PHP - Problem With Repeating Echos

How come my$_SERVER['PHP_SELF'] echos the filename.php

I have a rewrite rule and i need it to echo

http://site.com/file/321

instead of filename.php?id=321


Help! Godaddy wont tell me why its doing that

Hey guys it's been a long time, but I am back with php!

Anyway here's my dilemma:

test.php

<?php
<?php
$name = array('Chris', 'Bob', 'Jack');

$names = print_r($name);
?>


Simple enough right? Well although I am not printing/echoing these results to screen it does it automatically.

Meaning when I point my browser to test.php it outputs this:
Code: [Select]
Array ( [0] => Chris [1] => Bob [2] => Jack )
Rather than only assigning the value to the $names variable, which is what I would expect it to do. Is this normal behaviour or is there something I can change on php.ini?

Thank you!

Hi, all... have a basic question here as a newbie that I am...

Many times, in some scripts I see (I think, if not mistaken), places where within a echo sentence I see variables echoed like this with no quotes:

echo "First Name: $firstName and Last Name: $lastName"; 
as opposed to like one would expect:
echo "First Name: " . $firstName . " and Last Name: " . $lastName"; 

Sometimes I see that also when variables are used in select/update statements I think.. like this:
$query = mysql_query("SELECT FROM table WHERE column = $columnname");
Instead of like this within quotes:
$query = mysql_query("SELECT FROM table WHERE column = '$columnname'");


Is it because some of these values may be numbers (numeric) as opposed to "strings"??
Not sure if I make sense... appreciate teh feedback,
Thanks!

When I log in to my website I am getting something like this in the URL...
Code: [Select]
http://local.debbie///////////articles/article.php?slug=postage-meters-can-save-you-money

If I then navigate to other pages everything seems fine and I get a normal URL like this...
Code: [Select]
http://local.debbie/articles/consider-becoming-an-s-corporation
What is going on?!

can someone help to add new products and increase the quantity of the product when pressing the + button, but it works for [-]

$getmore =  mysql_query("SELECT * FROM block WHERE sid='$idz' ORDER BY `id` DESC",$this->connect);
while ($row2 = mysql_fetch_assoc($getmore)) {

}

}

you see i'm using the result from the first query in the where clause of the second query.  This isn't good practice as what i'm trying to accomplish could lead me doing this up to ten times.  what would be a better way to do this than while loops inside of while loops?


example?

I don't even really know how to title it. I have this piece of code, i wrote. it works with wordpress api but honestly i don't think that matters much.
what it does, is pick $ci number of categories, and then picks 2 posts from each category. it then assigns the image in/attached to that post to an array, to be used later.

this all works fine, the problem is when it picks a post that doesn't have an image. right now, it can't tell that. writing in a bit to be able to tell whether there is an image or not should be easy. i'm thinking it can be as basic as file_exists or as complicated as parsing the post. the part i have the problem with - is how do i make it go back and pick another post/category when it comes up short? more than once? i want it to keep going back until it comes up with an image.

i'd rather not expand the search any farther than necessary

Code: [Select]
<?php
if ( false === ( $scroller = get_transient( $stransient ) ) ) {
if (!is_array($scroller) || count($scroller)==0) {
$args = array( 'type' => 'post', 'parent' => 18, 'exclude' => 63, 149, 278, 62 );
$companies = get_categories( $args );
while (count($companies) > $ci){unset($companies[array_rand($companies)]);}
shuffle($companies);$truckco= array();
foreach ($companies as $company){
$argus = array('numberposts' => 2, 'orderby' => 'rand', 'post_type' => 'post', 'category' => $company->cat_ID );
$listings = get_posts($argus);
foreach($listings as $tn=>$post) {
$truckco[$company->slug]['truck_'. $tn]['image'] = get_the_image( array( 'image_scan' => true, 'format' => 'array', 'width' => '172', 'height' => '129' ) );
$truckco[$company->slug]['truck_'. $tn]['pid'] = $post->ID;
}
}
?>

Hi guys i am a complete novice learning.

I want to automatically load a form page without using the submit button.

i can get the page to load no problems but the url keeps refreshing in the browser window ? here is the code i am using.

 

<h3>View Mileage.</h3>

		
		<form method="post" action="testmileage.php" name="mileage" id = "mileage">

		
		<input type="hidden" name="start-date" value="2020-04-06">

		
		<input type="hidden" name="end-date" value="2021-04-05">

		
		</form>


<script>window.onload = function(){
  document.mileage.submit();
};</script>

 

The code works but the title is repeated with each new set of data. I want the titles set up at the top and never repeating... No idea what is causing it.

