PHP - Trimming An Exploding Array

I'm more or less a noob. I have used the below code on another webpage, but on a new site that I am working on I attempted to trim the variable and now the page won't load. Can someone show me what I did wrong or a better way to accomplish this?

Code: [Select]
<?php 

# GRAB THE VARIABLES FROM THE URL
$x = $_GET['x'];
 
$valid = array('cat:1', 'cat:2', 'cat:3', 'cat:4', 'cat:5', 'cat:6', 'cat:7', 'cat:8', 'cat:9', 'cat:10', 'cat:11');

if(in_array($x, $valid))
$trimmed = trim($x, "cat:");
include_once $trimmed . '.inc';

else
  include '1.inc';  

?>

When I used this before my variables did not have a colon in them, so I did not have to trim the variable, thus the last part of the script was:

Code: [Select]
if(in_array($x, $valid))
include_once $x . '.inc';

else
  include('1.inc'); 
?>

I need to explode data separated with text separators, like this:

banana|carrot|salmon|oak|tuna|apple|elm|pineapple

So far so good with this:

<?php
  $items = explode('|', $stuff);
  foreach($items as $key=>$value){
?>


But now I need a list, with categories from another table (column1=items, column2=corresponding categories) and order by categories (not worried about the order of the items under each category), like this:

FISH
   salmon
   tuna
FRUIT
   banana
   apple
   pineapple
TREE
   oak
   elm
VEGETABLE
   carrot

Any suggestions on an approach would be appreciated. I'm foggy about creating arrays, but I think I need one here?

Hello,
I fetch information from an URL, and this is the output I get using cURL (there's no other way I can get it):
Quote

4377.54,11069.02,13.15,3,101,11342,1512492

Now I want to explode this, but I can't directly explode this using explode. How do I do this? Once I use curl_exec it is always displayed.

$characterIDs = explode(',', $_POST['characterIDList']);

After the explode I want to take all those values and do a select statement in a database table for any of the values that match any of the values inside that variable variable. Not sure how to do this since there is no limit to how may there could be.

I am trying to get more than one row from a database at once, then explode each value into a seperate variable. is there a way of doing this?

I have the following code which has deliimiters of |||| and I need to break it apart into three strings and have a variable assigned to each string.

I've tried exploding it but won't dynamically increase the variable.  I know at one point about a year ago I used something like $var.=$foo and the $var would increase $var1, $var2, etc...

Here's the string I need to break.j (And the string will be different every time, and some will have 2 string delimited  some will have 20, and some inbetween.

Hi,

I've been asked to modify a section on a site for a local club.

Basically, I've been asked to improve the name input section (a user may have to input up 15 names in one visit to the site).

At the moment the site works like this:
The user enters one members first name in one form box, then the surname in another, then presses "add name" which adds it to the list.

What i want to be able to do (and i'm sure i've seen it somewhere), is have the user enter the list of names into one big text area: Type in the first name then the surname, hit enter for a new line in the text area then type the next name....etc. When the list is complete press "add names" button.

Is there a name for this type of input? And does it work on the following principle:
1. The entire text sent from the text area can be exploded into an array using the line break as the delimiter
2. Each value in the array is then the first name and second name.
3. I can then explode each value further now using the space as the delimiter.
4. I am left with a bunch of arrays containing the first name in one value and the surname in the second

Any help or pointers here would be class

Cheers,

John

Code: [Select]
<?
$out = preg_replace('/^(.{701}[^.]*).*/i','$1.',$detrsltnewsrow[news_desc]);
echo $out;
?>

</td></tr><tr><td colspan="2" class="para" style="padding-left:10px;">

<?=
substr(stripslashes(trim($detrsltnewsrow[news_desc])),701)
?>
                                             
</td></tr>

I have the above snippet.. The first php statement, basically grasp the first 701 characters with the closet next stop "." character and out puts it. then out puts the HTML tags

I have a problem with the second statement. I want to output anything after what has been outputted by:
Code: [Select]
<?
$out = preg_replace('/^(.{701}[^.]*).*/i','$1.',$detrsltnewsrow[news_desc]);
echo $out;
?>

So need the correct syntax for
Code: [Select]
<?=
substr(stripslashes(trim($detrsltnewsrow[news_desc])),701)
?>
Currently it breaks at exactly the 701 character, want it to continue from the sentence the first code ended in.

hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped.

NOTE - Please read the information first as it contains important information to understand the problem.

Rules →

• There are 9 Columns(C1,C2,C3,C4,C5,C6,C7,C8,C9) [ Max columns will be 9]

• The number of Rows can vary from 3,6,9,12,15,18 (Max). In this case Number of Rows shall be 12

Number of Rows = No of Tickets (Max Allowed 6) x Rows Per Ticket (Max Allowed 3). Thus, Max Rows can be 18

• Each Row is required to have 4 Blank Spaces and 5 Filled with Numbers

• All numbers available in the Column Array have to be utilized

• This configuration of an shall create a matrix of 9 Columns & 12 Rows (3 x 4 Tickets), which is 108 MATRIX BLOCKS where only a maximum of 60 numbers can be filled out of 108 available blocksrandomly with the above conditions being met 100%.

