It's heredoc syntax.

Ok, let's gather some stats to see how many people actually use the
heredoc syntax. I created this quick little form to gather the data.
It's takes 2 seconds (literally) - vote here:
http://thril.uark.edu/heredoc/
I'm interested in knowing if this is used a lot. If it is, then I may
consider tying it into my code (if it calls for it).

I've always had problems with heredoc when I try using arrays like that. I
will either pull them into a straight $foo, or use the ${} thing.

Isn't that form (sans quote marks) deprecated and frowned upon?

Heredoc is truly a great thing. You'll learn to love heredoc whenever you
have tons of stuff you need to print instead of escaping php. A great
example is output that comes from classes, where you can't break the class
into multiple code blocks. Just don't forget that heredoc end part has to be
on the very next line with no whitespace to start. Confusing at times.
Cheers!

I'm interested in knowing if this is used a lot. If it is, then I may

I recommend that you to make your decision about using heredoc based
on whether the syntax itself makes good sense to you, not based on
which number or percentage of other programmers use it.
I love using heredoc and I don't give a rat's ass if there are only
three other people in the world who use it. It absolutely makes
sense to me, helps me write better code with fewer errors and that's
much easier to read. I know from previous discussions of this topic
that it gives some people the freakin' heebee-jeebies. That's fine;
different strokes; doesn't matter. It's just one tool.
I use heredoc mostly for SQL queries, for html blocks, for inline
html assembly, and for other circumstances in which I'm merging
literals & variables. If a statement gets messy with too many
concatenations, I'll use heredoc. I use heredoc for much the same
reasons I like to separate data from logic in separate files. The
next best thing to importing text is to heredoc it in the script
itself. Also heredoc can be a quick & dirty way of roughing out a
script to get the logic right before exporting the text to a separate file.
Another commenter in this thread is correct: you can't get away with
referring to an array variable in heredoc without using {curly
braces} e.g. {$aArray['key']}. That and the fact that the
termination symbol has to be at the left margin are minor
disadvantages in my view, far outweighed by the difficulty in
accurately writing and reading complex concatenations.
When I first started using PHP I thought that each heredoc label had
to be unique. Turns out that's not true, and now I use the simple shorthand:
$sResult = <<<_
Some text.
_;

Paul

I'm not dissing heredoc syntax, it has its uses (now and again) but it's
far from "clean", especially when embedded deep in classes - the major
cause being the delimeters insistance on being at the very start of the
line. It's just *not* pretty IMHO. Certainly not girl code [1]
The frowning surely would be at the mixing of logic and presentation,
regardless how that mix happens (heredoc, echo, jumping in and out of
PHP tags, sprintf, etc).
Cheers,
Rich

Classes? PHP is the absolute worst language to do OO programming in.
If you like OO, move on to ruby or python, you'll be much happier. Or
you can wait around until PHP fully (d)evolves into Java.

All parts of a heredoc statement do not have to be right justified,
only the closing line.

Mmmm.. girls.. coding.. :)

Sounds like you got MVC-itis. PHP can't really help with that since
it's a templating language.
Try Rubyonrails, it's the best cure for the MVC itch.
regardless how that mix happens (heredoc, echo, jumping in and out of

I love me some heredoc syntax:
#!/usr/bin/env perl -w
$x = <<END;
hello world!
END
print $x;
#!/usr/bin/env ruby -w
x = <<END
hello world!
END
puts x
#!/usr/bin/env python
x = """
hello world!
"""
print x

You sissy, Ruby and Python suck. One baseless statement deserves
another. Feel free to back up your statement with verifiable proof.

Unlikely.

Except that it's a PAC framework, not MVC, like the vast majority of web apps
frameworks out there in any language. The web just doesn't lend itself to
MVC. Sun just likes to get their terminology wrong and confuse everyone for
the next decade.

I am new to PHP programming and need some help. I have an image that i
have show up each May for the month with $mymonth = date("m", mktime()),
but i want to set up a date range for it to show up. Ex. 4-13 to 5-13
each year. How can I do that? Any help would be great.

