please what i am missing.
thanks for any guidance .

This is PHP 101, but I'm struggling to see the obvious.  I have the query below which brings back a list of quizids.   I put them into an array using mysql_fetch_array. I then want to check to see if a certain quizid is actually in the quizzes table, so I thought I could simply us in_array.  But it's only checking the first quizid.  That doesn't make sense to me. Isn't mysql_fetch_array creating an array with all values automatically? 

If I actually have to use a "while" loop or something, can someone help me with how to write that code most efficiently.

Code: [Select]
$query = "SELECT quizid FROM quizzes";
$getquizids = mysql_query($query, $connection);
if (!$getquizids) {
die("Database query failed: " . mysql_error());
} else {
$allquizids=mysql_fetch_array($getquizids);
                    if (in_array($_GET['quizid'], $allquizids)) {
//continue since quiz exists
} else {
redirect_to('index.php');
}
 }

I can't seem to understand why in_array is NOT finding the 'needle'.

php file:
Code: [Select]
<?PHP
$search = "WS11";
$valid_codes = file("outcode2.txt");
if(in_array($search, $valid_codes)){
echo "yes";
}else{
echo "No";
}
echo $search . "<hr>";
echo "<PRE>";
print_r($valid_codes);
echo "</pre>";
?>

outcode2.txt:
Code: [Select]
WS10
WS11
WS12
WS13
WS14
WS15

WS11 is in the outcode2.txt
It is not an issue of case.
Perhaps my old eyes just keep missing the problem.
Any help is appreciated.

I know this works and that's why I'm puzzled. I'm bringing in data from a textarea and trying to compare it.

index.php
Code: [Select]
<form name"fruit-farm" action="fruit-check.php" method="POST">
<textarea name="fruit-list">
Apples
Bananas
Oranges
Pickles
Hamburgers
Grapes
</textarea>
<input type"submit" name="submit" value="Check The Fruit">
</form>

fruit-check.php
Code: [Select]
if (isset($_POST['submit'])) {

//Bring in the data
$fruit-list = explode("\n", $_POST['fruit-list']);

//Search for Hamburgers
$hamburgers = "Hamburgers";

 if (in_array($hamburgers,$fruit-list)){
echo "That is not a fruit";
 }

}

What's puzzling me is that it's not working. It must be something blantently obvious. It has something to do with the '$fruit-list' array and how it is being brought into the form. It posts fine. The reason I think this is the case is because if I simply create an array that is identical to the form coming in it works:

Code: [Select]
if (isset($_POST['Submit'])) {

//Bring in the data
$fruit-list = explode("\n", $_POST['fruit-list']);

//Search for Hamburgers
$hamburders = "Hamburgers";

$fruit-list = array('Apples', 'Bananas', 'Oranges', 'Pickles', 'Hamburgers', 'Grapes);

 if (in_array($hamburders,$fruit-list)){
echo "That is not a fruit";
 }

}

When I 'print_r' both arrays they both look identical. What is wrong and/or different with the way I'm bringing in the textarea that's causing this not to work?

Hi folks!

I have two arrays:

1) print_r($users1); 
Array ( => 1 [1] => 2609 [2] => 2612 [3] => 2620 [4] => 2621 [5] => 2624 [6] => 2627 [7] => 2629 )

2) print_r($users2); 
Array ( => 1 [1] => 2609 [2] => 2610 [3] => 2611 [4] => 2612 [5] => 2617 [6] => 2618 [7] => 2619 [8] => 2620 [9] => 2621 [10] => 2624 [11] => 2625 [12] => 2626 [13] => 2627 [14] => 2628 [15] => 2629 )

now why does nothing return when I use in_array?

if(in_array($users1,$users2)) 
  return true;

all values in $users1 is in $users2...

Please help, need help fast!

Thank you

Hello:

I'm trying to compare two mySQL result sets (for determining when to check a checkbox in an input form).

$dataList['listname'] is my needle. (only the checkboxes I want to check)
$data['listname'] is my haystack (the list of all checkboxes)


Code: [Select]
while($dataList = mysql_fetch_array($runListQuery))
{
$checked = '';
echo $data['listname'].'<br /><br />';
echo $dataList['listname'].' :: ' .  $data['listname'] . '::' . (string)array_search ($dataList['listname'],$data['listname'],false) .'<br>';
echo in_array($dataList['listname'],$data['listname']);
echo '<br>----------------------<br>';
var_dump($data['listname']);
echo '<br>----------------------<br>';
var_dump ($dataList['listname']);
echo '<br>----------------------<br>';
if(in_array($dataList['listname'],$data['listname'],false)) {
echo 'found!!!!!!!!!!!';
$checked = 'CHECKED';
}
echo '<tr>';
echo '<td>' . $dataList['listname'] . '</td>';
echo '<td><input type="checkbox" '. $checked . ' name="'.$dataList['listname'].'" />';
echo '</tr>';
}
I never hit the 'found!!!!!!!!' string.  My output is below:

