If the problem is not the obvious one
i.e. $x = $my_array[]; which is wrong because empty [] are only for
setting, there can be this case(as posted by [18 Apr 2006 7:03pm UTC]
oliver at samera dot com dot py)
it is not a bug, but a way how PHP treats calling of variables
simple test case
class A {
public $field = array();
public $field2 = array();
public function AddToField($fieldname, $item){
$this->$fieldname[] = $item;
}
}
this throws an error because PHP is trying to read fieldname WITH the
parenthsis
so the workaround is to put
$this->{$fieldname}[]=$item and it is working - it just helps compiler
what did you ment with $fieldname.

I've had the same problem. It reported the error in line 26, but the
line was ok. I often try entering empty lines - it reveals if the error
is somewhere else. The problem with this error is just trying to read
something like this:
$somename[]
if you try:
$this=$thatarray[];
without putting something between [] you get this error.
Everything would be ok if PHP reported it in correct line. Please fix
that! It would save people ages of looking the code through!

PHP 4.3.4
I got this error when mistakenly used "return $variable[];" instead of
"return $variable" in a user defined function.

I've just had the same problem, from changing a variable from global,
to class specific. After some confusion I realised I forgot to remove
the $, just like in your example:
$this->$resultado_array[] should be
$this->resultado_array[]
and then it all works fine.

Seems to be a class related bug, here is a simple test-case:
<?php
// php 4.3.9 - CentOS 4.3 - [EMAIL PROTECTED] - 18-apr-2006
//
-----------------------------------------------------------------------------
class cache_db {
var $resultado_array;
function cache_db() {
$this->$resultado_array = array();
}
// abre un archivo y lo carga en memoria
function cache_open() {
$archivo_array = array(array('1'), array('2'), array('3'));
$resultado_array = array();
foreach($archivo_array as $linea) {
$resultado_array[] = $linea;
$this->$resultado_array[] = $linea;
}
}
}
// without a class
$archivo_array = array(array('1'), array('2'), array('3'));
$resultado_array = array();
foreach($archivo_array as $linea) {
$resultado_array[] = $linea;
}
?>

I got the same strange Fatal error (using Windows XP, PHP PHP 5.0.4):
Fatal error: Cannot use [] for reading in ... on line 82
[php]
if ($insert->check($_POST['value']) === FALSE)
{
$error[] == 'Error'; // line 82
}
[/php]
Zend Developer didn't give any warnings so there shouldn't be any
syntax mistakse in that PHP file.
