PHP - Print_r() And Array_sum()

Here's the result of my problem:
Array ( [nav_create_title] => hel [nav_visible] => 1 [category_position] => 4 )
( ! ) Notice: Undefined index: category_postion in C:\wamp\www\tryitandbuyit\includes\category_create_process.php on line 7
Call Stack
#   Time   Memory   Function   Location
1   0.0010   370336   {main}( )   ..\category_create_process.php:0

Here's how I'm trying to assign and echo $_post.
print_r($_POST);
$category_pos = $_POST["category_postion"];
$nav_title=$_POST["nav_create_title"];
$nav_visible=$_POST["nav_visible"];



echo $nav_title;
echo $category_pos;
echo $nav_visible;


As you can see, it prints the correct value and name from the array... why the heck can't I assign or echo it?

Here is how I am sending it from the other page in a form (it used to be simple, but I've been trying every work around i can think of:
<?php
$result=mysql_query("SELECT * FROM category WHERE visible='1' ORDER BY position ASC");
$row=mysql_fetch_array($result);
$positionID=$row['position'];
$position=$row['position'];
$selectname= "Select A Position:<br />";
$selectname .= "<select name=";
$selectname .= "'category_position'";
$selectname .= ">";
echo $selectname;
$rownumber=mysql_num_rows($result);
$rownumber_temp=$rownumber+1;
For($i=1; $i<=$rownumber_temp; $i++)
{
echo "<option value= $i>" . $i . "</option></br>";

}
$selectname2 = "echo \"<br />\"";
$selectname2 .= "echo \"<br />\"";
$selectname2 .= "echo \"</select>";
echo $selectname2;

I am working on modifying some code and wanted to check some variables, but am stuck on something that is probably simple, just over my head.  If I do the following:

print_r ($this);

I get this result (I used PRE tags to format it)

ViewList Object
(
    [_name] => list
    [_models] => Array
        (
            => ModelList Object
                (
                    [_data] => Array
                        (
                            => stdClass Object
                                (
                                    [id] => 70
                                    [catid] => 1
                                    etc......

Moving down, I typed this...

print_r ($this->_models);

and get this...

Array
(
    => ModelList Object
        (
            [_data] => Array
                (
                    => stdClass Object
                        (
                            [id] => 70
                            [catid] => 1

How would I get, for instance, the id?  If I try print_r($this->_models->list);  nothing happens.  In other words, if I wanted to return the id, what would it be --  $this->_models->??? .  I tried all kinds of combination's and other ways to do it, just can't figure it out.  I know it is my limited knowledge with PHP , so could someone point me in the right direction.

Thanks,

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.

Hey


Is there a way to trim the print_r($array); so its completed and void of white space?


It prints like this:



Code: [Select]

Array
(
    [0] => Array
        (
            [id] => 10
            [f] => data/tiles/image.png
        )
)

But I want it to be compressed like this:


Code: [Select]
Array([0]=>Array([id]=>10[f]=>data/tiles/image.png))
This is then to be stored in the database, so any compressed possible is a plus in this situation.


Any ideas?

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!

i have checkboxes on the database page and if checked they send to the shopping basket i have the items selected to display but like this  Array ( [0] => Imagine DragonsImagine DragonsRockI Bet My LifeKIDinaKORNER1.25Brand new single from the incredible Imagine Dragons )  

So I have been printing out some debug information, and now I am trying to instead save it to a string, which I will print out at the end of the page. Here is some specific problematic code:

$myplugin_debug_test.= "\n[GETTING COOKIES...\n";
$myplugin_debug_test.= print_r($myplugin_all_cookies);//THIS IS LINE 38
$myplugin_debug_test.= "\n... DONE]<br/>\n";

However, when I do this I get the following error:

Quote

Warning: Cannot modify header information - headers already sent by (output started at ...:38


So my question is how can I output the array data into a string, so that I can print it out later.
Like what am I doing wrong? Is there a better way to do this?

Thanks!

I am making a price sheet for extended warranties that my company sells and am having a problem with the math.
There is a base price of $1380, plus certain surcharges and certain exclusions. The exclusions are working properly, but something funky is happening with the surcharges...

This link more clearly explains the problem I am having:
http://www.carcityofdanbury.com/New/01/Resources/printable_list_Admin.php

Here is the code, then I'll explain the problem
Code: [Select]
// TMU
if ($row['TMU'] == "x") {
$extended = 'N/A';

// Salvage Title
} elseif ($row['cleantitle'] != "x") {
$extended = 'N/A';

// 150,000+ miles
} elseif ($row['mileage'] > "150000") {
$extended = 'N/A';

// Snowplow
} elseif ($row['ftr003'] == "x") {
$extended = 'N/A';

// Category 3
} elseif ($row['make'] == "Jaguar" || $row['make'] == "Land Rover") {
$extended = 'N/A';

// 10+ cyls
} elseif ($row['engine_cylinders'] > "8") {
$extended = 'N/A';

// Older than 13 years
} elseif ($year < date("Y")-12) {
$extended = 'N/A';

// Qualifies for warranty
} else {

if ($row['mileage'] > "99999" && $row['mileage'] < "125000") {$surcharge[] = 200;}
if ($row['mileage'] > "125000" && $row['mileage'] < "150001") {$surcharge[] = 400;}
if ($row['drivetrain'] == "AWD" || $row['drivetrain'] == "4x4") {$surcharge[] = 150;}
if ($row['fuel'] == "Diesel") {$surcharge[] = 100;}
if ($row['make'] == "Audi" || $row['make'] == "BMW" || $row['make'] == "Cadillac" || $row['make'] == "Infiniti" || $row['make'] == "Lexus" || $row['make'] == "Lincoln" || $row['make'] == "Mercedes-Benz" || $row['make'] == "Mini" || $row['make'] == "Saab" || $row['make'] == "Volvo") {$surcharge[] = 550;}
if (date("Y")-11 == $year) {$surcharge[] = 50;}
if (date("Y")-12 == $year) {$surcharge[] = 100;}
if (date("Y")-13 == $year) {$surcharge[] = 200;}

if ($surcharge) {$surcharges = array_sum($surcharge);}
$extended = '$'.number_format(1380 + $surcharges);

}

The 9th vehicle on the list: 08 Hyundai Sante Fe SE the warranty price is correct, but the vehicle after, the 08 Honda Accord EX should be 1,380, yet its adding the surcharges from the the Hyundai, and it keeps repeating down the list.

Where is the error?

the array is getting the values as he should get and from there i send them to $temp (string),but when i'm trying to print them i can't.

the array and the string at the end of code saved the values that the code gave them,but i can print the values one by one, but i need the values in string and the array at the end and print $temp(string) in a row without white space. print_r is working but she's not build to this job 

can someone look at the code and the result of the code and tell me what seem to be the problem and how to fix that?
the problem start with $txt when the array is getting the values.
the output of this code:http://pastebin.com/0QkzjviW
the code page is attach to this message as php file.
