PHP - Determine If The First Character Is A 0

This may sound funny, but I'm not sure what I was trying to get this code to do...
Code: [Select]
        <!-- Find Current Page Name -->
        <?php
          $page = basename($_SERVER['REQUEST_URI']);
echo '<p>$page = ' . $page . '</p>';
//          if ($page == '') {
          if (($page == '/')||($page == '')||($page == 'index.php')){
            $page = "index.php";
echo '<p>You are on the Home Page.</p>';
          }else{
echo '<p>You are on Some Other Page.</p>';
}

What I mean by that is I'm not understanding why I chose...
Code: [Select]
          if ($page == '') {

and then...
Code: [Select]
          if (($page == '/')||($page == '')){

and then...
Code: [Select]
          if (($page == '/')||($page == '')||($page == 'index.php')){


Why would I get those different results from basename($_SERVER['REQUEST_URI'])??

And what should I expect locally on my Laptop with a Virtual Host set up (e.g. "http://local.debbie/index.php") versus using a Test Site (e.g. "http://www.doubledee.byethost2.com/") versus a real site (e.g. "www.debbie.com")?!

Hope I'm making some sense here...

Hi, I'm making an attempt to build a small cms based site. I have read in a lot of places it is best to use the id of a table row to fetch contents, but being as I am using url rewrite in frontend, it won't be showing query strings, so I thought I would ask if anyone saw any potential problems if I did the following.

Page table looks like this:
Pages
- id
- name
- content

In backend, the user has a form to name the page and use ckeditor to add rich content. I will use php to ensure that the name is alphanumeric and use strtolower & str_replace to ensure that My First HTML Page is sent to mysql as my-first-html-page and also check that a row with this name does not already exist.
So on front end this page url will be mywebsite.com/my-first-html-page

So to output the content I strip out the domain & / so I'm left with the name as entered in the db.

$url = $_SERVER['REQUEST_URI'];
$url = str_replace ('/','',$url);

Then in my function to output content I will use WHERE name = $url

Hi,

Competitors vs. against each other and are recorded in a database. Each participant equally has 4 matches each, as you can see in the attatchment following the points gained in their played matches. I want to be able to determine the qualified participants according to either their "points" or "wins/losses". If two competitors have the same points, then I have already made a solution that another match must be generated for the two participants with the same points and draws can not be submitted which means the points will always be different for each team.

I want to pick out half of participants 8/16 (screenshot below) with highest points which will be the qualifiers, or pick out half participants 8/16 with best match stats according to wins/losses.

Any help I would be very grateful, thanks.

How to reliably determine if server is Apache using PHP?

For example isApache() function?

I have this function, but it doesnt work. Basically the list outputs a list of news features, and puts a line under neath each article to seperate them. However once the last article has been reached, I don't want the break to be shown.

this is my code, any help would be appreciated as i am really struggling on this. Just need to determine the last item in the array, and stop the <hr split> from being output.
function newsFeature(){
$event = "SELECT imgname, title, content, pkID from news ORDER BY date, time DESC LIMIT 5";
$event_page = query($event);
$count = numRows($event_page);

while ($row = mysql_fetch_assoc($event_page))
{
$rowcount = $count;
$para = substr($row['content'] , 0,100);
$result .= '<article>';
$result .= '<a href="news-article.php?pkID=' . $row['pkID'] . '"><img src="uploads/thumbs/' . $row['imgname'] . '" alt="" width=116 height=83/ ></a>';
$result .= '<h2><a href="news-article.php?pkID=' . $row['pkID'] . '">' . $row['title'] . '</a></h2>';
$result .= '<p>' . $para . '...</p>';
$result .= '<p><a class="read-more" href="news-article.php?pkID=' . $row['pkID'] . '">Read more<span></span></a></p>';
$result .= '</article>';
if($row != end($row[])){
$result .= '<hr class="split">';
}
}
return $result;
}

When I upload new files, their file name is stored into my database. I have been told that a couple of the file downloads weren't working. Upon further investigation I figured out that the file the person wanted to download was nowhere to be seen in my downloads directory. How can I determine if a file exists in my directory? I assume I can somehow use the location that is stored inside my database (ex: myfile.pdf) and compare that with what's in the folder.

I can determine which radio button is selected for each file upload prompt because I have a name and a value. So the array name=image can have one of three values for each file upload prompt.

Is there a way to determine which of the three file upload prompts was loaded (clicking browse & select image) with an image and which was not? There doesn't seem to be a value like there is with radio buttons. I want to be able to replace an already uploaded image with another.

Thanks.

<input type='radio' name='image[image0]' value='keep' checked='checked'/>
<input type='radio' name='image[image0]' value='delete' />
<input type='radio' name='image[image0]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image1]' value='keep' checked='checked'/>
<input type='radio' name='image[image1]' value='delete' />
<input type='radio' name='image[image1]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image2]' value='keep' checked='checked'/>
<input type='radio' name='image[image2]' value='delete' />
<input type='radio' name='image[image2]' value='replace' />
<input type="file" name="image[]" />

if (isset($_POST['submitted']) && 
($image = $_POST['image'])) {

foreach($image as $imageKey => $imageValue) {
if ($imageValue == 'keep') {
do this
}
}
}

When will modern PHP copy an array by reference only instead of reassigning to memory?

