PHP - Includes Changed By $_variable

After switching from PHP 5.3 on Windows Server 2003 to PHP 7.4.3 on Linux Mint 19.3 (Tricia Cinnamon), I find that the output of print_r() has changed.

If we look at the documentation (https://www.php.net/manual/en/function.print-r.php), the provided example output is as it was on my earlier machine:

<pre>
Array
(
    [a] => apple
    [b] => banana
    [c] => Array
        (
            [0] => x
            [1] => y
            [2] => z
        )
)
</pre>

However, on the second machine, the output is:

<pre>
Array
(
    [a] => apple
    [b] => banana
    [c] => Array
        (
            [0] => x
            [1] => y
            [2] => z
        )
<blank line>
)
</pre>

Note the unexpected new line after each recursed array's closing parenthesis. The new line is not present after the outermost array closing parenthesis.

Also to note, there is a newer version of XDebug installed.

My question is: Is this a bug? (Follow-on question: if possible to determine at which version the output changed, what version would that be?)

This difference is causing existing code to not be able to correctly parse that output.

I have no idea if this is possible or not, but I've got a form that searches a DB for a record.

If that record is found, it displays a form that people can edit the record.

Now, if that person wants to change (for example) 1 record out of 16 called "status" from "lost" to "found" but leave all the rest as they are, how would I go about this?

Basically, I need to check all the fields ON SUBMIT if they're different from the original values in the DB and only update if they are.

Any help would be appreciated.

Cheers,

Dave

Hey Guys,   I'm doing some coding and I've managed to snip something off....   This is the original code

<form method="post" action="{$systemsslurl}cart.php?a=add&domain=register">

<table class="table table-striped table-framed">
    <thead>
        <tr>
            <th></th>
            <th>{$LANG.domainname}</th>
            <th class="textcenter">{$LANG.domainstatus}</th>
            <th class="textcenter">{$LANG.domainmoreinfo}</th>
        </tr>
    </thead>
    <tbody>
{foreach from=$availabilityresults key=num item=result}
        <tr>
            <td class="textcenter">{if $result.status eq "available"}<input type="checkbox" name="domains[]" value="{$result.domain}" {if $num eq "0" && $available}checked {/if}/><input type="hidden" name="domainsregperiod[{$result.domain}]" value="{$result.period}" />{else}X{/if}</td>
            <td>{$result.domain}</td>
            <td class="textcenter {if $result.status eq "available"}domcheckersuccess{else}domcheckererror{/if}">{if $result.status eq "available"}{$LANG.domainavailable}{else}{$LANG.domainunavailable}{/if}</td>
            <td class="textcenter">{if $result.status eq "unavailable"}<a href="http://{$result.domain}" target="_blank">WWW</a> <a href="#" onclick="popupWindow('whois.php?domain={$result.domain}','whois',650,420);return false">WHOIS</a>{else}<select name="domainsregperiod[{$result.domain}]">{foreach key=period item=regoption from=$result.regoptions}<option value="{$period}">{$period} {$LANG.orderyears} @ {$regoption.register}</option>{/foreach}</select>{/if}</td>
        </tr>
{/foreach}
</table>

<p align="center"><input type="submit" value="{$LANG.ordernowbutton} &raquo;" class="btn btn-danger" /></p>

</form>

and I've changed it to:

 <form method="post" action="{$systemsslurl}cart.php?a=add&domain=register">
    {foreach from=$availabilityresults key=num item=result}
    
        {if $result.status eq "available"}

            <input type="submit" value="{$LANG.ordernowbutton} &raquo;" class="btn btn-danger" /></div>
           
            
        {/if}
        
        {if $result.status eq "unavailable"}
            <div style="width: 400px; color: #cc0000; font-size:14px;"><img src="/templates/dj/no.jpg" style="float:left" />{$tld}<br />Taken</div>

        {/if}
    
    {/foreach}</form>

The original code works fine and add to my cart, the new "updated" version fails...   What have I done wrong?

I have just upgraded PHP on my ISP server and none of the php scripts work.
I was using 5.2. And I am now on 5.4.
Why would the scripts stop working?
Are there and patches or changes I need to make to make them work?
I need an answer urgently!

I have 3 set of pages. The first html page only contains a search textbox and a submit button which then call up the second page search.php which populate html table with search result. The third page is update.php which allows to update the records populated by search.php.

