Bug description: arrayAcces & using $this
Description:
------------
Class inherited of class implemented ArrayAccess have problems with using
$this['some' . $var] = $var . 'str';
if $var passed as method parameter.
Seems this is a memory problem.
Look at the 3 last entries in rtfHelperArray::haStore.
Reproduce code:
---------------
<?php
abstract class rtfHelperArray implements arrayAccess {
private $haStore = array ();
final public function offsetExists ($offset) {
return true;
}
final public function offsetGet ($offset) {
if (array_key_exists ($offset, $this->haStore)) {
return $this->haStore[$offset];
} else {
$temp = NULL;
return $temp;
}
}
final public function offsetSet ($offset, $value) {
$this->haStore[$offset] = $value;
return true;
}
final public function offsetUnset ($offset) {
unset ($this->haStore[$offset]);
return true;
}
}
error_reporting (E_ALL);
class test extends rtfHelperArray {
public function doTest ($idx) {
$this[$idx] = $idx;
echo $idx, ' : ', $this[$idx], "\n";
$this[$idx . '-2'] = $idx . '-2';
echo $idx . '-2', ' : ', $this[$idx . '-2'], "\n";
$this['3-' . $idx] = $idx . '-333';
echo '3-' . $idx, ' : ', $this['3-' . $idx], "\n";
$this['4-' . $idx] = $idx . '-4444';
echo '4-' . $idx, ' : ', $this['4-' . $idx], "\n";
$this['5-' . $idx] = $idx . '-5';
echo '5-' . $idx, ' : ', $this['5-' . $idx], "\n";
var_dump ($this);
}
}
$o = new test ();
$o->doTest ('idx');
?>
Expected result:
----------------
idx : idx
idx-2 : idx-2
3-idx : idx-333
4-idx : idx-4444
5-idx : idx-5
object(test)#1 (1) {
["haStore:private"]=>
array(5) {
["idx"]=>
string(3) "idx"
["idx-2"]=>
string(5) "idx-2"
["3-idx"]=>
string(7) "idx-333"
["4-idx"]=>
string(8) "idx-4444"
["5-idx"]=>
string(5) "idx-5"
}
}
Actual result:
--------------
idx : idx
idx-2 : idx-2
3-idx :
4-idx : idx-4444
5-idx :
object(test)#1 (1) {
["haStore:private"]=>
array(5) {
["idx"]=>
string(3) "idx"
["idx-2"]=>
string(5) "idx-2"
["idx-3"]=>
string(7) "test 3"
["4-idx"]=>
string(8) "idx-4444"
["idx-5"]=>
string(5) "test "
}
}
