I am able to get the coding of a website with file_get_contents but I want to be able to get certain values out of the html. This piece of code is always the same but the value between the html tag changes from time to time. This is the HTML Code:
<div class="cheapest-bins">
<h3>Cheapest Live Buy Now</h3>
<table>
<tbody><tr>
<th>Console</th>
<th>Buy Now Price</th>
</tr>
<tr class=" active">
<td class="xb1">XB1</td>
<td>1,480,000</td>
</tr>
<tr class="">
<td class="ps4">PS4</td>
<td>1,590,000</td>
</tr>
<tr class="">
<td class="x360">360</td>
<td>---</td>
</tr>
<tr class="">
<td class="ps3">PS3</td>
<td>2,800,000</td>
</tr>
</tbody></table>
</div>
How would I go about getting the: 1,480,000 .. 1,590,000 .. --- and 2,800,000?
short answer:
find a css selector library such as https://github.com/tj/php-selector
then you could grab all td:last-child elements/innerhtml
for your specific example you could just just
preg_match_all('#<td>(.*?)</td>#', $html, $matches);

I have a query that returns me a long series of questions and answers. in my html page I have div that alternate with slider effect. so far everything is fine. at the moment I try to correctly display a question from the db bumps everything. why?
<div align=Center>
<br/>
<h1><?php echo $rowfirst['Cognome']." ".$rowfirst['Nome']; ?></h1>
<br/>
<div class="nivo-slider">
<div class="navigation"></div>
<?php
while($row = mysqli_fetch_array($result))
{
?>
<div id="nivo">
<div class="element" align=Center><h3>Anamnesi pregressa</h3>
<table class="w3-table w3-bordered " style="width:400px;padding:10px;" align="center">

<tr>
<th scope="row"><?php echo $row['testo'];}?></th>

The problem is the while. cycle. how can I solve it?
What you have will create malformed HTML.
In order to prevent malformed HTML, you should place your while () { and } where the tags matches like I have done with <tr> and </tr> shown below:
<?php
while($row = mysqli_fetch_array($result))
{
?>
<tr>
<th scope="row"><?php echo $row['testo'];?></th>
<td>risposta 1</td>
</tr>
<?php } ?>
That will fix your malformed HTML but the while statement may or may not be in the right place and without knowing exactly what you are trying to achieve you'll have to correct it from there. As for the slider you mentioned, you probably need to supply more information if this answer doesn't solve your issue.
I've been battling with this issue for a while now and can't find out why it's happening. I basically have a table which displays Woocommerce variations with each variation being in it's own row. The problem I have is when refreshing the page, the <th> row collapses and doesn't line up with the tbody.
Interestingly, if i change some of the css of the <th> in the console after the page loads, it fixes itself and lines up. The same applies If i open up the console after turn on 'Disable Cache' in the network tab and refresh the page.
My guess is the html is being loaded before the Woocommerce data is being added and doesn't have enough time to get the correct widths. However, this is a recent issue which has only just started happening.
Does anyone know what could cause this?
<table class="variations variations-grid" cellspacing="0">
<thead>
<tr>
<th><img class="camera-icon" src="/wp-content/uploads/2016/10/picture-holder.png"></th>

This is what is looks like broken:
This is what is looks like if i the disable cache OR change the css once it's loaded. This is how It should look.
I count more <td> in your <tbody> than <th> in your <thead>. Could this be the issue? Try to add empty <td> to match your <th> head count to test.
I am using file read functionality in one my application.
Sometimes I am getting the exception while opening and closing file because in filename I am getting as HTML string, what do I need to do to protect application or to identify this is not the correct name?

): failed to open stream: File name too long /srv/users/serverpilot/apps/php/public/application/controllers/Readfile.php 159
Your fopen function has a too long string in it. And I also think this cant be valid. You are looking for a file in ./upload/ with the name:
<table cellspacing="0" cellpadding="0"...
The name is too long and invalid. I think you pass a variable to the fopen function the content of the variable isn't correct.
I am working on a site that isn't SEO friendly. Specifically, the header.tpl is inserted automatically into every page, with no option to change it based on the content of the page. I.e., whether category = Bathroom or category = Kitchen, etc.
So I need an if/else command, but having trouble figuring it out in this instance, plus the change that goes along with it.
The code on the portfolio_category.php page is as follows, and what needs to change based on vf_category is parts/header.tpl (I can create Bathroomheader.tpl, Kitchensheader.tpl, etc so that relevant tpl has the relevant Title and Description tags for the page).
<?php
$vc_root_friendly = '.';
$vc_root_site = '.';
include_once("$vc_root_site/config.php");
include_once("$vc_includes_folder/IT.php");
$template_body = new HTML_Template_IT();
$template_body->loadTemplateFile("tpl_portfolio_category.html");
include_once("$vc_includes_folder/images.php");
if(!isset($_REQUEST['vf_category'])){
header("location:portfolio.php");
die();
}
//Show header
$template_header = new HTML_Template_IT();
$template_header->loadTemplateFile("parts/header.tpl",true,false);
$template_body->setVariable('header', $template_header->get());
//Show footer
$template_footer = new HTML_Template_IT();
$template_footer->loadTemplateFile("parts/footer.tpl",true,false);
$template_body->setVariable('footer', $template_footer->get());
$template_body->setVariable("image_category", $_REQUEST['vf_category']);
//Select photos for this category
etc.
Complicating things there is another page referenced in the code above:
tpl_portfolio_category.html
And this page too has its own header.tpl include:
<? include_once 'parts/header.tpl'; ?>
{header}
<table width="100%" cellspacing="0" cellpadding="0" border="0">
<tr>
<td class="main"><h1><span class="firstLetter">{image_category}</span></h1>
<p>

Any guidance would be appreciated! I'm just trying to get parts/header.tpl to change to parts/Bathroomheader.tpl or parts/Kitchenheader.tpl based on the vf_category pulled from the database. But it's driving me nuts.
Thanks in advance,
Gary
there are a few ways to do this, but in order to minimize the number of files you're changing, I suggest that you:
a) Pull the variable from the database and assign it to smarty, on your first php file, for both the header and body:
//Assuming you have retrieved $vf_category from your database;
$template_header->setVariable('vf_category', $vf_category);
$template_body->setVariable('vf_category', $vf_category);
b) Edit your file header.tpl and append the following code at the top:
{if 'vf_category' == 'some_value'}
{include file="parts/Kitchenheader.tpl"};
{elseif 'vf_category' == 'other_value'}
{include file="parts/Bathroomheader.tpl"};
{else}
//the rest of the header.tpl code goes here
{/if}
below is the markup im pulling from my database table. basically i want to replace the image
<img src="http://newvision.co.ug/IM/logo_white_big.gif" width="80" style="background-color:white;padding:1px">
to
<div style='background:url(http://newvision.co.ug/IM/logo_white_big.gif) center center no-repeat;width:40px;height:40px'></div>
I dnt wanna use regular expressions just an htmlparser that ships with php

There is no parser that ships with PHP, so use PHPQuery, a way of manipulating the DOM in a JQuery like manner instead. This will allow you to use selectors to easily swap out chunks of HTML.