The problem is that it when it update the records it automatically updates all rows in the table making all records look the same. I do not know where I have made a mistake please help. When I use phpadmin to update the records no problem as I can specifically input the cf_id number directly.

Thank you in advance for your help

I'm trying to get some code to work that will update a field to show a checkbox either checked or not checked.   The field either uses a Y or N.  Y is checked, N not checked.  A code that I have tried displays the correct result for the box either checked or not checked. 

input type="checkbox" name="obcDisplay" value="Y" <?=($r['obcDisplay'] == 'Y') ? 'checked="checked"' : ''; ?>/>

But I want the ability to change when the form is submitted.  so if I bring up a page and the checkbox is checked (Y) and I submint, I want the database to update to N and the other way around.

Hey all,

I would like to know the best way to determine whether a value has been changed in a multi select transfer. For example, I have two select fields. User clicks on button to add an item to the right select element with id of select2 from the left select element with an id of select1. When they click update, it posts to a php method. This is where I am uncertain what to do. How can I check that they indeed added or removed items from the right select element and if they did, determine which ones were removed or added to make the reflected changes in the database?

This is what I have, but it's bad solution because it deletes all related records before it adds the ones it finds to the right select element:

Code: [Select]
public function update(){

$subcategory = new Category();
$subcategory->where('id',$this->uri->segment(4))->get();

$subcategory->delete($subcategory->related_category->get()->all);

$new_parents = $this->input->post('catupload');
$parent_category = new Category();
$parent_category->where_in('controller',$new_parents)->get();

$subcategory->save($parent_category->all);
}


This is what the form elements look like:

Code: [Select]
echo "You can add or remove one or many parents associated with this category:";
echo "<div class='multiselect-transfer'>";
echo form_multiselect('catadd[]',$other_cats,'','id="select1"');
echo anchor('#','add &gt;&gt;','id="add"');
echo "</div>";
echo "<div class='multiselect-transfer'>";
echo form_multiselect('catupload[]',$default_cats,'','id="select2"');
echo anchor('#','&lt;&lt; remove','id="remove"');
echo "</div>";
echo form_submit('submit','Update');
echo form_close();
$other_cats variable holds array of categories that have not been asssociated with the current category being updated when this category was first created. The $default_cats variable holds an array of categories that have been associated with the current category being updated when this category was first created.

And the javascript:

Code: [Select]

 $().ready(function() { 
   $('#add').click(function() { 
    return !$('#select1 option:selected').remove().appendTo('#select2'); 
   }); 
   $('#remove').click(function() { 
    return !$('#select2 option:selected').remove().appendTo('#select1'); 
   }); 
  });

Thanks for response.

Hello,
I'm using curl to grab a new solar image once an hour or so from the Solar Dynamics Observatory (example below). I'm trying to archive new images and am struggling with that.

If I download an image, the filetime() function returns the current time since I downloaded it and wrote it to a fresh file. The result is that the file is always "new", even if the image hasn't changed on the SDO website. Do you have an idea on how to check the last modified time of a file through curl or other means so that I'm not downloading duplicate images?

Thanks a ton!



//fetch image
$ch = curl_init("http://www.somewebsite.com/theimage.jpg");
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
$file = "../images/latest/theimage.jpg";
$fp = fopen($file, "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);

//this part is no good...
//get last modified date
if (file_exists($file)) {
$filetime = filemtime($file);
}

Hi all,
I created a page template at http://www.durgeshsound.com/gallery/
Here my pagination buttons are not working. this issue arises when permalink format is http://www.example.com/sample-post/
But when I set permalink format to default (www.example.com/?p=123) then it starts to work
and creates a working pagination link like this http://www.durgeshso...e_id=81&paged=2.  I want this format http://www.example.com/sample-post/ in the links.
Please help.

Sorry for the long message but I need HELP!!!  I'm somewhat familiar with HTML but very little in PHP, and even less in CSS. My eCommerce program is PHP based so I've had to learn to work with it. I did have someone else initially setup and create my website but over the past few years have taken it further myself. I've fiddled with some of it and looked up how to do certain things, such as have only one header and/or sidebar I can use for all pages. I use Dreamweaver CS4 and FTP with FileZilla. But I'm still new at this and have run into a couple of issues.   My webhost is GoDaddy, my website is MikiCat Designs and after fiddling for months, in March finally got my site to where I liked it. Unfortunately, I haven't kept it up. Anyway, I went there a couple of weeks ago and found that the PHP includes I'd had in the HTML files were no longer working. I get the error [an error occurred while processing this directive]. Weird. Worked fine before, now it doesn't. Called GoDaddy who says they didn't do anything . Uh huh. Now I know I didn't do anything since I haven't updated the site in 4 months! So, what could have caused this problem?

