I am using PHP version 4.2.3.  This is old,
but I cannot upgrade.

I came across a strange limitation which is
puzzling me.  The following test program:

<?php
//  This PHP file tests the use of count() as an array index
     $anArray[1] = "This is element one";
     $anArray[2] = "This is element two";
     $anArray[3] = "This is the last element";
//
     echo "$anArray[count($anArray)]\n";
?>

produces the error message:
Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, 
expecting ']' in CountTest.php on line 7

Why is using count() as an array index not
allowed?

This is no big deal as the work around is
trivial; just replace the last line with:

     $lastIndex = count($anArray);
     echo "$anArray[$lastIndex]\n";

However, it is puzzling.

Many thanks,
Martin

That's not what the error message says.

Which produces a notice "Undefined offset: ..."

No. Read about "interpolation" in PHP. (As a hint: PHP can't isolate the 
function name.)

What's not allowed is using a function call as part of a variable 
translation inside a string.

Note that by default, array indexes start at 0.

<?php
$arr = array("first","middle","last");
$len = count($arr);
echo "element {$len} is {$arr[$len]}\n";
?>

Generates output:

You can not use a function call within a quoted string.

You should use:

echo $anArray[count($array)] . "\n";

[Note: in "standard" arrays (indexing starts at 0), count($some_array) 
will be an undefined index.]

Actually, you can easily use a function call within a quoted string, but 
since it is not a simple variable, you need to use curly braces, i.e.

<?php
     $anArray[1] = "This is element one";
     $anArray[2] = "This is element two";
     $anArray[3] = "This is the last element";
     echo "{$anArray[count($anArray)]}\n";
?>

prints "This is the last element" (without the quotes, of course).

Be aware, though - the typical array in PHP starts counting at 0, not 1. 
  So an array of 3 elements would be numbered 0, 1 and 2.  In this case, 
an element with an index of 3 (count($anArray)) is not set (and will 
give a warning if you try to use it).

You need to get used to this idea; it's used throughout PHP.

Oh how I have come to love those curly braces.. :)

The test code I posted was taken from my
application in which I deliberately start my
array with [1].  This is because the array
holds numbered sections of an FAQ, and it
makes more sense to have Section 1 in array
element [1], etc.

Actually, I think it's a bad way to do things.  What happens if you want 
to add a new section - or delete one?  You'll have to change your code, 
which should never be the case.

A better way is to hold the information in a database.

Please compare:

$anArray[count($array)] . "\n";

"{$anArray[count($anArray)]}\n";

You see the difference? Your suggestion is longer (even whitespaces
which can me omitted) and totally unreadable for people you are not
familiar with this.

ACK.

Just because something is possible does not mean you have to use it ;-)
Curly braces should only be used for code blocks and not to replace
string concatenation.

   People that aren't familiar with this are mostly people that simply 
jump in to PHP without reading much documentation. Which is possible but 
people should end up reading at one of the PHP mirrors at some point. In 
this case:

http://us.php.net/manual/en/language.types.string.php

....which explains all the different ways and reasons why.

   It's a little more than possible... it was designed this way. It's 
not a replacement for string concatenation, it is used (in this context) 
for variable expansion within strings. If you don't want to use curly 
brace syntax, then do it the long way, it's your choice. Me personally, 
I find curly brace syntax much more readable than alot of '.'s and '/' 
escapes like alot of people use.

being an old C hacker I simply use (s)printf, lots of %s's and stick all 
the variables in a parameter list.

the nice thing about that is that - especially if using POST or GET 
variables you can counter PHPs execrable lack of string typing using 
'%d' and KNOW that whatever malformed crap is in the variables you will 
get a number or nothing at all.

Yup, I used an extra pair of braces.  Just because YOU don't like it 
doesn't mean it's a bad idea.

No, I will not need to change my code.  I
am using an array as a replacement for a
database.  Here is a snippet of my file
faqData.php to give you the idea:

//  Set data to identify Web page, and set prev and next anchors
//  Note that the first set must have index explicitly set to [1]
     $tempIndex = 1;
     $dataHref[$tempIndex] = "Ambisonic/faq_section01.html";
     $dataAnchorText[$tempIndex] = "1. Where can I get this FAQ?";
     $dataCompleteText[$tempIndex] = "1. <a href=\"#SECTION1\">Where can 
I get this FAQ?</a>";
     $dataSplitText[$tempIndex] = "1. <a rel=\"section\" 
href=\"$dataHref[$tempIndex]\">Where can I get this FAQ?</a>";

     $tempIndex++;
     $dataHref[$tempIndex] = "Ambisonic/faq_section02.html";
     $dataAnchorText[$tempIndex] = "2. Corrections to the FAQ";
     $dataCompleteText[$tempIndex] = "2. <a 
href=\"#SECTION2\">Corrections to the FAQ</a>";
     $dataSplitText[$tempIndex] = "2. <a rel=\"section\" 
href=\"$dataHref[$tempIndex]\">Corrections to the FAQ</a>";

Yes, which means if you need to change your FAQs you need to change this 
code.

It is.

The form

"text {...something...} text"

is generally the same as

'text' . something . 'text'

So:

echo 'This is the result: '.$myclass->result;

Is longer than

echo "This is the result: {$myclass->result}";

And why do i have to escape '/'? Seems have missed something ;-)
