PHP - Merging 3 Arrays

Hey!

I have a bunch of text files with one line of text ex. SHS9GW34

I'm trying to write a little php script on my local machine that will take all the files and put all the different codes in the same files in this kind of format:

RGDGIDSG453
EOHBDSBN453
ERGD4535355
etc
etc


Thanks

Hello.
I'm currently trying to write a code to merge two separate images together, but for the life of me I can't find anything that works.

Basically what I'm trying to do is add a "marking" (cat_stripes.png) to a pet image (cat.png). In the future I also want to use this for adding items to pets and things like that.
Both of the images have transparent backgrounds, so that needs to be taken into account. If you haven't got a clue what I'm talking about, look up Wajas or similar virtual pet sites to get an idea of how the markings work.

I just need something simple, since I don't have a site set up yet and I'm just testing some things out for a future project. I don't have any codes at the moment, since nothing has worked so far.
I'm pretty new to GD too (I'm familiar with all the basic php stuff, so don't panic), so you might need to explain some of the more advanced stuff to me.

Any help with this would be really appreciated, thanks. (:

Hello guys,

I don't really know php but I am always been able to copy/paste it and move stuff around on my wordpress website until now.

This last challenge is beyond my skills though (I am sure it will be trivial for you).

So I have this code snippet to show a video duration

    <?php
  global $post;
  $video = cbc_get_video_data( $post );
  if( $video ) {
    echo $video->get_human_duration();
  }
?>

And I have this code to show a post title

if ($show_title) {
        $title_content .= apply_filters( 'uncode_before_body_title', '' );
        $title_content .= '<div class="post-title-wrapper"><h1 class="post-title">' . get_the_title() . '</h1>';
        $title_content .= uncode_post_info() . '</div>';
        $title_content .= apply_filters( 'uncode_after_body_title', '' );
    }

I want to show the video duration right before the post title and in line with it, so inside the h1 tag. How to do that?

Thanks for any help!

 

 

When i upload photos and the name of the photo i would like to be able to overlay a portion of the original photo with another image already in the site directory, and also add the photos name over the top of the overlayed image,  i may have explained this in a confusing way so i have attached an example.

Is this something that can be done using something like GD or imagick, if so could someone please give me a good place to start.

$query = "SELECT
Table1.*,
Table2.A,
Table2.B,
Table2.C,
Table2.D,
Table2.E
FROM Table1
INNER JOIN
Table2 ON Table1.A = Table2.A

Issue is that there are multiple matches for some instances, like so:

Table1.A value = 1777 (only once since it is a UniqueID)
Table2.A value = 1777 (3 records with this ID value)

So I will get 3 records returned since Table1.A matches 3 records in Table2.A. I want to merge the 3 records in Table2 into 1 record and then match that with Table1 where the UniqueID is the same. Make sense?

I currently have a flat file user registration and login in system. I also have a simple guestbook which i didn't code myself, the guest book currently requires the user to type in there name and e-mail address to make a post. how ever i would like them to have to login and if they aren't logged in then don't display the guestbook.

I have tried many solution, but nothing seems to fix this.
The problem is that i put an image with transparency on top of another image, but the transparent pixels still transparent, where they should show some of the image below it.

If you call it with l=100 and p=20 i would get this result http://cl.ly/566Z instead of this http://cl.ly/56OF.

Here is the source code and I have attached the images:
Code: [Select]
<?php
header('Content-type: image/png');
echo imagepng(progressbar($_GET['l'], $_GET['p']));
function progressbar($length, $percentage)
{
$length = round($length / 2) * 2;
$percentage = min(100, max(0, $percentage));
if($length > 0)
{
$bar = imagecreate($length, 14);
imagealphablending($bar, false);
imagesavealpha($bar, true);
$empty = imagecreatefrompng('Empty.png');
imagealphablending($empty, false);
imagesavealpha($empty, true);
$fill = imagecreatefrompng('Fill.png');

Hi, I'm trying to combine two images - an uploaded image and a permanent. First I try to resize them to the same dimensions. Why I resize the uploaded image to the dimensions of permanent, everything works fine. But when I do the opposite, the images just don't merge, and the output is just the permanent image with resized dimensions. Anyone knows why? Here is my code:

<?php
if( isset( $_FILES['image'] ) ){
	$desired_width = 360;
	$desired_height = 360;

	$layers = array();
	switch($_FILES['image']['type']){
		case "image/jpeg":
			$source_image = imagecreatefromjpeg($_FILES['image']['tmp_name']);
		    break;
		case "image/gif":
			$source_image = imagecreatefromgif($_FILES['image']['tmp_name']);
			break;
		case "image/png":
			$source_image = imagecreatefrompng($_FILES['image']['tmp_name']);
			break;
	}
	
	$frame = imagecreatefrompng("1.png");
        $desired_width = imagesx($source_image);
        $desired_height = imagesy($source_image);
        $virtual_image = imagecreatetruecolor($desired_width, $desired_height);
        imagecopyresampled($virtual_image, $frame, 0, 0, 0, 0, $desired_width, $desired_height, 360, 360);

