php if statement help

[bobby2guns2003]

Hey, I would I make a php if statement that would do this:

if $forumid = 11 then redirect to www.example.com

As long as you haven't had any output on that page, try


if ($forumid == 11)
{
header("Location: http://www.example.com");
}

if ($forumid == 11)
{
header("Location: http://www.example.com");
}

The above is your code, should it be this below? (Semi colon at the end of line 1)


if ($forumid == 11);
{
header("Location: http://www.example.com");
}

No, i was pointing it out so that the thread starter does not have bad code on there site which will cause errors.

No, it shouldn't. You don't have a semi-colon with functions that have {} like while, if, else etc. Only what's inside the {}

Putting a semi-colon after the if statement would return a parse error. On some more-lenient servers, it might just terminate the if statement.

And keep in mind you can only use the "header" function to redirect if there has been no HTML output yet.

Hey, I would I make a php if statement that would do this:

if $forumid = 11 then redirect to www.example.com

maybe something like this could work:


<?php
/* predefined list of available url redirects - could also be array from database*/
$urls=array();
$urls[1]="http://www.google.com";
$urls[2]="http://www.freewebspace.net";
$urls[3]="http://www.deluxnetwork.com";

if(isset($id)){
$url=$urls[$id];
if($url==""){
header("Location: http://www.default.com/");
}
else{
header("Location: $urls[$id]");
}
}
?>

{
header("Location: http://www.example.com");
}

{
header("Location: http://www.example.com");

Wow. You know absolutely nothing about PHP syntax, do you?

[R4g1ng]

I don't think that was necessary. One of the most basic rules of PHP is to have a semi-colon at the end of things, with some exceptions. If he just started learning, he might've not known that.

[hostndomain]

if ($forumid == 11)
{
header("Location: http://www.example.com");
}

is OK but if you see some HTML headers ERROR just add this line on start of the page before any code and html.

ob_start();