$conn = new mysqli($servername, $username, $password, $dbname);
$sql = "SELECT deadchar, level, class, killforumid, realm, date FROM pkdata ORDER BY deadchar DESC";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
    
    
$deadchar = $row['deadchar'];
$level = $row['level'];
$class = $row['class'];
$killforumid = $row['killforumid'];
$realm = $row['realm'];
$date = $row['date'];

$conn->close();

    echo
        "<table><center><tr>
        
            <th>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            
           <font size=3 color=#070719>Victim</font>
            
           &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</th>

            <font size=3 color=#070719>Level</font>
            
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</th>
            <th>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            
           <font size=3 color=#070719>Class</font>
            
           &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</th>
            <th>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            
           <font size=3 color=#070719>Killer</font>
            
           &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</th>
            <th>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
            
           <font size=3 color=#070719>Realm</font>
            
            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</th>
            <th>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

            &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</th>
            
            </tr></center>";




        echo
            "<tr><center>
            
            <td><center>$deadchar</center></td>
            <td><center>$level</center></td>
            <td><center>$class</center></td>
            <td><center>$killforumid</center></td>            
            <td><center>$realm</center></td>

Hey,

I'm not that familiar with PHP so maybe what I'm asking for is not even possible. I plan to establish a webserver that is connected to a RS232 device. I don't have any problems accessing  the RS232 interface with a PHP-script, it's all working fine.

Now I want the incoming data from the device being display on the servers webpage almost in realtime. When I say almost I mean that the client who is logged on to the website should be able to define the update rate of the incoming data.

So here comes the problem, I need something like the java script setinterval() function that is working on the server-side and repeats the data request to the device in an infinite loop with the given time interval.
I don't want to refresh the whole page as I will have to update about 20 sets of data within seconds!

I found this code:
http://phpclasses.chimit.nl/package/5544-PHP-Call-a-function-after-a-period-of-time.html
it looks pretty promissing but I just can't make it working...

As I said I'm a PHP-noob so I just put the code below on the start of my own code and provided the Timer.class.php file in my project folder. Could anyone explain how I could make the test function repeating endlessly on a 1sec basis using this code so I would get a screen full of "called"? So far I only get two "called" :-)

Thanks!


declare(ticks=100);
function test ()
{
    print "<br>called";
}
require_once 'Timers.class.php';
setTimeout('test', 110000000);
setInterval('test', 10000000);

I know I am probably complicating this but I am looking for a way to code a header and footer to the exterme top and extreme bottom of my pages. I have seen it before but I have no idea how to do it from scratch. But I ore or less want to be able to edit my header or footer one time and it work every where.

Thanks in advance.

I have a simple problem but seem to be hitting a roadblock with fixing it.

I am in the process of upgrading a site from PHP 5.6 to 7.0 (eventually to 7.2)

I am seeing error notices like

PHP Notice:  Undefined index: productpage in …..

I know this it because the $_REQUEST can sometimes be empty depending on what data is passed back and when certain pages are loaded

$productpage = mysqli_real_escape_string($con, $_REQUEST['productpage']);

I also know that I could turn the error notice off or use isset to check $_REQUEST but I would prefer to use the ?? '' option to fix this issue.

The problem is that when I add the ?? '' option to the above code the problem resolved itself but then moments later the same error on the same line reappeared in the error logs and I cant understand why.

Can someone give me the correct example of where to place ?? '' in the above code so that I can rule out my potentially dodgy code as being the reason the error keeps reappearing.

sorry if i have posted this in the wrong place, wasnt sure wether to post here or mysql.

I have made a php calendar, and i am now wanting it to show if there is an event on that day and if so show it in a tool tip. the tool tip is populated by what is in the title="" of the link so i need my events to be shown in there. I have figured out how to show the event but now i am stuck on how to show all events if there is more than one one that day, how i have set it seems to only the second event, probably as the second variable overwrote the first variable.

this is the code i have at the minute ..............

$result = mysql_query("SELECT * FROM events WHERE day='$day_num' AND month='$fullmonth' AND year='$year'") or die(mysql_error());

$rows= mysql_num_rows($result);
if ($rows !="false"){
while($rowout = mysql_fetch_array($result)) {
$todayis = $rowout['day'] ."-". $rowout['month'] ."-". $rowout['year'] ."<br>";
$title= $rowout['event'] ."<br><br>";}
$firstl = "<a href='' title='". $todayis . $title ."'>";
$lastl = "</a>";}
else {$firstl = ""; $lastl = "";}


then to display the day and links .................

Code: [Select]
<td><? echo $firstl; ?><? print $day_num; ?><? echo $lastl; ?></td>

could some one be so kind and help me write it so that it displays all events?

here is a link to the calendar, incase its needed. http://www.scripttesting.htmlstig.com/calendar/index.php

Many thanks

Hello Everyone,

I'm using PHP with MySQL.  One of the fields in the database is website.  The code I'm using is as follows:

variable:

$web=mysql_result($result,$i,"web");

html/php code:

<td><font face="Arial, Helvetica, sans-serif"><a href="<? echo "$web"; ?>">Website</a></font></td>

What it should do is have the clickable word Website with the correct url from the database.  Instead it's repeating the website the page is on.  For example it's doing this:

http://mywebsite/www.enteredwebsite.com

Any help is appreciated.
