PHP - Remove Part Of My Array..

Hello,

I'm trying to store the match I get in $result to a variable so that I can easily compare its other values against other values. Here is my code..

//loop through new orders array
foreach ( $orders as $order ) {
	
	//compare job number and line item against database information for a match
	if ( array_search ( $order[ 'job_number' ], array_column ( $result, 'job_number' ) ) !== false && array_search ( $order[ 'line_item' ], array_column ( $result, 'line_item' ) ) !== false ) {
		
		$db_match = key($result);
		
		echo '<br><br>'.$db_match.'<br><br>';
		
		echo 'Job: ' . $order['job_number'] . '/Line Item: ' . $order['line_item'] . ' was found<br>';
	
	//new order which doesn't exist in database
	} else {
		echo 'Job: ' . $order['job_number'] . '/Line Item: ' . $order['line_item'] . ' was not found<br>';
	}
}

When I do $db_match = key($result); I get 0 each time and when I do: 

$db_match = array_search ( $order[ 'job_number' ], array_column ( $result, 'job_number' ) ) !== false && array_search ( $order[ 'line_item' ], array_column ( $result, 'line_item' ) ) !== false;

I get 1 each time...which I assume is the number of matches which meet that criteria instead of the array key I found a match on.

I am trying to write a dirty script that removes duplicate rows from a multidimensional array.

I want to be able to edit the function and spit the duplicates out to a CSV file.

Here is my test file:


$fullArray = array(array('Jim', 'Jones'),
array('Pete', 'Pumpkin'),
array('Barak', 'Obama'),
array('Jason', 'Newstead'),
array('Toby', 'Keith'),
array('Jim', 'Jones'),
array('Jim', 'Nelson'));


echo "<h1>Original</h2>";
for($i=0; $i<count($fullArray); $i++) {
echo $fullArray[$i][0] . " " . $fullArray[$i][1] . "<br />";
}

echo "<h2>Checked</h2>";
$cleanArray = array();
$cay = array();
$nn=0;
$dup=0;
// Loop the entire input array
foreach ($fullArray as $index => $item) {
echo "foreach index:$index<br>";

        // Start an internal pointer
for ($f=0; $f<count($fullArray); $f++) {
echo "for $f ";
                // if the index is lower or the same as the pointer, skip it to cut down on time
if ($f > $index) {
                        // if the rows are the same...
if($fullArray[$f][0] == $item[0] && $fullArray[$f][1] == $item[1]) {
echo "$item[0] DUP<br>";
                                // remove it from the array
$cay = array_push($cleanArray, array($item[0], $item[1]));
array_pop($fullArray[5]);

$dup++;
} else {
                                // not a duplicate
echo " not a dup<br>";
}

} else {
echo "ON THIS ONE<br>";
}
}
echo "<br><br>";
}
echo"<br>$dup duplicates found<br><br>";
print_r($fullArray);
echo "<br /><br>";
// print_r($item);
print_r($cleanArray);
?>


When I spit out the new fullArray variable, it still has an element from the duplicate record.

This is what I get for the output of the full array after the duplicate was removed:
Quote

Array ( => Array ( => Jim [1] => Jones ) [1] => Array ( => Pete [1] => Pumpkin ) [2] => Array ( => Barak [1] => Obama ) [3] => Array ( => Jason [1] => Newstead ) [4] => Array ( => Toby [1] => Keith ) [5] => Array ( => Jim )[/b] [6] => Array ( => Jim [1] => Nelson ) )

Is there a built in function to remove empty array values for example:

change

Array (
    [0] => Bob
    [1] =>
    [2] => Ryan
    [3] => Jane
)

to

Array (
    [0] => Bob
    [1] => Ryan
    [2] => Jane
)


Thanks

Hello guys,

need some help.


Let us say i have an array =

2011 ipad
2011 ipad review
2011 ipad price
2011 ipad design
2011 ipad reviews
review 2011 ipad
2011 ipad feature


I would like to review all the array elements that contain "review"...So the final array should look like

2011 ipad
2011 ipad price
2011 ipad design
2011 ipad feature

Thanks

guys please help,

i have an array(52,51,52)
here i want to insert first & last elements into DB, not  second one does not follows the series

another array (52,52,53)
in this case insert first 2 elements into DB since last element does not follow the series.

how is this possible?

Just a quick one, new area for me.

I have an array which is looped against another array, if the two values from each ever match then an event occurs, if not then something else.

If a match does occur i then want to remove the said value from one of the arrays... is this really all i need to do, seems too simple:

unset($saved_dont_use[$j]);

I can't for the life of me understand how to perform this so I need some professional help here.

I have a large array that contains some garbage every Nth and Nth + 1 element that needs to go away. array_filter doesn't work with keys but anyhow, i wouldn't know how to design the function.

My keys are numeric, starting from 0. The keys I want to remove are part of this sequence: 8, 9, 18, 19, 28, 29 ...

