I have this error: Object of class DOMDocument could not be converted to string
I'm trying to parse web page to get text inside a div
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$html = curl_exec($ch);
$dom = new DOMDocument();
$dom->loadHTML($html);
$table = $dom->getElementById('mostra')> textContent; //DOMElement
echo $table;
This is html element:
<div id="mostra">Hello<img src="file.png"></div>
I want to print Hello
How can i solve it ?
Thanks a lot and sorry for my english

Try to use this function to find text between two element
I am using this code to pull data to my site from an external source, and am wondering how I would parse this using PHP.
include(app_path().'/Includes/simple_html_dom.php');
$html = file_get_html("http://www.teamsideline.com/sites/parkfun/schedule/153461/Adult-Outdoor-Soccer-Mens-Competitive", NULL, NULL, NULL, NULL);
$data = array();
foreach($html->find("tbody tr") as $tr){
$row = array();
foreach($tr->find("td") as $td){
/* enter code here */
$row[] = $td->plaintext;
}
$data[] = $row;
}
I am trying to extract the standings data in particular, and recreate the standings table on my page with the data from this site. How can I achieve this?
Seems like the website doesn't allow file_get_html(). Atleast for me it's not working.
Anyway, you could use cUrl to get the html string and then parse that string using str_get_html().
To display the table on your website, simply echo the found data like this:
$url = 'http://www.teamsideline.com/sites/parkfun/schedule/153461/Adult-Outdoor-Soccer-Mens-Competitive';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$result = curl_exec($curl);
$html = str_get_html($result);
$data = "";
$data .= "<table width='100%'>";
foreach($html->find("tbody tr") as $tr){
$data .= "<tr>";
foreach($tr->find("td") as $td){
$data .= "<td style='border: 1px black solid'>";
$data .= $td->plaintext;
$data .= "</td>";
}
$data .= "</tr>";
}
$data .= "</table>";
echo $data;
I am using two JSON feed sources and PHP to display a real estate property slideshow with agents on a website. The code was working prior to the feed provider making changes to where they store property and agent images. I have made the necessary adjustments for the images, but the feed data is not working now. I have contacted the feed providers about the issue, but they say the problem is on my end. No changes beyond the image URLs were made, so I am unsure where the issue may be. I am new to JSON, so I might be missing something. I have included the full script below. Here are the two JSON feed URLs: http://century21.ca/FeaturedDataHandler.c?DataType=4&EntityType=2&EntityID=2119 and http://century21.ca/FeaturedDataHandler.c?DataType=3&AgentID=27830&RotationType=1. The first URL grabs all of the agents and the second grabs a single agent's properties. The AgentID value is sourced from the JSON feed URL dynamically.

Try this code to fix the JSON:

$invalid_json = file_get_contents($url);
$json = preg_replace("/([{,])([a-zA-Z][^: ]+):/", "$1\"$2\":", $invalid_json);
var_dump($json);
All your keys need to be double-quoted
JSON on the second URL is not a valid JSON, that's why you're not getting the reults, as PHP unable to decode that feed.
I tried to process it, and get this error
Error: Parse error on line 1:
{Props: [{Address:"28
-^
Expecting 'STRING', '}'
Feed image for first URL
and here is view of 2nd URL's feed
as per error for second feed, all the keys should be wrapped within " as these are strings rather than CONSTANTS.
e.g.
Props should be "Props" and all other too.
EDIT
You need to update your functionand add this one(formatJSON($json)) to your class

EDIT
I've tested that function, and it's working fine, may be there is something wrong with your function decode_json_string($json)
I've taken unclean json from second URL, and cleaning it here, and putting that cleaned json in json editor to check either it's working or not HERE
I'm trying to write a script to cURL a few pages from a password protected site.
The idea is to scrape information on submitted stock codes from their products database to generate and print out the results (eventually importing directly to my own database, but currently just printing the results on screen).
My function is as follows:
function LookupProduct($ItemCodes) {
//set a temp file name for the login cookie
$tmp_fname = "tmp/".md5(date('D F d')).".cookie";
$tmp_fname = realpath($tmp_fname);
//reset/declare the functions output
$return = '';
// build post data from form
$fields = array(
'UserName' => urlencode("username"),
'Password' => urlencode("password"),
);
$fieldString='';
foreach($fields as $key=>$value) {
$fieldString .= $key.'='.$value.'&';
}
rtrim($fieldString, '&');

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch,CURLOPT_COOKIEJAR, $tmp_fname);
curl_setopt($ch,CURLOPT_COOKIEFILE, $tmp_fname);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
//do the actual login, generate cookie
$result = curl_exec($ch);
//build array of codes to lookup
$codes=explode(",", $ItemCodes);
//lookup each code in the array
foreach($codes as $code) {
//set the product page to curl
$lookupUrl = "https://suppliers-website/product/".$code;
curl_setopt($ch,CURLOPT_URL, $lookupUrl);

echo "ItemCodes: ".$code;
echo LookupProduct($code);
}
The script can successfully log in, save a cookie, and get info from a page, but if I try to request multiple pages the script fails to work as intended, instead returning 3 instances of the same product. Did I fail to reset a variable somewhere? I've tried unsetting everything but I still just get the same product three times, as if my function only works once.
I got the site fully working and returning the information from the rss feed since the it return with website link how can i display the information from the link instead of redirect the user back to the original site?
<?php

use curl to read the info from link and publish it e.g.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $file);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
$result = curl_exec($ch);
curl_close($ch);
no need. you can add this code in your prog e.g.
<?php
$query = 'http://query.yahooapis.com/v1/public/yql?q=Select%20*%20from%20rss%20where%20url%3D%22http%3A%2F%2Fnestor.sunderland.ac.uk%2F~bf71wx%2FphpTest%2Fjquery.mobile-1.0.1%2520-%2520%25E8%25A4%2587%25E8%25A3%25BD%2Fjquery.mobile-1.0.1%2Fdemos%2Fdocs%2Frss%2FNews.xml%22%20&diagnostics=true';