	$layers = array($source_image,$virtual_image);

	$image = imagecreatetruecolor($desired_width, $desired_height);

	// to make background transparent
	imagealphablending($image, false);
	$transparency = imagecolorallocatealpha($image, 0, 0, 0, 127);
	imagefill($image, 0, 0, $transparency);
	imagesavealpha($image, true);

	imagealphablending($image, true);
	for ($i = 0; $i < count($layers); $i++) {
	    imagecopy($image, $layers[$i], 0, 0, 0, 0, $desired_width, $desired_height);
	}
	imagealphablending($image, false);
	imagesavealpha($image, true);

	header('Content-type: image/png');
	header('Content-Disposition: attachment; filename="new_profile.png"');
	imagepng($image);

Hello,

I want to 'join' two corresponding array values together as in the example below.

$one = array('tomato', 'ham', 'bacon');
$two = array('soup', 'sandwich', 'roll');

$final=array(?)

//Desired answer =  (tomatosoup, hamsandwich, baconroll)

Is there a php function that can do this, or a series of functions? I am aware of array_merge but this only alternates the values from what I can see.

Ideally there should be a check performed that the two are the same length before completing a merge.

New to this, many thanks!

I have this thing that i am trying to make but i cant get it to work.. can anyone help?

Please help... i REALLLLD need help with this.. ask questions if you want to know more about what i am trying to do... thanks!

I'm having troubling with trying to create a function to spit out a single array with the following array. I can write it in a away that looks through the arrays manually. 

the results i am trying to generate is that each item in generated array.

Array to convert

array(
    "account" => array(
        "login",
        "register",
        "logout",
        "edit",
    ),
    "p" => array( 
        "report",
    ),
    "array1.0" => array( 
        "array2.0" => array(
            "array3.0",
            "array3.1
        ),
        "array2.1",
    ),

generating the array will look like this

 

Array ( 
[0] => account 
[1] => account/login 
[2] => account/register 
[3] => account/logout 
[4] => account/edit 
[5] => p 
[6] => p/report 
[7] => array1.0 
[8] => array1.0/array2.0
[9] => array1.0/array2.0/array3.0
[10] => array1.0/array2.0/array3.1
[11] => array1.0/array2.1

)

The idea is that id generates a single array with combined labels and arrays inside, etc. I just can't figure out how to create a script that will create this array even If I add a new value or array. 

 

I have two arrays, both with the same key values. I'd like to combine them. So for instance...

Code: [Select]
<?php
$array1['abcd'] = array( 'value1' => "blah", 'value2' => "blahblah");
$array1['efgh'] = array( 'value1' => "ha", 'value2' => "haha", 'valuex' => "xyz");

$array2['abcd'] = array('value3' => "three", 'value4' => "four");
$array2['efgh'] = array( 'value3' => "hohoho", 'value6' => "six6");

function combine_arrays($array1,$array2)
{

//*combining*
return $single_array;
}

echo "<pre>";
print_r(combine_arrays($array1,$array2));
echo "</pre>";

/*
would produce 

['abcd'] = ( 'value1'  => "blah",
                 'value2'  => "blahblah",
                 'value3'  => "three",
                 'value4'  => "four" )

['efgh'] = ( 'value1' => "ha",
                 'value2' => "haha",
                'valuex'  => "xyz",
                'value3' => "hohoho",
                'value6' => "six6" )
*/
?>
What's the easiest way to do this?

Okay so here is a very simplified version of my code in order to try and illustrate what I am trying to do:


$C1 = array (174,30);
$C2 = array (165,80);
$S = array($C1, $C2);

foreach ($S as $cluster)
{
$number = '5000';
$another_number = '4565';
$cluster[0] = $number;
}



I feel like this should be really simple but its not working.  So basically I'm trying to change the first value of the array select (e.g. C1 or C2) to whatever is in the variable $number.  Any help would be greatly appreciated.  Thanks

Hi,
I'm having some trouble trying to generate my random string for a name.
This is my code:
Code: [Select]
<?PHP
 function rand_string( $length ) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";

$size = strlen( $chars );
for( $i = 0; $i < $length; $i++ ) {
$str .= $chars[ rand( 0, $size - 1 ) ];
}

return $str;
}
 
 $salt_string = rand_string( 5 );
 
 $test = "1234";
 
 echo "salt_string = $salt_string";
 echo "<br>";
 echo "test = 1234";
 echo "<br>";
 $array = array('$test', '$salt_string');
 echo "<br>";
 echo "array = $array";
 echo "<br>";
 $imploded = implode($array);
 echo "<br>";
 echo "imploded = $imploded";
 
 ?>

And it returns:

salt_string = 8pbAe
test = 1234

array = Array

imploded = $test$salt_string

I don't understand why my imploded variable is not 12348pbAe