Can someone help me design a generic function to remove these keys?

function filter_keys($array, $n, $offset) {}

$new_array = filter_keys($array, 10, 8 );

I would maybe have to run this function twice, once for 8 offset and once for 9 offset.

Hi,

I have an array filled with values like this:

Code: [Select]
string(1) "Acer 1"
string(2) "Acer 2"
string(3) "Dell 1"
string(4) "Dell 2"
string(5) "Dell 3"
string(6) "Dell 4"
string(7) "Acer 3"
string(8) "Acer 4"
Is there a way to successfully remove all array strings that starts with a given value like "Acer"?

I tried with this snippet, does not work:

Code: [Select]
foreach($array as &$value) {

  if(preg_match("/^Acer/", $value)) {
  unset($value);
} }

Any ideas will be appreciated!

Hi guys!

i got this code:
Code: [Select]
<?
$x = "abcde";

str_split($x);
for ($k=0; $k<=119; $k++){
$ax = array($x[0],$x[1],$x[2],$x[3],$x[4]);
shuffle($ax);
    $text = implode("", $ax) . "";
echo $text;
echo "<br />";
}
?>
if you test it you see that it is working but giving me allot of duplicates results!

there is a way to ignore duplicaes while it is runing?

thanx.

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.

Hello I have a while loop which outputs countrys from the database (im making a "filter by" function). For example, the loop outputs:


Denmark
Belgium
Holland
Brazil
Japan
Brazil
Denmark


I want to sort these alphabetically and then remove duplicates... Can somebody explain to me how? I don't know how to get them into an array to do it...

Hello. I am editing a plugin that is grabbing a multidimensional array, then breaking it out into a foreach statement and doing stuff with the resulting data.

What I am trying to do is edit the array before it gets to the foreach statement. I want to look and see if there is a key/value combination that exists, and if it does remove that entire subarray, then reform the array and pass it to a new variable.

The current variable Code: [Select]
$arrSlides returns several subarrays that look like something like this (I remove unimportant variables for the sake of brevity):

Code: [Select]
Array (
[0] => Array (
[slide_active] => 1
)
[1] => Array (
[slide_active] => 0
)
)
What I want to do is look and see if one of these subarrays contains the key slide_active with a value of 0. If it contains a value of zero, I want to dump the whole subarray altogether, then reform the multidimensional array back into the variable Code: [Select]
$arrSlides.

I have tried a few array functions but have not had any luck. Any suggestions?

Thanks in advance,
Jason

When I remove 1 session item using this it works fine when I select more than 1 item to be removed I get unexpected results, I have checked the outputted html to see what positions get echoed into the remove check box and they are correct, so I guess the problem lies in my remove code

here is the part of the form that sends the remove check box

<?php 
for ($basket_counter=0;$basket_counter<$_SESSION['ses_basket_items'];$basket_counter++) {
   $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]);
    $quantity=$ses_basket_amount[$basket_counter];
$code=$ses_basket_stockcode[$basket_counter];
$itemID=$ses_basket_id[$basket_counter];
    $name=$ses_basket_name[$basket_counter];
$image=$ses_basket_image[$basket_counter];
$size=$ses_basket_size[$basket_counter];
$sizechoice=$ses_basket_sizechoice[$basket_counter];
// create array from sizes and make the option box selections
if ($sizechoice!="" && (!in_array($sizechoice, array('One Size', 'one size', 'free size', 'Free Size', 'Adjustable', 'adjustable')))) { 
// add size trigger
$sizelist="add";
//create the array
$sizepick=explode(",", $sizechoice);
} else { $sizepick=$sizechoice; }
// adjust gst for AU customers
if ($country=='AU') { $price=sprintf("%01.2f",($price*1.1));
$unit=sprintf("%01.2f",($price/$quantity));
 }
else
{ $unit=sprintf("%01.2f",($price/$quantity)); }
?>
<tr>
  <td align='center' class='rescon' style="border-bottom:solid #330000 1px;"><input type="checkbox" name="remove[<?php echo $basket_counter; ?>]" value="<?php echo $basket_counter; ?>" /></td>


and here is the part of the code that processes the removal of the items

$remove = $_POST['remove'];
if (isset($remove) && ($remove!='')) {
        foreach($remove AS $key => $remove_position){
array_splice ($ses_basket_name, $remove_position, 1);
array_splice ($ses_basket_amount, $remove_position, 1);
array_splice ($ses_basket_price, $remove_position, 1);
array_splice ($ses_basket_stockcode, $remove_position, 1);
array_splice ($ses_basket_image, $remove_position, 1);
array_splice ($ses_basket_size, $remove_position, 1);
array_splice ($ses_basket_sizechoice, $remove_position, 1);
array_splice ($ses_basket_id, $remove_position, 1);
$_SESSION['ses_basket_items']--;
}
}


I am using a form with checkboxes named remove[$remove_position] and the positions in the form are correct for each item in the array, but when I select more than 1 item to delete they are not always the correct items only the first 1 selected.
What am I doing wrong here??
