include('simple_html_dom.php');
$url = 'https://mangaarabteam.com/manga/yuan-zun/94/';
$html = file_get_html($url);
foreach($html->find('img') as $e){
$image_links = $e->src;

this code in : index.php
foreach( $images_url as $image ){
print_r($image);
}
i want the output $image multiple images not only on image

Try the below code.
you're setting your empty array($images_url = array();) inside the foreach it should be before the foreach.
$url = 'https://mangaarabteam.com/manga/yuan-zun/94/';
$html = file_get_html($url);
$images_url = array();
foreach($html->find('img') as $e){
$image_links = $e->src;
array_push( $images_url, $image_links);
}
foreach( $images_url as $image ){
print_r($image);
}

Use 'foreach' in script

I'm trying to write a script that list all the image URL from an specific URL. I used foreach in order to scan several pages, but I think os not working well.
This is my code:
<?php
include('simple_html_dom.php');
$array = array($page, $page2);
$page = "https://www.dllo.dev";
$page2 = "https://www.dllo2.dev";
$html = new simple_html_dom();
$html->load_file($array);
$images = array();
foreach($html->find('img') as $element) {
$images[] = $element->src;
}
reset($images);
echo "URL $array:<br /><br />";
foreach ($images as $out) {
$url = "$base$out";
echo "$url,&nbsp";
}
It's partially working, but only with the first URL ($page)... Any idea?
:D

how to alter and then show attributes in html with php

in my table, I have a row that contains a string like this:
<p>hello</p><p>this is patrick</p><p><img src="/assets/img/myface.jpg" width="320" height="320"/></p>
and I want to give the <img> tag an alt attribute. I've got quite close now but somehow my code still shows 2 <img> tags although the string only has 1. can anyone tell me what I'm doing wrong?
this is my code so far:
$str = '<p>hello</p><p>this is patrick</p><p><img src="/assets/img/myface.jpg" width="320" height="320"/></p>';
$new_html = '';
$dom = new DOMDocument();
$dom->loadHTML($str);
$content = $dom->getElementsByTagName('*');
foreach ($content as $i => $node)
{
if ($node->nodeName == 'html' || $node->nodeName == 'body')
{
continue; // dont need to process these tags, right?
}
if ($node->nodeName == 'img')
{
$img_src = $node->getAttribute('src');
$path_arr = explode('/', $img_src);
$filename = $path_arr[count($path_arr)-1]; // myface.jpg
$alt = 'blah';
$node->setAttribute('alt', $alt);
}
echo $dom->saveXML($node);
}
$content = $dom->getElementsByTagName('img');
foreach ($content as $node) {
$img_src = $node->getAttribute('src');
$filename = basename($img_src);
$node->setAttribute('alt', $filename);
}
echo $dom->saveHTML();
Loop only through images with $content = $dom->getElementsByTagName('img');
Move $dom->saveHTML(); after lthe loop.
Get filename with $filename = basename($img_src);
The slightly changed code below does the work. It only gets the img tags and saves the HTML outside the loop. Note that I changed the way that HTML was loaded, to not include the wrapper tags.
<?php
$str = '<p>hello</p><p>this is patrick</p><p><img src="/assets/img/myface.jpg" width="320" height="320"/></p>';
$new_html = '';
$dom = new DOMDocument();
$dom->loadHTML($str, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
$content = $dom->getElementsByTagName('img');
foreach ($content as $i => $node)
{
$img_src = $node->getAttribute('src');
$path_arr = explode('/', $img_src);
$filename = $path_arr[count($path_arr)-1]; // myface.jpg
$alt = 'blah';
$node->setAttribute('alt', $alt);
}
echo $dom->saveHTML();
The problem is that when you use
echo $dom->saveXML($node);
in the loop, it will output for various tags and so the output is not the end result, but a combination of other parts of the document.
Try changing it to
echo $node->nodeName."=>".$dom->saveXML($node).PHP_EOL;
to see what it does.
You could just remove the current echo and add
echo $dom->saveXML();
after the end of the loop.
Alternatively, if you just want to process the <img> tags, you can limit the loop more specifically...
$content = $dom->getElementsByTagName('img');
foreach ($content as $i => $node)
{
$img_src = $node->getAttribute('src');
$path_arr = explode('/', $img_src);
$filename = $path_arr[count($path_arr)-1]; // myface.jpg
$alt = 'blah';
$node->setAttribute('alt', $alt);
}
echo $dom->saveXML();

Printing thumbnails using simpleXML parse - how to return all?

