PHP - Problem With Arrays

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?

I can't work out the quotes around this...

$bookingID['$row['id']'] = $row['id'];
echo $bookingID['$row['id'];'];

Parse error: parse error, expecting `']''

What would fix this?

Code: [Select]
$data=array('user1'=>'pass1','user2'=>'pass2');

now i would like that echo prints out the user1 word.

Code: [Select]
echo $data[?what here?];

I have an array of dates and then i have an array for rates/prices for the days of the week. For example
Code: [Select]
<?php
$rate = array();
$rate['monday'] = 91.11;
$rate['tuesday'] = 92.22;
$rate['wednesday'] = 93.33;
$rate['thursday'] = 94.44;
$rate['friday'] = 105.55;
$rate['saturday'] = 106.66;
$rate['sunday'] = 90.00;

$dateMonthYearArr = array();
       $datemonthYearArr['0'] = "2011-05-06";
       $datemonthYearArr['1'] = "2011-05-07";  
       $datemonthYearArr['2'] = "2011-05-08";
       $datemonthYearArr['3'] = "2011-05-09";
       $datemonthYearArr['4'] = "2011-05-10";
       $datemonthYearArr['5'] = "2011-05-11";
       $datemonthYearArr['6'] = "2011-05-12";
?>
I have written this to sort through the $dateMonthYearArr to determine the dates day of the week
Code: [Select]
<?php
foreach ($dateMonthYearArr as $date) {
        $sum = 0;
$day = strtotime($date);
        $day_name = date("l", $day);
echo $day_name."<br>";
}

Now i'm trying to figure out how to work in the day rate array. I'd like to match up the $day_name of $dateMonthYearArr to the key of the rate array, grab that value and then add it to $sum.

Hi,

I need to do this:
Write a method to quickly find the array index position of a given number in a ascending sorted array of numbers. e.g. in an array { 1, 2, 5, 10, 102 }, the array index position of a given number 5, would have an answer of 2. We're looking for an answer that's better than O(n).

I was using php's built in methods but I need to do this with a basic function using no helper methods.

Can anybody help me out with this?

Thanks in advance.

Hello,

I have an array, $solutions, and a separate indexing array, $solution_order.  From the $solution_order array (developed from the $order variable, where each $order variable looks like '0321' or '3021'), I'd like to create a new array $ordered_solutions, which indexes on the values picked from the $solution_order array.  For example, if my $solutions array is (Big, Small, Fat, Skinny) and my $solution_order array is (2,3,1,0), then the final results should be (Fat, Skinny, Small, Big).  I've written down what I have so far.  Any thoughts about how to move this forward would be appreciated.

Thanks!
function GetOrder($solution, $wrong1, $wrong2, $wrong3, $order) {

$solutions = array( $solution,

               $wrong1,

$wrong2,

               $wrong3);

$solution_order = array(substr($order,0,1),

       substr($order,1,1),

       substr($order,2,1),

      substr($order,3,1));
$ordered_solutions = array();

//what do to here??

return $ordered_solutions;
}

Let's say I have an array like this:

Man1(0), Man1(1), Man1(2), etc.
Man2(0), Man2(1), Man2(2), etc.
Man3(0), Man3(1), Man3(2), etc.
...

and I want to loop through the array.
I know I can do:
Code: [Select]
$i=0;
while $i<=99
{//...do something with Man1[$i];}
i++;
but can I also do a loop with each Man?
Like:
Code: [Select]
$i=0;$a=1;
while $i<=99
{//...do something with Man$a[$i];}
i++;a++;
I've written all the code for each Man separately and I'm thinking there's got to be a way to shorten the code with another loop, but I don't know how.
Hope that makes sense.
Thanks.

Arrays in C are fixed length:

#define MAX_SIZE 5

int main(void){
  int n[ 5 ]; 
  for(int i=0;i<MAX_SIZE;i++){
    n[i]=i;
  }
  return 1;
}

If I try to insert an eleement into the array, it will result in undefined behavior.   Java compensates for this by creating an actual object class called ArrayList or LinkedList, the former an internal store of array elements that dynamically resizes and the latter just a node tree with pointers to next and previous elements.

ArrayList<Integer> arr = new ArrayList<Integer>();
arr.add(1);
arr.add(2);

It seens that the array() construct in PHP is not a function or a class but an internal construct. How does it dynamically resize arrays?

Hello,

I'm trying to extract information about a ticket through osTicket SOAP API, but I can't seem to figure out how!

This is the return from the script (var_dump):


array(1) {
  [0]=>
  object(stdClass)#2 (2) {
    ["question"]=>
    object(stdClass)#3 (4) {
      ["id"]=>
      int(25)
      ["created"]=>
      string(25) "2011-01-05T01:19:43+01:00"
      ["name"]=>
      string(4) "test"
      ["message"]=>
      string(4) "qasd"
    }
    ["answers"]=>
    array(1) {
      [0]=>
      object(stdClass)#4 (4) {
        ["id"]=>
        int(25)
        ["created"]=>
        string(25) "2011-01-05T01:25:06+01:00"
        ["name"]=>
        string(17) "Andreas Haakonsen"
        ["message"]=>
        string(3) "ler"
      }
    }
  }
}

A ticket can have several answers.

