, but you can use print() instead."

also if the code you are using doesn't need to be parsed then don't parse it. anything within "" is parsed, so use ' otherwise, with lots of code it will give the server less work and speed things up:

echo '<META HTTP-EQUIV="Refresh" CONTENT="0; URL=YOUR URL HERE!!!!" />';

and if you get errors then that shows poor script design. There are a number of methods of getting round the problem. A class to gather and display information is my prefered method. Other people prefer OB, but whatever you want.

the best method as already given is header('Location: help.php');