I've had no idea how to fix it other than to change the index.html to index.php and, of course, do a minor repair on the include. Works fine and my header.php and leftsidebar.php show up again. Yay! Herein lies another problem.

My header and sidebar link to other files some of which were HTML files. But those HTML files had the same header and sidebar issues as my INDEX file. This had to be fixed so I changed them to PHP. Still working on the changes. I deleted most of the HTML files from the server.

So the links in my header and lefsidebar files now point to PHP files. e.g., gallery.html to gallery.php. When called on it's own, gallery.php shows up perfectly. But, no matter what I do, the header file still tries to load the HTML file!!! It's driving me crazy. What have I done wrong? I've deleted them both, refreshed, cleared cache and uploaded them again but I still get the same error. If you click on Gallery in the header, it tries to link gallery.html not gallery.php! Funny thing is, the leftsidebar now works perfectly and points to the proper PHP files. I'm completely confused now.

I don't know why my header is insisting on trying to load the HTML page instead of the PHP. But here's my header code. Lines 41 and 42 work, lines 43, 44 and 45 do not.   * Quietly banging head against wall while awaiting help.

Hi all

My site is build using php includes. the index.php file contains code like
<?php
if(@$_GET['page'] == "web-design"){
   include("includes/web-design.php");
} else if(@$_GET['page'] == "hosting"){
   include("includes/hosting.php");   
}
 else {
    include("includes/home.php");
 }
?>

I have created a sub domain blog.maplewebdesign.co.uk and a sub dircetory named blog. The link to this part of my site doesn't use includes, I want it to link directly to that sub directories index.php page.
This works fine, but then when I click on a different link anywhere on the site my url is as follows
www.maplewebdesign.co.uk/blog/index.php?page=home

For some reason it is keeping the blog/ in the URL

If you want to see go to
http://www.maplewebdesign.co.uk/blog/
then click on a differnt link and check out the URL

What am I doing wrong?

Thanks
Adi

If one file includes another, do I need to start a session in each, or does the included file "inherit" the session?

script_1.php

// Initialize Session.
session_start();

// Require Function
require_once('script_2.php');



script_2.php

// Initialize Session.
session_start(); DO I NEED THIS HERE?????????

if ($_SESSION['loggedIn'] == TRUE){
do something
}

Hi,

Im pretty much self taught when it comes to php, never read any books just picked things up as i go, and im looking for some advice on how i build my pages as i believe im not approaching it correctly.

Basically i build an index.php, this contains my header, footer, and any menus i may have, then for my content pages, in this case products, contact, about us i use use an include so these content pages just have content.

Now by doing this my address bar looks like this index.php?location=contact.php

for the sake of google and search results and so on, am i limiting my ability to be found by not using a differant file for each page? should i include a header, footer, menu etc within my content pages rather than the other way around?

Thanks in advance for any advice.

Hey everyone,

I am trying to secure php includes and I wrote the following lines:

Code: [Select]
<?php
$dir=scandir('.');

if (in_array('copyright.php',$dir)) {
include('copyright.php');
}
else {
echo 'That page could not be found';
}
?>

Is this code secure enough, can anyone help me improve it?

Thanks in advance.

Ok, I am sure this is really simple for all of you, but I have very little experience with php. I haven't sat down to learn php yet, but I will when I have more free time. In the meantime I have the following issue:

The site is http://astoryaday.fromyay.com/

I have all the stories in the /stories/ directory, all named 20110504.html, 201105005.html, etc. Every day I write another story, I name it following that pattern, and drop it into the /stories/ folder.

I only want the newest story displayed on the page. So I wrote a little script that is:
Code: [Select]
<?php
$files = glob("stories/*.html");
sort($files);
$newest = array_pop($files);
include($newest);
?>
Now, what I want to do, is in the footer, put an Archive that will look like this:

-2012
--January
---03
---02
---01

-2011
--December
---31
---30

And upon clicking on the dates, the story from that day will replace the story that is currently included.

Any help of how to get this done would be appreciated!
Thanks
