PHP - Add Username And Values To Php Array

While we're on the subject, is there a way to ensure that the first letter of a name is captalized, and the rest lowercase?  Or is this best handled later on, when the name is being used and called from the DB.

PS: some of us comment are code as to WHAT we are doing because we're just not that good yet, and we need to explain it to ourselves.

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.

Hi there,

Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway)

My question is: is there a short-hand way to use a value from an associative array as the key in another associative array?

So for example, given this array:

$the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....);

then this kind of foreach loop doesn't work

Code: [Select]
$new_data = array();
foreach($the_array as $element){
$new_data[$element['name']] = $element['value'];
}

Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it?

Cheers,

PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails.

I have mysql select query shown below retrieving data from a database:

$sql = "
SELECT 
	student, sum( test_score ) as score
FROM 
	test
INNER JOIN 
	level 
ON 
	test.level_id = level.level_id
GROUP BY 
	student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
      while ($row = $result->fetch_array(MYSQLI_ASSOC))
       {
	    var_dump($row);
       }
}

On inspection of the retrieved array with var_dump(), i have these result below:

array (size=2)
  'John' => string 'English' (length=2)
  'Score' => string '20' (length=3)

array (size=2)
  'Mary' => string 'Math' (length=3)
  'Score' => string '35' (length=3)

array (size=2)
  'Samuel' => string 'Physics' (length=3)
  'Score' => string '5' (length=3)

 How do I get at and print out the highest score from this set of array values within this context.
 I tried this echo max($row['count']) but i understandably got this feedback:
Warning: max(): When only one parameter is given, it must be an array   Thanks.

I have the following  array structu

I have an array created to control the down states of the my buttons in my navigation. Which is working well. This array will have quite a few strings in it before I'm done.

I then want to conditionally load a CSS file for all the files in that array with the exception of two, is this possible?

In plain in english I want to say If in array apart from these values then load my css file.

My array (will have more values when complete)

Code: [Select]
$otherTitles = array('Product Selector', 'Avon Range', 'Knightsbridge Range', 'Kingston Range' );

My code to load a css file

Code: [Select]
<?php if (in_array($title, $otherTitles)) { ?>
<link rel="stylesheet" type="text/css" href="homepage.css"/>
<?php } ?>

I want all titles in the otherTitles array to get this CSS file apart from two Product Selector and Avon Range.

Thanks

I need to some how pull comma separated images $data[23] from this $data array and then put them into there own array so I can insert them into separate rows in a database.


    
This is the provided array:

$data[0] => VIN
$data[1] => StockNumber
    
...(all the other number here)
    
$data[23] => Image_URLs (comma seperated)
$data[24] => Equipment


// I need something like this (obviously doesn't work?!@#)

$delimiter = ",";
$img = explode($delimiter, $data[23]);

foreach($img as $pic){
$sqlPic = "insert into class_prodimages (pid image rank) values('".$LastId['id']."', '$pic', '".rand(1,20)."')"; 

}



Any help here?

Hello there again!   I have the following construct of array now (schematics):

array[0]
	array[id] = "1"
	array[title] = "title"
array[1]
	array[id] = "3"
	array[title] = "another title"

Now what i want to do, is to assign the parent-array keys to the IDs of it's contents.   This is what it should look like:

array[1]
	array[id] = "1"
	array[title] = "title"
array[3]
	array[id] = "3"
	array[title] = "another title"

How do I do that again? I know I did this some years ago, but I can not remember how.

How do you get the values in an array and name them as variables?

Lets say I want the 0 and the 2...

Array ( => 02.02.2011 [1] => 97% [2] => 538 [3] => 20 [4] => 63,247 (2.20) [5] => 77,639 [6] => 195,617 [7] => 09.13.2010 )

as you can see, there are key value pairs like this,
Code: [Select]
[items_name1] => Product Name 1
[items_name2] => Product Name 2
[items_name3] => Product Name 3

those keys aren't constant, I mean, it came from a shopping cart, so the item name depends on how many items were placed in the shopping cart to be purchased.. now my question is,
How to loop to that post array, and get only the item_names plus their corresponding values ?, because I need them and save in a db table 

I am working in wordpress and things are going good. I made a form, filled it with values and have been able to store those values in a database using a wordpress function. Now my issue is that I want learn how to write them into an array and store them that way. I have been looking at several different ways but can't figure out how to code it. This is my code now

Code: [Select]
function add_slider_box(){
  global $post;
$imageurl = get_post_meta( $post->ID, 'imageurl', true );
$imagelink = get_post_meta( $post->ID, 'imagelink', true );
$imagecap = get_post_meta( $post->ID, 'imagecap', true );

?>
<div style="width: 50%" class="sliderbox">
        <p><label for="imageurl">Image Url: <br />
            <input type="text" class="widefat" id="imageurl" name="imageurl" value="<?php if( $imageurl ) { echo $imageurl; } ?>" /></label></p>
        <p><label for="imagelink">Image Link: <br />
        <input type="text" class="widefat" id="imagelink" name="imagelink" value="<?php if($imagelink) { echo $imagelink; }?>" /></label></p>
        <p><label for="imagecap">Image Caption: <br />
            <input type="text" class="widefat" id="imagecap" name="imagecap" value="<?php if( $imagecap ) { echo $imagecap; } ?>" /></label></p>
           
