Sample XML:
<root>
<ratings>3</ratings>
<ratings>5</ratings>
<ratings>7</ratings>
</root>
The following code is the basis for my small application, it works as would be expected:
<?php
// $xml is some simplexml object
sizeof($xml->ratings); //3
foreach($xml->ratings as $rating){
echo($rating->value."::"); //this echoes all 3 rating values: 3::5::7
}
?>
This next code, which I would normally consider to be equivalent is not. And I have no idea why:
<?php
// $xml is some simplexml object
$ratings = $xml->ratings;
sizeof($ratings); //3, all is well so far
foreach($ratings as $rating){
echo($rating."::");
/*this echoes a never-ending list of ratings,
looking like 3::5::5::5::5::5::5::5...... */
}
?>
My feeling is that the assignment operator is casting the array of simplexml objects (ratings objects) as something odd, but have no clue as to how.
Any ideas?
Other little hints:
var_dump($xml);
/* Output is:
object(SimpleXMLElement)#7 (1) {
["ratings"]=>
array(3) {
[0]=>
string(1) "3"
[1]=>
string(1) "5"
[2]=>
string(1) "7"
}
}
*/
var_dump($ratings);
/* Output is:
object(SimpleXMLElement)#6 (1) {
[0]=>
string(1) "3"
}
*/
