ECHO does not work in php

**mcolton** · 03-10-2011, 11:04 PM

Edited: I found out that I cannot echo at all. I tried a small program below and when I run it, I get a blank page.

PHP Code:


<html>

<body>

<?php 

echo 'You will be re-directed in 3 seconds';

?>

</body>

</html>

The original problem is below:

I have a piece of code below and when I get to this condition, I want to print "You have already registered" and then return to the page shown in the "header" line

Before the following php code, I have checked mysql and either found 1 or 0 records. If I find 1 record, that is when I want to alert the user he is already registered. Thanks for any help

PHP Code:


if ($num==1) {

  mysql_close();

  echo ' you are already registered' ;

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

}

Are any functions working for you?

Try doing:

PHP Code:


<?php

phpinfo();

?>

That should print out a lot of information about PHP and your setup.

If it doesn't, then there's probably something wrong with how your server is set up.

Also no output can be displayed if you are using a header.

PHP Code:


echo ' you are already registered' ;

header("Location: http://www.lotatennis.com"); // this wont execute with the echo

phpinfo didn't show anything.
I took the "header" line out and still nothing.
I know I'm getting to this test file because I put a line of text in there:

PHP Code:


<html>

<body>

text

<?php 

phpinfo();

?>

</body>

</html>

When I ran this, I got "text" and thats all. If I take the "text" out, I get nothing. I KNOW PHP is working because the whole rest of my code IS working.

Is the file that this code is in a php file? ie - does it end with the .php extension

**mcolton** · 03-11-2011, 08:35 PM

no. it is a html file

**Beverleyh** · 03-11-2011, 09:53 PM

There's your answer

**mcolton** · 03-11-2011, 11:54 PM

I don't understand. That little test file is html. My original code that is not working (below) is in a php file:

PHP Code:


if ($num==1) { 

  mysql_close(); 

  echo ' you are already registered' ; 

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

}

Beverley is saying that PHP will only execute when the extension is .php, and never on an .htm or .html page.

(Technically you could reconfigure your server, but that's not relevant here.)

For EVERY page on which you are trying to run PHP, is the extension .php? That's step 1. Then try the phpinfo() code again.

Bluewalrus mentioned it, but you may have missed it;

this won't work:

the header will fail because you've already sent output (the text) to the browser.
if you switch the order:

PHP Code:


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

echo ' you are already registered' ;

then the echo won't be seen, because the user has already been redirected to the other page.

If you want to do this (show a notice and then redirect), it has to be done on the client side; there's no way to do it from the server. use javascript or a html header.