I have looked for this answer to this question on here but I can't seem to find anything which is relevant to this particular issue.
I am currently using simpleXML to parse an RSS feed, in order to return thumbnail images by going through the nodes to parse "media:thumbnail". I have managed to do this and return all thumbnail URLs, so I know that I am getting to the right content, like so:
<?php
$url = "http://feeds.bbci.co.uk/news/rss.xml?edition=uk";
$xml = simplexml_load_file($url);
foreach($xml->channel->item as $item) {
$media = $item->children('media', 'http://search.yahoo.com/mrss/');
foreach($media->thumbnail as $thumb) {
echo $thumb->attributes()->url;
}
}
?>
This echos all the image urls. But when I store this in to a variable and try to echo this later as the img src, it only returns one image, rather than all:
<?php
$url = "http://feeds.bbci.co.uk/news/rss.xml?edition=uk";
$xml = simplexml_load_file($url);
foreach($xml->channel->item as $item) {
$media = $item->children('media', 'http://search.yahoo.com/mrss/');
foreach($media->thumbnail as $thumb) {
$image = $thumb->attributes()->url;
}
}
?>
<div><img src = <?php echo $image; ?> /></div>
How can I echo all of the URLs in to individual images? Thanks for looking.
Since you're getting and expecting multiple image urls, might as well store them inside an array:
$images_container = array();
foreach($xml->channel->item as $item) {
$media = $item->children('media', 'http://search.yahoo.com/mrss/');
foreach($media->thumbnail as $thumb) {
$image = $thumb->attributes()->url;
$images_container[] = (string) $image;
}
}
echo '<pre>', print_r($images_container, 1), '<pre>';
Sample Output
Now of course, if you want to process those array of string image urls, then just use and process the container:
<?php foreach($images_container as $url): ?>
<div><img src="<?php echo $url; ?>" alt="" /></div>
<?php endforeach; ?>
Pictures
Try xpath.
$url = "http://feeds.bbci.co.uk/news/rss.xml?edition=uk";
$xml = simplexml_load_file($url);
$xml->registerXPathNamespace( 'media', 'http://search.yahoo.com/mrss/' );
// get only thumbnails of specified width
$xpath = $xml->xpath( '//media:thumbnail[#url and #width=144]' );
/**
* The above xpath will get only thumbnails of width 144
*/
foreach( $xpath as $node ) {
echo '<div><img src="' . $node['url'] . '" /></div>';
}
Hope that helps.

PHP & Lightbox (href in for loop links to last file of lightbox set)

EDITED: Debugged some of the code but issue persists:
The issue i'm having with the following code is that the link always takes me to the last image in the set. I've tried reversing the array of photo's but it had no effect. Any help would be appreciated.
Thanks.
<?php
$dir = 'pic';
$max_albums=9;
$albums = array_diff(scandir($dir),array('..', '.', 'thumbs'));
foreach ($albums as $album) {
$albumdir = $dir.'/'.$album;
$coverdir = $albumdir.'/thumbs';
$thumbs = array_diff(scandir($coverdir),array('..', '.'));
//re-index $thumbs
$thumbs = array_values($thumbs);
//1 random cover image from each album
$rnd_min = 0;
$rnd_max = count($thumbs)-1;
$rnd_i = mt_rand($rnd_min, $rnd_max);
$covers = $thumbs[$rnd_i];
//re-index $covers
echo $rnd_i.'<br>';
//populate hrefs
$photos = array_diff(scandir($albumdir),array('..', '.', 'thumbs'));
//re-index $photos
$photos = array_values($photos);
foreach ($photos as $photo) {
echo '<a href="'.$albumdir.'/'.$photo.'" data-lightbox="'.$album.'">';
}
//display cover images
echo '<img src="'.$coverdir.'/'.$covers.'" class="img-responsive"></a>';
}
?>
hmmm try reversing scandir
$photos = array_diff(scandir($albumdir,1),array('..', '.', 'thumbs'));
Not a very elegant solution but it seems to work:
<?php
$dir = 'pic';
$max_albums=9;
$albums = array_diff(scandir($dir),array('..', '.', 'thumbs'));
foreach ($albums as $album) {
$albumdir = $dir.'/'.$album;
$coverdir = $albumdir.'/thumbs';
$thumbs = array_diff(scandir($coverdir),array('..', '.'));
//re-index $thumbs
$thumbs = array_values($thumbs);
//1 random cover image from each album
$rnd_min = 0;
$rnd_max = count($thumbs)-1;
$rnd_i = mt_rand($rnd_min, $rnd_max);
$covers = $thumbs[$rnd_i];
//populate hrefs
$photos = array_diff(scandir($albumdir),array('..', '.', 'thumbs'));
//re-index $photos
$photos = array_values($photos);
$countphoto = 0;
foreach ($photos as $photo) {
if ($countphoto==0) {
echo '<a href="'.$albumdir.'/'.$photo.'" data-lightbox="'.$album.'">'."\n";
//display cover images
echo '<img src="'.$coverdir.'/'.$covers.'" class="img-responsive"></a>';
}
else {
echo ''."\n";
}
$countphoto++;
}
}
?>
So i solved this issue with a simple if $countphotos==0 statement within the foreach ($photos as $photo) loop, if 0, it would display the thumbnail, else it would just output anchors to the other imgs.
I've also done away with the random thumbnail as cover, and just pulled the first thumbnail of the set.
I now another issue, but I will make a separate thread for that.
Thanks!

How to turn variable feed to array?

I want to turn the variable into an array so I can store more than one feed?
<?php
error_reporting(0);
$feed_lifehacker_full = simplexml_load_file('http://feeds.gawker.com/lifehacker/full');
$xml = $feed_lifehacker_full;
//print_r($xml);
foreach ($xml->channel->item as $node){
$title = $node->title;
$link = $node->link;
$link = explode('/', $link);
$link = $link[8];
$url = $node->url;
$description = $node->description;
$pubDate = $node->pubDate;
preg_match_all('#(http://img[^\s]+(?=\.(jpe?g|png|gif)))#i', $description[0], $images);
$images = $images[0][1] . '.jpg';
if($images == '.jpg'){
//uncomment to show youtube articles
//$images = "http://placehold.it/640x360";
//echo "<a href='page2.php?a=$link' title='$title'><img src='$images' /></a><br>";
} else {
//article image
$images . '<br>';
echo "<a href='page2.php?a=$link' title='$title'><img src='$images' /></a><br>";
}
}
How can I change this to load to arrays,
$feed_lifehacker_full = simplexml_load_file('http://feeds.gawker.com/lifehacker/full');
$xml = $feed_lifehacker_full;
The script is just gathering the image of an rss feed and linking to a page, if you see how it can be done more efficiently feel free to say
it is possible to encode the result given as json and by decoding it it will return you an array
$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
$array = json_decode($json, TRUE);
