PHP code generates PHP code for ubuntu to automatically switch wallpaper xml files

Copy the code The code is as follows:

/*
* Generate ubuntu automatic wallpaper switching xml file
*/
//Picture directory
$dir = '/home/yuxing/background';
$hd = opendir($dir) or die('can not open dir');
$files = array();
while($file = readdir($hd)) {
$tem = "$dir/$ file";
if (is_file($tem) && in_array(strtolower(substr(strrchr($file,'.'), 1)), array('jpg', 'gif')))
$files[] = $tem;
}
closedir($hd);
unset($file);
$xw = new xmlWriter();
$xw->openMemory();
$xw->setIndent(true);
$xw->setIndentString(' ');
$xw->startDocument('1.0', 'utf-8');
$xw->startElement('background');
$xw->startElement ('starttime');
$xw->writeElement('year', '2000');
$xw->writeElement('month', '01');
$xw->writeElement('day ', '01');
$xw->writeElement('hour', '00');
$xw->writeElement('minute', '00');
$xw->writeElement(' second', '00');
$xw->endElement();
$count = count($files);
for ($i=0; $i<$count; $i++) {
$xw- >startElement('static');
//$xw->writeElement('duration', '1795.0');
$xw->writeElement('duration', '30.0');
$xw-> ;writeElement('file', $files[$i]);
$xw->endElement();
$xw->startElement('transition');
$xw->writeElement('duration', '5');
$xw->writeElement('from', $files[$i]);
$xw->writeElement('to', isset($files[$i+1]) ? $ files[$i+1] : $files[0]);
$xw->endElement();
}
$xw->endElement();
$xml = $xw->outputMemory(true) ;
//Generate file
$hd = fopen($dir . "/yuxing.xml", 'wb');
fwrite($hd, $xml);
fclose($hd);
echo 'ok';
?>

The above introduces the PHP code to generate the PHP code for Ubuntu to automatically switch the wallpaper xml file, including the content of PHP code. I hope it will be helpful to friends who are interested in PHP tutorials.