            <button class="remove_slide button-secondary">Remove This Slide</button>
    </div>
<?php

}

function bigBusiness_save_slider_options($post_id){
global $post;

if( $_POST ) {
update_post_meta( $post->ID, 'imageurl', $_POST['imageurl'] );
update_post_meta( $post->ID, 'imagelink', $_POST['imagelink']);
update_post_meta( $post->ID, 'imagecap', $_POST['imagecap'] );
}

}

so the update_post_meta function is what is saving the information into the database. How do I put that into an array? I was thinking

Code: [Select]
foreach($_POST as $slides)
    $slides[] = array(
               'imageurl' => '$_POST['imageurl'],
               'imagelink' => $_POST['imagelink'],
               'imagecap' => $_POST['imagecap'];
            );

I have been able to use the data out of the database by creating a function
Code: [Select]

function get_half_slider_slides() {
global $post;
$imageurl = get_post_meta( $post->ID, 'imageurl', true );
$imagelink = get_post_meta( $post->ID, 'imagelink', true );
$imagecap = get_post_meta( $post->ID, 'imageurl', true );

return array( $imageurl, $imagelink, $imagecap );
}

and then calling that function in my code like this $slide =  get_half_slider_slides();

I thought since it returned an array that I would be able to do this $slides['imagelink'] $slides['imageurl'] but it doesn't work. What I am trying to do is populate the nivo-slider ( http://nivo.dev7studios.com ) with images from the database. I have been following a tutorial but since the license on the tutorial doesn't cover reusing the code, I am trying to rewrite it in a way that doesn't violate the license agreement. This code is so far is hacked together but completely different from the tut. Can you help?

Thanks

Basically I am pulling data from an XML feed on wowarmory.com
Everything is working as far as getting the item names and even a list of the item levels.
What I am trying to do now is add together all of the item levels in to one value that I will call $calc (I will then divide this by 16 to find the average item level).

I am using a foreach loop to echo the Item Name and it's corresponding item level. I am now trying to grab the item level on each loop so I can add them all up and store them in $calc for further manipulation outside of the loop. I am a complete novice but learning, How would I go about achieving this?

Of course the code I have atm is re-defining $calc every loop, so naturally it isn't working.
Here is my current code:
//Get the UID for each item the character has
    //Then look up the name for that item
    foreach($char_xml->characterInfo->characterTab->items->item as $item)
    {
        //get the item id
        $item_id = $item->attributes()->id;
        //get the xml doc for that item from wow armory
        $url = "http://www.wowarmory.com/item-info.xml?i=" . $item_id;
        $data = fetchXML($url);
        //create a SimpleXML object to parse the xml
        $item_xml = new SimpleXmlElement($data);
        //print the item's name
        echo "<b> Item Name: </b>" . $item_xml->itemInfo->item->attributes()->name . "</br>";
echo "<b><i> iLvL: </i></b>" . $item_xml->itemInfo->item->attributes()->level . "</br>";
//obviously this is wrong, because It is redefining $calc every loop
$calc=$item_xml->itemInfo->item->attributes()->level;
    }
//print the total item level
echo $calc;

I'm trying to split a url into segments so that a url would be stored in an array. 

Example:
A url like this http://localhost/application/blog/view/Test-Blog-Entry/1

Would look like this in an array:
Code: [Select]
array('blog', 'post', 'Test-Blog-Entry', '1');
It's an MVC url so 'blog' would be controller, 'post', would be method and the last two would be variables.  I want to display the variable values of the array.

Is there an easy way to do this?

I have the following multidimensional array;

Array
(
    => Array
        (
            [value] => Alarm
            [safe] => Alarm
            [view] => Alarm
        )

    [1] => Array
        (
            [value] => Deadlocks
            [safe] => Deadlocks
            [view] => Deadlocks
        )

    [2] => Array
        (
            [value] => Security Doors
            [safe] => Security Doors
            [view] => Security Doors
        )

)

I'm trying to implode the array to end up with an output like "Alarm, Deadlocks, Security Doors".

But I cannot for the life of me work out the correct PHP.  I'm assuming i need some foreach loop? Any help would be greatly appreciated.

      ),
    ),
  ),
)[]

So, for example i have repeated the date 2020-10-20, one with "tempos =1" and another with "tempos=3"

I'm looking to have only one date with concatened tempos field

Example

array (
        'dataAula' => '2020-10-20',
        'tempos' => 1+3,
        'tempos2' => 'Terça',
        'total' => 33,
      ),

So what i have now is this code but not getting what i need

 

foreach ($finalCronograma as $sub) {
                $row = current($sub);
                if (isset($result[$row[0]['dataAula']])) {
                    $result[$row[0]['dataAula']]['tempos'] .= '+' . $row[0]['tempos'];
                } else {
                    $result[$row[0]['dataAula']] = $sub;
                }
            }

 

any help?
