Basic syntax

I'm running PHP4 and for some reason, I can't get here doc strings to work. Here's what I have

Code:

<?php echo <<<EOT
A sentence
spanning in multiple
lines.
EOT
?>

As far as I'm concerned, I'm following the rules of the language by specifiying the identifiers and the closing identier stands alone in a newline. Any ideas why I'm having parsing errors?

You haven't included a semicolon after EOT, right? That could be the error.

Why are you printing out text with EOT..do like this..

Code:

<?php 

echo "Hello World \n";
echo "Printing another line on a line under \n";
echo "Printing this text on the same line";

?>

If you want to handle chunks of text or arrays use for or while loops for that.

Well, it _is_ easier to write heredocs instead of doing such things.

No its not good programming....

Now that depends on what programming language you're using. In shell scripting, it's most certainly good programming, and I can't say that there's anything wrong with it in PHP either. What do you have against it? In PHP, it's just another way of quoting, and there's not anything wrong with quoting.

Sorry for the late reponse but after checking my code, there is a semi colon after the closing identifer EOT.

**Dolda2000** · 05-26-2003

Are you sure? I just tried the following, and it worked perfectly for me.

Code:

<?php echo <<<EOT
Test
Test
Test
EOT;
?>

Well here's the thing. I installed the php4 package from debian. I double checked to see that this was v4 instead of v3 since this is only supported in v4. I'm using apache to look at this since I don't have the command line interpreter installed on the machine. Looking through the file httpd.conf, everything seems to be in place regarding php4 so I don't know what the problem is. Could it be that there is an option to turn this on during installation and that Debian's package left out this option?

I wouldn't think so, but who knows? Stranger things have happened, after all. Maybe you should try to install it from source instead?