Code: [Select]
list-charter

halwasiya :: list-charter::

----------------------
string(12) "list-charter"
----------------------
string(9) "halwasiya"
----------------------
list-charter

halwits :: list-charter::

----------------------
string(12) "list-charter"
----------------------
string(7) "halwits"
----------------------
list-charter

list-charter :: list-charter::

----------------------
string(12) "list-charter"
----------------------
string(12) "list-charter"

Code: [Select]
$colorarray = isset($_POST['form']['color']) ? intval($_POST['form']['color']) : 0;

$color = array(
"1",
"2",
"3",
"4",
"5",
"6",
"7",
"8",
"8",
"9",
"10",
"11",
"12",

"15",
"16"
);
if (in_array($color, $colorarray)) {
    echo "search found";
exit;
}else{
echo "hacker";
exit;
}
i submit  my $_POST['form']['color'] as 1 through 16 and it always says hacker? 

I am trying to pull the username for everyone who appears within an array. How would i go about this?

something like this maybe?

SELECT * FROM users WHERE username (in_array($users))

I have a section in one of my scripts that checks for a value in array and the value doesn't exist in the array then it add it.  This works fine for single array but not for mulit-dimensional arrays.  Has anyone had a similar problem and knows a good solution?

Code: [Select]
if(in_array($words[$i], $searchWords)){
    //Do nothing
}else{
    $searchWords[] = $words[$i];
}

Hello,

I've been curious why the following won't work. Could anyone show me what I am doing wrong. The code is to find the TLD in a URL.

Code: [Select]
$a[] = parse_url( 'www.example.com' );
$tld_arr = array ( 'com', 'net', etc...);


for ($i=0; $i<count($this->a); $i++)
{
      if (in_array ( $this->a[$i]['host'], $tld_arr) ) < This is what I'm curious about
     {
            //do something
     }
// do something else
}


Thank you

I have the following simple code to test against collision on a primary key I am creating:

Code: [Select]
        $machine_ids = array();
for($i = 0; $i < 100000; $i++) {
//Generate machine id returns a 15 character alphanumeric string
                $mid = Functions::generate_machine_id();

if(in_array($mid, $machine_ids)) {
die("Collision!");
} else {
$machine_ids[] = $mid;
}
}

die("Success!");

Any idea why this is taking minutes to run? Anyway to speed it up?

Hey guys,

)

Can someone please help me figure this out:

I have a normal text file with 3 lines in it, every line contain one date i.e 12112011 (12.11-2011). I put the content of that file in an array, and want to compair the dates in the text file against the date generated from the loop. Problem is, i can only get a match for the last date listed in the text file no matter what.. If i have 4 dates in the file, it only style the last date.

Thanks!

--- CODE SNIPPET ---

$day_num = 1;
$days_in_month = 30;
$month = 11;
$year = 2011;

//Access the file containing already taken dates and load them in an array:
$date_array = file("test.txt");

//count up the days, untill we've done all of them in the month and check them against the dates in the text file:
while ($day_num <= $days_in_month) {

   // Set the variable $date to be checked against the content of the array:
   $date = $day_num . $month . $year;
   
   if (in_array($date, $date_array)) {
               echo "<td class='color_green'>$day_num</td>";
      //print_r($date_array);
   }
   else {
      echo "<td>$day_num</td><br />";
   }
   
   $day_num++;
}

Hi There, I have the following code:
two arrays:
$user_body_group & $DB_Seconday_muscles

I want to look up the "$DB_Seconday_muscles" Array and search for the elements in the "$user_body_group" array

The result would be displaying a checkbox list with only the items in the "$user_body_group" array checked:


foreach($DB_Seconday_muscles as $value) {
   

      echo "<input name=\"colors[]\" type=\"checkbox\" value=\"$value\"";
      
         if (in_array($value,$user_body_group))
         {
         echo "CHECKED";
         }
      
      
      echo "> $value ";

}

BUT... When i run thi script i only get the first element in the searched array ticked.

Can anyone help!

Many Thanks!

Okay, this is my loop to show the birthday for Years.
Code: [Select]
<?php
    for ($i=2006; $i>=1900; $i=$i-1)
    {
     echo "<option value='$i'>$i</option>";
    }
   ?>
It will show 2012 to 1900 as a dropdown menu.. in my select form.


Now I want to check the user input against this loop.

The form is:

Code: [Select]
<select name="BirthDay[]">
   <?php
    for ($i=2012; $i>=1900; $i=$i-1)
    {
     echo "<option value='$i'>$i</option>";
    }
   ?>
   </select>
Now, I want to use in_array function to check if it equals any of the values I looped, if it doesn't echo out "Hacker!"


Here is my in_array




Code: [Select]
$bday = array( NEED TO PUT THIS LOOP HERE SOMEHOW?!?!
);
if (!in_array($_POST['BirthDay'], $bday)) {
message("Please select a Correct Birthday, or u trying to hack");
}

Thanks if u can help!