For instance, when I execute $bigArray=$stmt->execute([$id]), PHP utilizes memory to store the data.  But then when I execute $dataHolders[] = new DataHolder($bigArray), I believe $bigArray is passed by reference and a new copy of $bigArray will not be stored in memory.  If in DataHolder::__construct, I executed $data[]='bla', then it is my understanding that PHP would see that the array is being modified and will automatically make a copy, but I am not doing so and just state this to confirm my understanding.

The part that I am uncertain about is not the first time data is retrieved but any additional times.  When I execute the next $bigArray=$stmt->execute([$id]), will PHP need to first store in memory the array that DataHolder::data references, then release the memory associated with $bigArray, and then store in memory the new $bigArray?

 

<?php

class DataHolder
{
    private $data;
    public function __construct(array $data)
    {
        $this->data=$data;
        //$this->data[]='bla';   <--  I believe this will force PHP to make a new copy of the array but I am not doing so
    }
}

$dataHolders=[];
foreach($ids as $id) {
    $bigArray=$stmt->execute([$id]);
    $dataHolders[] = new DataHolder($bigArray);
}

 

I would like my website to show which users are logged in.
Is there a simple way of retrieving all session ids from the server that have been allocated and are active in order to do this?
I know this could lead to faulty information, but would appear to be the simplest and reliable.
Thanks.

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.

Not asking you to troubleshoot for me but to pop in any thoughts you might have on how YOU would troubleshoot this problem.. Thanks

This is a wp site.. and generated the following error..
 

Notice: Undefined index: USER_AGENT in /home/luxuryrealtygrp/public_html/wp-content/plugins/LRG/Masked/Filters.php on line 31

This is what line 31 that is being called out:
Line 31:
function lrg_masked_field($false, $field_name){
    if(is_user_logged_in() || stripos($_SERVER['USER_AGENT'], 'google') !== false || stripos($_SERVER['USER_AGENT'], 'yahoo') !== false || stripos($_SERVER['USER_AGENT'], 'bing') !== false){
        return false;
    }

Just looking for ideas that might help to chase this down..
My guess is that USER_AGENT since in all caps may be an environment variable.. Is there a way to display all environment variablles and if they are set or not.  Any ideas or thoughts would be appreciated.. Thanks!

Hi,

I want to add another form field to determine if a user is human and not spam bots. I looked into CAPTCHA, but I think those are annoying. I was thinking about just having the user enter (5+5) and if the answer is not ten, then displaying a incorrect value message. If correct submit form and info to the Database. Not sure how to do that with what I currently have coded though so need some help with that part. Here is the current code.


<?PHP

Hi, I need to add a function for a date field on a form being submitted to MySQL DB. Something similar to this for a website field, except it shoudl make sure the format is in 01/05/2010 or 2numbers/2 numbers/4 numbers format...


if(!mb_eregi("^[a-zA-Z0-9-#_.+!*'(),/&:;=?@]*$", $website))
$this->setError('website', 'invalid website');
elseif(mb_strlen(trim($website)) > 120)
$this->setError('website', 'too long! 120 characters');


thanks in advance for any assistance.

I have a page using forms to help build listing templates for eBay. I have a folder where I have hundreds of logos stored. I know the logo names but not their extensions. . . . I have to test each potential (jpg, jpeg, gif, png, etc.) until I guess right. Here is an example code for the web form: <form action="extension_test2.php" method="post">
<p>Logo: <input name="e" value="" type="text" size="15" maxlength="30" /><p>
<input name="Submit" type="Submit"/>
</form>   and the form's result: <?

$e =$_POST['e'];

if(!empty($e)) {
echo '<img src="http://www.gbamedica...ebayimg/logos/'.$e.'">';
};

?>   Here is a link to the example: http://www.gbamedica...ension_test.php Use "olympus.jpg" for test. I am looking for code that can determine the file type and dynamically add the extension. Can it be done?

I know via firebug that the correct parameters were passed to my process page and the parameter being passed that in caused issues on the process page is $characterIDList. What's causing the issue is that its not inserting the value into the insert query. The rest of the insert query works fine.

process page


$characterIDs = explode(',', $_POST['characterIDList']); 
    foreach($characterIDs as $itm){
         $id = (int)$itm;
     }
    $defaultcharid = (int)$characterIDs[0];

$query = "INSERT INTO `handlers` (username, password, firstname, lastname, email, status_id, isadmin, default_character_id, creator_id, datecreated) VALUES ('$username','$password','$firstname','$lastname','$email','$status','$admin', '$defaultcharid', 1, NOW())";
