PHP - Operations With Variables From Different Arrays

Okay I have a function that stores data into an Array.  The function takes about 7 seconds to run and through a number of different loops it creates one final array with about 15,000 keys.  I want to recall this data a number of times in different functions, however how can I have this data easily accessible without running the function each time.

EX:
Code: [Select]
function theFunction()
{
   for($x=0;$x,=15000;$x++)
   {
   //Run the loop and store data.
   $string[$x] = //output from other loops and calculations
   }
   return $string
}

//Then later on if I want to recall the data the only way I know how is to do the follow:
$newstring = theFunction()

The only problem I have with this is that it has to re-run the function every time in order to get to the data it spits out.  How can I store this data into another array outside of the function without having to re-run it?

I hope this makes sense.

Thanks.

Hello.  I have a web page that has several operations on it, and I'm not sure the best way to design it.

This is a subscription page were a user can choose different renewal plans.

Before a certain date, the user can "renew" for a certain lower price (operation #1), or he/she can "upgrade" for a certain lower price (operation #2).

After a certain date, the user can choose from one of three plans (operation #3, #4, or #5).

The way I have things design for the "after" part is just creating a form for each one, so that when a user chooses one of them, then I can take the appropriate actions.

My question is this...

1.) Is it okay to have five forms on the one web page to more clearly delineate each request/operation?

2.) Or should I create one form, and then assign a hidden form value to each button so I know how to handle the selection?

I'm attempting to praise(if that's how you say it) txt data into xml with php and have come across a problem I've been unable to solve over the past two days so I'm coming here to ask the php gods for their assistance.

The file I'm prasing contains line after line of real estate data. I understand what I'm doing I think. I've gotten the data in a format that is more usable, taking out the tabs and replacing them with spaces and such. I am creating a series of if than statements which will select the address out of each line even though each line can be different. At the end of the address on each line there is a "S" character which stands for some property I'm not concerned with. I'm simply using the single 'S' to find the end of the address. The lines look like so:
                                                                                                                                                                        \/
403089   RESIDENTIAL   Residential   385000   7610 N Lakeshore Dr.   Harbor Springs   S   3   2   0   None      3   Litzenburger, Boo   Schaffer Real Estate
399562   RESIDENTIAL   Condominium   155000   4749 Pleasantview Road   Harbor Springs   S   2   2   0   One         Hartwick, Bob   Coldwell Banker Schmidt   

With a bunch of extra text following that I've trimmed off for our purposes here. See the 'S' after the town? I've created the following code to look for the 's' in relation to the word order.

Code: [Select]
<?php
// Listings file
$listings= file('listingsTest.txt');
$i = 0;
$j = 0;
$_ENV['a'] = 0;

foreach($listings as  $value) {
//Replace all spaces of every kinds with single spaces
$listings[$i] = preg_replace("'\s+'", ' ', $listings[$i]);
//Put all characters into an array corisopndings to each line in $listings
$_ENV['chars'.$i] = preg_split('//', $listings[$i]);

//Place all words and uninterupted numbers and place in array $words
$_ENV['words'.$i] = preg_split('/ /', $listings[$i]); 

$i++;
}

//echo $_ENV['chars'.'1']['1'];

foreach($_ENV['words'.$_ENV['a']] as $char){
$countedf = preg_split('//', $_ENV['words'.$_ENV['a']][$j]);
$counted = count($countedf) - 2;

$wordBeforef = preg_split('//', $_ENV['words'.$_ENV['a']][$j-1]);
$wordBefore = count($wordBeforef) - 2;

$wordAfterf = preg_split('//', $_ENV['words'.$_ENV['a']][$j+1]);
$wordAfter = count($wordAfterf) - 2;

if( ($counted == 1) 
&& ($wordAfter == 1)
&& (is_numeric($_ENV['words'.$_ENV['a']][$j+1]))
//&& ($wordBefore == 1)
//&& (!is_numeric($_ENV['words'.$_ENV['a']][$j]))
//&& (is_numeric($_ENV['words'.$_ENV['a']][$j+2]))
//&& ($_ENV['words'.$_ENV['a']][$j+3] == ' ' )
){
echo '*';
echo $_ENV['words'.$_ENV['a']][$j];
echo '*';
$_ENV['a']++;
$j =0;
//$j=1
}
//echo $_ENV['chars'.$_ENV['a']][$j];

