This is a scaled down example of something I'm doing in some code. The
results are very funky. I guess I could understand this happening if
$two was out of scope when print_r($this) was called in
One()...actually no I couldn't.
<?php
Class One {
function One() {
$this->test = array();
$two = new Two( $this );
print_r( $this );
}
function set( $index, $value ) {
$this->test[$index] = $value;
}
}
Class Two {
var $one = null;
function Two( &$one ) {
$this->one = $one;
$this->one->set( 'foo', 1 );
print_r($this);
}
}
$obj = new One;
?>
OUTPUT:
two Object
(
[one] => one Object
(
[test] => Array
(
[foo] => 1
)
)
)
one Object
(
[test] => Array
(
)
)
This only happens if you assign the reference passed to the second
class as an instance variable. If you call the reference directly, the
variable persists. ie:
<?php
Class One {
function One() {
$this->test = array();
$two = new Two( $this );
print_r( $this );
}
function set( $index, $value ) {
$this->test[$index] = $value;
}
}
Class Two {
var $one = null;
function Two( &$one ) {
$one->set( 'foo', 1 );
}
}
$obj = new One;
?>
OUTPUT:
one Object
(
[test] => Array
(
[foo] => 1
)
)
Any Ideas?
