PHP - Working With Arrays In Forms

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

Code: [Select]
function sql_read( $dbname,$dbusername,$dbpassword )
{
$names = array();
$password = array();


$connect = @mysql_connect("mysql11.000webhost.com",$dbusername,$dbpassword) or die("Could Not Connect");
@mysql_select_db ($dbname) or die("Could not find DataBase");


$query = mysql_query("select * from users");
$numrows = mysql_num_rows($query);

if ($numrows > 0){

while($row = mysql_fetch_assoc($query)){

$names[] = $row["uname"];
$password[] = $row["password"];
$id = $row["id"];

}
$return = array($names,$password,$id);

}else{
$return = array();
}


return $return[];
}



$names = array();

$names = sql_read("XXXXXX","XXXXXX","XXXXXXX")[0];


The error i get is
Code: [Select]
Parse error: syntax error, unexpected '[' in /home/a5480952/public_html/sql/index.php on line 28
Line 28 is "$names = sql_read("XXXXXX","XXXXXX","XXXXXXX")[0];"

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?

I've spent many hours trying to solve this with no success. So, here's my challenge.
Sample Data from DB:
Month   Year           Measure
5           2010         164
6           2010         31
7           2010         20
8           2010         10   
9           2010         10
10         2010         10
12         2010         10
1           2011         10

I need to display this data in a chart, but notice that I don't have data for month 11 and the chart must show all months with data and the month that I don't have data for (11 in this case) will show an interrupted line.
I need to put this into an array to display month/year as label and measure as chart value.
So, the above data needs to become:
Month   Year           Measure
5          2010           164
6          2010           31
7          2010           20
8          2010           10   
9          2010           10
10        2010           10
11        2010           --
12        2010           10
1          2011           10

The issue here isn't the chart, but how to add the missing month (11) to the array and keep the measures corresponding with their months.

Thank you.

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.

Hello! i want to store data in a array (as seen in the code). Im trying to make it so that a php code search through the arrays and find the correct one. once it does it tells me. I dont know if im close, How ever this is what i have.


$carrier = $_POST['carrier'];

$carriers = array(
array("verizon","tmobile","sprint","att","virgin","textnow","metro","unknown"),
array("@vtext.com","@tomomail.net","@messaging.sprintpcs.com","@txt.att.net","@vmobl.com","@textnow.me","@mymetropcs.com","@teleflip.com")
            );

If ($carrier = 

I have ticket's for my lottery system.

Somone chooses 3 random numbers out of 36, it will show

1|20|30

but now I want to beable to have my Members BUY multiple Tickets! So then I added a comma between the 3 arrays


So the code will look like this when they select the balls they want

Code: [Select]
1|20|30,20|10|5 /etc /etc

But now I have 1 problem.

How do I go about validating the arrays for each COMMA inside the | ARRAY?  Cause let's saY I don't want anyone  to Submit a ball number higher then "36" how would I go about making it so it checks through each array and if it's higher then 32 I can give them a Error?

Also, I each Ticket costs (5 Forum Gold) so the above code would be a total of 10 Forum Gold, because they're "2" Tickets being bought, how would I go about making a $counter++ in the arrays to count only the "," so I can tell how much Gold the member needs to have before he purchases

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?

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 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.

Hi i'am try to insert multiple data on a single submit, but i'm a total noob to Arrays, can any one help me out here... one of the members send me this out, but still i can figure it out how to insert the fields onto my database. it inserts but doesnt get the valuee.. Please help!

if(isset($_POST['save']))
   {
   unset($_POST['save']);
   $i = count($_POST['id']); $x = 0;
   for($x=0; $x <$i;$x++){
      foreach($_POST as $data =>$d){
      echo $data.'-'.$d[$x].'<br/>';
      $insert = mysql_query("insert into tbl_grades");
//sql statement here (example): insert into table name (value of $data) values( value of$d[$x]) --

can anyone help me with this , how can i query to get the value of  this,
//HOW DO I MAKE MY SQL QUERY TO SAVE THIS OUT, I KNOW THIS IS MY PROBLEM IN THE QUERY....

here's my HTML

 <input name="id[]" type="hidden" value="<?php echo $row['id'];?>" />
 1st<input name="fg[]" type="text" id="fg[]" size="1" value="<?php  $g_sub['sub_id'];?>"/>
 2nd<input name="sg[]" type="text" id="sg[]" size="1" value="<?php  $g_sub['sub_id'];?>"/>

4th <input name="forg[]" type="text" id="forg[]" size="1" value="<?php  $g_sub['sub_id'];?>"/> ---- sub_id stands for subject id

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 some similar arrays. How I can combine them to shuffle the new array?

hi all,

how can i make this array dynamic. E.g, i want the numbers to be pulled from a database...