I just can't seem to figure out how to extract/use this data and present it on my webpage. Too many arrays for me to understand I guess :p

Is there anyone who can help me with some small code to help me figure this one out?

Thanks!

Ok i am trying to create a simple program that will allow mwe to use an array with 8 numbers, the output form should show the numbers in their original order that the user inputs them, in numerical order, Highest number, lowest number and then the average number. I am confused on what logic i would use to do this. If anyone could help me get started it would be much appreciated. here's waht i have so far.
Code: [Select]
<?php
$Num1 = $_POST['fielda'];
$Num2 = $_POST['fieldb'];
$Num3= $_POST['fieldc'];
$Num4 = $_POST['fieldd'];
$Num5 = $_POST['fielde'];
$Num6 = $_POST['fieldf'];
$Num7 = $_POST['fieldg'];
$Num8 = $_POST['fieldh'];
$Numbers = array(1,2,3,4,5,6,7,8);
$big = max($Numbers);
$small = min($Numbers);
$average = array_sum($Numbers) / 8; 
?>

I have created two classes. One is called 'move' and the other 'unit'. To make my example easier to follow, I shall use the much loved pokemon series to explain my dilemma.

Here are the class declarations.


new class unit {
var $name, $moves;

public function newUnit($name, $moves) {
$this->name = $name;
$this->moves = $moves;
}

}

new class move {
var $name, $attack;

public function newMove($name, $attack) {
$this->name = $name;
$this->moves = $moves;
}

}


Now I shall instantiate these classes (if that makes sense xD) - I just started OOP yesterday, do mind my ignorance.



$unit = array(); 
$move = array();

$unit[0] = new unit; $unit[0]->newUnit("picachu",array("thunderbolt","quick-attack"));



Now, let's say I want to populate the $move array with the moves in the unit object (thunderbolt and quick-attack). I can retrieve their attack values from a database:



$thunderboltAttack = 200;
$quick-attackAttack = 40;



I now want to create a function that will create instances of the 'move' class to produce:



$move[0] = new move; $move[0]->newMove("thunderbolt",200);
$move[1] = new move; $move[1]->newMove("quick-attack",40);



Here is my dire attempt to do so:



function createUnits($moves){  //$moves is the array holding the unit's moves

for($i; $i < count($moves); $i++) {

$arr[] =new move;
$arr[count($units) - 1]->name = $moves[0];
$arr[count($units) - 1]->attack = $someAttackData;

}
return $arr;
}

$moves[] = createUnits;



I'm ending up with a multi-dimensional array when I want a linear one like this:



$move[0] = new move; $move[0]->newMove("thunderbolt",200);
$move[1] = new move; $move[1]->newMove("quick-attack",40);




What do I need to do. Do I have to resort to making $move global from within the function and do things that way?

Ok so this link returns HTML

$hitlist = file_get_contents($iMobLink."get_hit_list?user_id=".$iStore[2]."&level=10&auth_key=".$iStore[3]);

now to parse it out I have this

$entry = explode('<entry>', $hitlist);
$hitlist = file_get_contents($iMobLink."get_hit_list?user_id=".$iStore[2]."&level=10&auth_key=".$iStore[3]);
    $user_id = explode('<user_id>', $hitlist);
$user_id = explode('</user_id>', $user_id[1]);
$mobname = explode('<mob_name>', $hitlist);
$mobname = explode('</mob_name>', $mobname[1]);
$paiduser = explode('<paid_user>', $hitlist);
$paiduser = explode('</paid_user>', $paid_user[1]);
    $amount = explode('<amount>', $hitlist);
$amount = explode('</amount>', $amount[1]);
$paid_time = explode('<placed_time_ago>', $hitlist);
$paid_time = explode('</placed_time_ago>', $paid_time[1]);
$level = explode('<level>', $hitlist);
$level = explode('</level>', $level[1]);
$entry = explode('</entry>', $entry[1]);
echo $user_id[0]."\n";
echo urldecode($mobname[0])."\n";
echo $amount[0]."\n";
echo $paid_time[0]."\n";
echo $level[0]."\n";
echo $entry[0];}

Ok now.... this only returns one entry of the xml when there are more than 10. I need it to return all ten+ of the entrys

here is what the xml looks like

Notice there is more than one energy.. now how to I parse it out to where I can define each entry by a variable or something... any help is appreciated.. Thanks

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 all,

how can i make this array dynamic. E.g, i want the numbers to be pulled from a database...
Code: [Select]
$s=array(
"1",
"2",
"3",
"4",
"5",
"6",
"7",
"8",
"9",
"10",
"11",
"12",
"13",
"14",
"15",
"16",
"17",
"18",
"19",
"20"

);


thanks in advance, i just cant work it out

I am trying to learn about sorting and modifying arrays and I am practicing on a book assignment but need some help to grasp what I need to do.

If you go here, you will see how it is supposed to work.

http://198.86.244.3/mabarckhoff/WEB182/ch11_ex1/

I need to write a case to sort the task when you click the sort button and modify when you click that button. The delete button works and the add task works. I understand the sort array and have added that case, but don't know how to get it to work with the submit. Also there is a promote button so would need 'promote' what ever you have chosen in the dropdown menu to the top.

Here is my code.
