The PhP scripting runs on the server, so if your domain is directing users to your PC, and your PC is off, then even if you have a PhP redirect page they wouldn't get redirected because your PC is off

What might be possible is to have a PhP redirect script on your free hosting and have your domain pointed at that, and if your PC is on users get redirected to your PC, so in pseudo code terms:

<?php
if(hosting1 = available) {
 header('Location: hosting1/index.php');
}
else {
 echo 'content';
}
?>

Not sure what the argument for the if statement would actually be though, one of the pro's here will need to supply that.

[EDIT]

Also, you'll need to make sure that your free hosting supports PhP if this is to work. I've never used PhP on free hosting before, so I couldn't offer the names of any suitable providers I'm afraid.

[Readie]

I've actually thought of a way to do this without over complicating things.

If you have a file on your main hosting called something like redirect.php, with the following content:

<?php
header('Location: hosting1/index.php');
?>

and then on your free hosting, you have index.php with the following code:

<?php
include 'http://hosting1/redirect.php';
echo 'content';
?>

Then if your server is up, there will be a file for it to pull, which will automatically redirect users to your server; and if it is down, then there will be no redirect for it to run.

Readie: Thank you so much =) i was trying to find this solution since one week but every buddy was talking about DNS & other stupid solution i tested this script u gave me its working but the problem is its taking 10-15 seconds to load but thank you so much =)

[greeny]

Can we print "Please Wait Page is Loading" on page while it load the page ?

[Readie]

I'm fairly certain the

header('Location: ...');

needs to be the very first line in the document to work, and so it would be the first thing to be run.

Nothing else would happen until the server had pulled the redirect.php or verified that it was unavailable; so a echo/print command would happen too late.

The first example I submitted might work more smoothly, but as I said, I'm not sure what the argument for the if statement might be. It might work as:

<?php 
if(http://hosting1/index.php) { 
header('Location: http://example.com/index.php'); 
} 
else { 
echo 'content'; 
} 
?>

But you would probably run into the same problem with load times without an argument that brings a little more finesse.

Just a heads up, the mods don't like us using specific URLs unless they are to authorities (such as php.net)

I am thinking something along the lines of:

<?php
echo '<p>Please wait, page is loading</p>';
$page = 'http://hosting1/index.php';
if(file_exists($page)) {
 echo '<meta http-equiv="refresh" content="0;url=http://hosting1/index.php">;
} else {
 echo '<meta http-equiv="refresh" content="0;url=http://hosting2/serverdown.php">';
}
?>

Unfortunatley, my own testing (using just a plain text echo, rather than a meta to stop annoying local cache problems) is always echoing the "else" - and I'm not sure why, if one of the gurus could take a look, that'd be appreciated.

[greeny]

Sir I tried it Edit it like this please check wotz the error cuz its giving this error

Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home/vhosts/greeny.example.com/index2.php on line 16

====================================================

<?php
echo '<p>Please wait, page is loading</p>';
$page = 'http://greeny.example.com/wordpress';
if(file_exists($page)) {
echo '<meta http-equiv="refresh" content="0;url=http://greeny.example.com/wordpress">;
} else {
echo '<meta http-equiv="refresh" content="0;url=http://greeny.example.com/serverdown.php">';
}
?>

===========================================

PLEASE CHECK why its giving this error? =(

[SuperDuck]

Why don't you ping the server ?

Make an if else statement and you are done!
Sorry if I misunderstood your demands!
change yourip with the ip of the server! don't use " or '
<?php
$str = exec("ping -n 1 -w 1 yourip",$input, $result);
if ($result == 0){
echo "ON";
}else{
echo "OFF";
}
?>

[greeny]

Super Duck can u fix this plz

<?php
echo '<p>Please wait, page is loading</p>';
$page = 'http://greeny.example.com/wordpress';
if(file_exists($page)) {
echo '<meta http-equiv="refresh" content="0;url=http://greeny.example.com/wordpress">;
} else {
echo '<meta http-equiv="refresh" content="0;url=http://greeny.example.com/serverdown.php">';
}
?>

And put ur ping ip codes in this

<?php
$str = exec("ping -n 1 -w 1 yourip",$input, $result);
if ($result == 0){
echo "ON";
}else{
echo "OFF";
}
?>

==========================================
my Auto ip DNS is: greeny.is-a-geek.net
my free hosting URL is: greeny.freetzi.com

thanks

[Readie]

you are missing an apostrophee (') at the end of the first meta tag on the if statement. That will account for the reason you are getting "Unexpected T_STRING"

And so am I on my example, but I was in a bit of a rush when I posted that I'm afraid. My apologies for the confusion.

Readie

Readie: please you complete fIX & past it here plz ill be thankful i m getting confuse =S i m sorry =(

<?php

if ($result == 0){
// here you put the code if the server is up and running! Like header(Location:)
}else{
// here you put the code if the server is down, and you show the 'content' from where the file is hosted (i think greeny.example.com )
}

// still have questions ?, don't hesitate to asq!

[greeny]

I stopped HOST 1 [greeny.example.net...]

i want you guys to test it

[edited by: eelixduppy at 5:33 am (utc) on Dec. 23, 2009]

[Readie]

So far as I can tell, it's working fine.

If you have issues with this though, there is another method (returning to my second idea I posted)

====
HOST 1 redirect.php
====

<?php
echo '<meta http-equiv="refresh" content="0,url=http://hosting1/index.php">';
?>

====
HOST 2 index.php
====

<?php
echo '<meta http-equiv="refresh" content="60,url=http://hosting2/serverdown.php">
<p align="center">Pleas wait, page is loading</p>';
include 'http://hosting1/index.php';
?>

Which will wait 60 seconds before giving up and sending you to your "server is down" page.

I advise only using this method if you experience problems with the method outlined by SuperDuck.

Regards,

Readie

[Readie]

include 'http://hosting1/redirect.php';

Typo fix :/

[SuperDuck]

i still wait to see what have you choosed , both methods are okay from my point of view, so you just have to test them well before choose one!

[greeny]

Readie YOUR CODE WORKED MAN! YOU ROCK ! LOVE YOU ! THANK YOU SO MUCH =) =)

[greeny]

but the problem is its Compitable only with FIREFOX Browser ... when i test it with FirefOX it works but when i test it in IE it doesnt work its keep refreshing the page lOl =D

[greeny]

i m talking about this code =)

====
HOST 1 redirect.php
====

<?php
echo '<meta http-equiv="refresh" content="0,url=http://hosting1/index.php">';
?>

====
HOST 2 index.php
====
<?php
echo '<meta http-equiv="refresh" content="60,url=http://hosting2/serverdown.php">
<p align="center">Pleas wait, page is loading</p>';
include 'http://hosting1/index.php';
?>

[SuperDuck]

than, why don't you try my code? As I said, test well before choose something, use different browsers with different versions, or ask your friends to test! It is one of the most important step when developing something!

[Readie]

I made a mistake Greeny; change

include 'http://hosting1/index.php';

to

include 'http://hosting1/redirect.php';

... As I said to above.

Readie