One way would be to do this:
<?
if(date("md") > 413 && date("md") < 513) {
// Display image

There are loads of ways, but hopefully as you're new to PHP this one
will be easy to follow and make sense:
$start_date = strtotime('4 August 2007');
$end_date = strtotime('9 October 2007');
$current = time();
if ($current >= $start_date && $current <= $end_date)
{
// Do whatever should only happen between the
// 4th of August and the 9th of October here
}
strtotime() is extremely powerful / useful, and well worth reading about:

Ben, make sure whatever method you use, you use the operator
combinations >= and <= as Richard just showed you. I had forgotten to do
that, which would mean (in my example) that the 13th of April and 13th of
May of each year would not be counted, only 14 April through 12 May of any
given year. Also, expanding on Richard's example, you can make it dynamic
per year by combining the strtorime() and date() functions, so you wouldn't
have to update your code annually. However, this would only work if both
dates were within the same (current) year at the time the script was
executed:
<?
$start_date = strtotime('4 August '.date("Y"));
$end_date = strtotime('9 October '.date("Y"));
$current = time();
if ($current >= $start_date && $current <= $end_date)
{
// Do whatever should only happen between the
// 4th of August and the 9th of October here
}
?>

If I take out this bit of code from the above code:

You've got missing { } around your if blocks. You also could make the

code a lot more tidy / easy to read. Try the following (it replaces
entirely the code you emailed me, swap all of it for this)
<?php
$mymonth = date('m');
// novenmber is pancreatic cancer month
if ($mymonth == 11)
{
?>
<tr><td align="center" bgcolor="#ffffff"><a
href="http://pancan.com/Patient/pancreatic.html"; target="_blank"><img
src="../images/ads/pancanNov_banner.jpg" width="777" height="182"
border="0"></a></td>
</tr>
<?php
}
$start_date = strtotime('13 April '.date("Y"));
$end_date = strtotime('13 May '.date("Y"));
$current = time();
if ($current >= $start_date && $current <= $end_date)
{
?>
<tr><td align="center" bgcolor="#ffffff"><a
href="../images/passportad/mothersdayBanner.jpg" target="_blank"><img
src="../images/passportad/mothersdayBanner.jpg" width="771" height="112"
border="0" /></a></td>
</tr>
<?php
}
?>
Cheers,
Rich

"A key may be either an integer or a string. If a key is the standard
representation of an integer, it will be interpreted as such (i.e. "8" will
be interpreted as 8, while "08" will be interpreted as "08")."
I was always under the impression that using:
$_SERVER[HTTP_USER_AGENT] or $foo[myindex]
Was "bad" compared to the proper way of:
$_SERVER['HTTP_USER_AGENT'] or $foo['myindex']
Just like it's:
define('MYTHING', true);
not
define(MYTHING, true);
(again, note the ' marks)
http://us2.php.net/manual/en/function.define.php
http://us2.php.net/manual/en/language.constants.php
"If you use an undefined constant, PHP assumes that you mean the name of the
constant itself, just as if you called it as a string (CONSTANT vs
"CONSTANT"). An error of level E_NOTICE will be issued when this happens.
See also the manual entry on why $foo[bar] is wrong (unless you first
define() bar as a constant). If you simply want to check if a constant is
set, use the defined() function."
So, I think you're relying upon a little work that PHP does for you in that
an undefined CONSTANT is turned into a STRING i.e. "bad". Personally, I
*hate* that it does this work, and would love to see a little stricter
parsing done and throw a fatal error if you try to use an undefined
constant.

You can do this yourself.

True, but notice he's using it inside a heredoc string and the rules
are slightly different for string parsing.
http://www.php.net/manual/en/language.types.string.php#language.types.string.parsing
Whereas outside a string, $foo[myindex] will give you a notice and
$foo['myindex'] is OK; Inside a string, $foo[myindex] will give you no
notice and $foo['myindex'] will give you a parse error.
The manual suggests that $foo[myindex] is treated the same inside a
string as outside - if 'myindex' is defined as a constant then that is
what's used as the index. This doesn't seem to be born out by reality.
<?php
error_reporting(E_ALL);
$test = array(
'FOO' => 'Bareword',
'BAR' => 'Constant'
);
define( 'FOO', 'BAR');
print "\$test[FOO]: FOO is interpreted as a $test[FOO]\n";
print "{\$test[FOO]}: FOO is interpreted as a {$test[FOO]}\n";
print "{\$test['FOO']}: FOO is interpreted as a {$test['FOO']}\n";
?>
$ php5 test.php
$test[FOO]: FOO is interpreted as a Bareword
{$test[FOO]}: FOO is interpreted as a Constant
{$test['FOO']}: FOO is interpreted as a Bareword

As this one continues!
Looking for a program that will help me monitor sessions/user/page access to
upload to my server to help me debug what is going wrong.
I must have some conflict going on somewhere in the background and maybe
some monitoring program will help me get to the root of the issue.