• The numbers in column must be arranged / sorted in ASCENDING ORDER (For coding logic purpose, as soon as the number is assigned to the new MATRIX MAP use array_shift() or unset() the number so as to avoid repetition

Example - Row 1 and Column 1 shall generate a MATRIX BLOCK - R1C1

Row 3 and Column 7 shall generate a MATRIX BLOCK - R3C7

Matrix Block can also be termed as Matrix Cell for your ease (if needed)

MASTER SET OF ARRAY WITH NUMBERS

array( "C1"=> array( 1, 2, 3, 5, 6, 7, 9 ), //7 Numbers "C2"=> array( 13, 14, 15, 17, 18, 19 ), //6 Numbers "C3"=> array( 21, 22, 23, 24, 25, 26, 30 ), //7 Numbers "C4"=> array( 31, 33, 34, 36, 37, 38, 39 ), //7 Numbers "C5"=> array( 41, 42, 46, 47, 48, 49, 50 ), //7 Numbers "C6"=> array( 51, 52, 53, 54, 55, 57, 58 ), //7 Numbers "C7"=> array( 61, 62, 64, 65, 69, 70 ), //6 Numbers "C8"=> array( 71, 74, 75, 76, 77, 78 ), //6 Numbers "C9"=> array( 82, 83, 85, 87, 88, 89, 90 ) //7 Numbers );

The above array has 60 Numbers to be filled out of 108 MATRIX BLOCK / CELL which meets the condition that for a FULL BLOCK containing 4 MINI BLOCKS WITH 3 ROWS (max. allowed) EACH

I have been able to generate this without any issue meeting all the conditions of the Columns

My Allocation Matrix Array will look like

array( "R1"=> array( "C1"=> true, // Means that MATRIX BLOCK R1C1 will be NOT EMPTY "C2"=> false, // Means that MATRIX BLOCK R1C2 will be EMPTY "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> false ), "R2"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> false ), "R3"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> false, "C8"=> false, "C9"=> true ), "R4"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> false ), "R5"=> array( "C1"=> false, "C2"=> false, "C3"=> false, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> true ), "R6"=> array( "C1"=> true, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R7"=> array( "C1"=> false, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R8"=> array( "C1"=> true, "C2"=> false, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R9"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R10"=> array( "C1"=> false, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> false, "C9"=> false ), "R11"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> true, "C9"=> false ), "R12"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ) );

In the above array R stands for Row, C for Column, TRUE/FALSE (Boolean) means that if TRUE a Number can be filled in the resulting MATRIX BLOCK / CELL ( Row[Number]Column[Number] ) else if FALSE the MATRIX BLOCK / CELL shall be EMPTY

The result for the above shall be

PROBLEM : 

I am unable to understand what should possibly be the logic & loop used here for creating a MATRIX ALLOCATION MAP as shown above

I have tried while, foreach & for but unable determine the perfect combination which would meet the conditions.

(Tried all of the above with Nested Loops also)

How can i save array from inputs, witch is $igraci and it have 5 values, to mysql base, i tryed but in mysql it shows Array.

            <input class="button" type="submit" name="submit" value="Dodaj" />&nbsp;&nbsp;
            </p>
        </form>
Now i wonna save this igraci[] array in mysql, i tried like this but it doesn't work:
$igraci = $_POST['igraci'];
$query = "INSERT INTO klanovi (naziv, website, email, igraci) VALUES ('{$naziv}', '{$website}', '{$email}', '{$igraci}')";
$result = mysql_query($query, $connection);

How can i do this?
Thanks..

I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription.

I am trying to pull the shortdescription from the listings table with the query

$shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' ")));

The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories


Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462

The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them.

Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data?

So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : 

<?php
    $myStr = (
        "00ffff", "00cccc", "009999", 
        "007777", "004444", "001111", 
        "01ffff", "01cccc", "019999"
    );
?>

& turn it into 3 separated arrays like : 

<?php
    $myNewArrs = [
        Array1 ( 3 ), 
        Array2 ( 3 ), 
        Array3 ( 3 ), 
    ];
?>

which REALLY looks like : 

<?php
    $myNewArrs = [
        Array ( "00ffff", "00cccc", "009999" ), 
        Array ( "007777", "004444", "001111" ), 
        Array ( "01ffff", "01cccc", "019999" ), 
    ];
?>

?

Any assistance is most-definitely appreciated!

Thank you & have a great afternoon!

Hello all,

I have yet again trouble finding a logical solution to my problem.
I'm fetching an array which can hold 1 or more values.
The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values.

I can't explain it further, so here's the code so far:

Code: (php) [Select]
$files = mysql_fetch_array($get_files);

$a = count($files);

$i = 1;
while ($files) {
$variablename = 'fileName' . $i;
$$variablename = $files['fileName'];
$i++;
}

$output =  array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are?


This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works?

Thank you.
