Memory leak when setting attributes as in example (#Example 2134. Setting values)
This probably goes unnoticed in web scripts (unless you do a LOT of xml manipulations), but I ran
into this in my standalone script that processes a large number of XML files.
The following code will eat up memory quite fast:
<?php
include 'example.php';
while (true) {
$xml = new SimpleXMLElement($xmlstr);
$xml->movie[0]->characters->character[0]->name = 'Miss Coder';
}
?>
while this seems to behave correctly:
<?php
include 'example.php';
while (true) {
$xml = new SimpleXMLElement($xmlstr);
$c = $xml->xpath("//character");
$c[0]->name = 'Miss Coder';
}
?>
This looks like bug #38604, and I just confirmed that in 6.0.0-dev (on Windows at least) it is
fixed. It is NOT fixed in 5.2.1 or 5.2.2-dev (2/21 build), so for 5.2 users, use the second form
to avoid leaks.