$j++;
}

?>

As you can see from the if then statements, I've gotten to the point where It's replying to the 'S' at the end of the address thus telling me where the address ends. I am however having  a problem I believe is a server issue. The code works fine when applied to 12 lines like the ones above, when I apply it to more of those lines it does not return the 'S' for them even if I used the exact same line more than 12 times. The main file which I'd like to automate the parsing of has thousands of these such lines in it.  If I try to apply this code to the file with these thousands of lines, the browser returns a "The website encountered an error while retrieving http://localhost. It may be down for maintenance or configured incorrectly".

I take this to mean the server is doing too much work for it to be completed. I think when it reaches it's twelfth, the temporary memory of my program/server or some thing else, is exhausted. I'm applying these if then statements to every single word in the file. Is this a processing issue on the server? I was applying this code to every character in the file and thought I could fix the problem by applying instead to every word given there are less words than characters. I have the processing time on the server set to 10000 and it's not taking along time to return the error message.

I would be very grateful to any help any of you could provide. Thank you for your time.

I am currently working on an application to schedule conferences.  I have everything completed to create a conference including start time and duration.  The problem I have now though is how do I monitor MySQL for the conferences that are created and perform actions when the duration of the conference is up? I was looking into MySQL events but those seem to be only internal events and are not able to execute anything outside of that. I was thinking about a infinite loop that queries MySQL and sleeps for one second but thought that this might be a lot of load on the server. Any thoughts I really appreciate it.

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 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 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?

does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

Code: [Select]

Hi. I have some code which needs to return a single variable from the function and stored as a variable within this page, so it can be echoed later on in the page. I couldn't get it to return as a variable, so i used "return compact();" to return the variable and "extract (myFunction());" to extract it to variables. However, when I turned on php's display errors and error reporting function, I got an error message saying "Warning: extract() [function.extract]: First argument should be an array in /my/web/site/index.php on line 6" (which is where my extract function is). This works fine with passing more than one variables through, is there another way pass one variable from a function to be stored as a variable on the page which called the function?

Here is the function:
Code: [Select]
<?php
//This is a list of numeric error codes against their text. this will return the error code as the variable $issue
function checkLoginIssue() {

//If there is an error code
if (isset($_GET["issue"])) {
 
  //cycle through the list until the code is reached, return the text and break the switch
    switch ($_GET["issue"]) {

      case "1":
              $issue = '<p class="warning">Please log in to view this page</p>';
              break;
  
      case "2":
              $issue = '<p class="warning">Wrong Username or Password</p>';
              break;

        case "3":
              $issue = '<p class="warning">No user found with those details</p>';
              break;

    }
 
 //return the variable in an array with a single value
 return compact('issue');
 
}
 
}
?>
And here is the code which calls the function:
Code: [Select]
<?php
extract(checkLoginIssue());
?>

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(

"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

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

Hello,

I have 2 array questions that I'm hoping someone can help me with.

1) First, I'm trying to add elements to a previously existing array.  I start with:

$data = array('text' => $_POST['text'],

   'question_type' => $_POST['question_type'],

  'solution' => $_POST['solution'],

  'filename' => $filename,

   'author_id' => $_POST['author']);
Then, under certain circumstances, I'm going to want to add the following to the array $data:

      'incorrect_solution1' => $_POST['incorrect_solution1'],

'incorrect_solution2' => $_POST['incorrect_solution2'],

'incorrect_solution3' => $_POST['incorrect_solution3'])

I tried the concatenation function, combined with an if statement but then PHP thinks that I have a string.

2) Once I have the array, I want to shuffle the solution and 3 incorrect solution indices.  I'm not sure how to shuffle just a portion of an array.

Any help with either or both questions would be appreciated.

Thank you.

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.

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!

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"]=>

        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!
