PHP XML删除元素

Question

My xml looks like this:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<images>
    <pic>
        <image>54</image>
        <descr>Image 1</descr>
    </pic>
    <pic>
        <image>32</image>
        <descr>Image 2</descr>
    </pic>
    <pic>
        <image>47</image>
        <descr>Image 3</descr>
    </pic>
</images>

I want to remove one element, for example second pic (image 32). Using this code, but it's not working.

$xml = simplexml_load_file('../../images.xml');

$target = false;
$i = 0;
foreach ($xml->pic as $m) {
  if ($m['image']=='32') { $target = $i; break; }
  $i++;
}
if ($target !== false) {      //$target always be $false
  unset($xml->pic[$target]);
}

echo $xml->savexml();

Thanks for any advice.

Observations

$m is object not array so $m['image'] should be changed to $m->image

Change $target = false; to $target = 0 ;

Example

$xml = simplexml_load_file ( '1.xml' );
$target = 0;
$i = 0;
foreach ( $xml->pic as $m ) {
    if ($m->image == '32') {
        $target = $i;
        break;
    }
    $i ++;
}

if ($target !== false) {
    unset ( $xml->pic [$target] );
}
echo $xml->savexml ();
