PHP - Echo Multidimentional Arrays

OK, have no idea what's going on... I've done this a million times... why wont this output!??
I must have a major brain meltdown and dont know it yet!!!

Code: [Select]
<?php

// this echoes just fine:
echo $_POST['testfield'];


// but this wont echo:
echo 
if (isset($_POST['testfield']))
{
$_POST['testfield'] = $test;
}
echo $test;


/// or even this DOESNT echo either!:
$_POST['testfield'] = $test;
echo $test;

?>

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?

Hi All,

I'm trying to echo the response from an SLA query, the query works and returns the data when I test it on an SQL application.. but when I run it on my webpage it won't echo the result.

Please help?

<?php   
$mysqli = mysqli_connect("removed", "removed", "removed", "removed");  
$sql = "SELECT posts.message FROM posts INNER JOIN threads ON posts.pid=threads.firstpost WHERE threads.firstpost='1'";  
$result = mysqli_query($mysqli, $sql);   
echo {$result['message']}; 
?>

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 have a log system that allows 10 logs on each side(Left and right). I am trying to make it so that the left side has the 10 most recent logs, then the right as the next 10. Any ideas?

So I need to echo a row from my database with php, but where i need to echo is already inside an echo. This is my part of my code:


$con = mysql_connect("$host","$username","$password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("main", $con);

$result = mysql_query("SELECT * FROM Vendor");

while($row = mysql_fetch_array($result))
  {
//I need to echo right here  .................. but I get a blank page when I try this. Please Help.
  echo '<option value=$row['vendor_id']>'; echo $row['vendor_id']; echo '</option>';
  }

mysql_close($con);

Result: A Blank page.
Thanks in advance!

Hi   I try to echo out random lines of a html file and want after submit password to whole content of the same html file. I have two Problems. 1st Problem When I echo out the random lines of the html file I don't get just the text but the code of the html file as well. I don't want that. I just want the text. How to do that?

for($x = 1;$x<=40;$x++) {
		$lines = file("$filename.html");
        echo $lines[rand(0, count($lines)-1)]."<br>";
        }

I tried instead of "file("$filename.html");" "readfile("$filename.html");" But then I get the random lines plus the whole content. Is there anything else I can use instead of file so that I get the random lines of text  without the html code?P.S file_get_contents doesn't work either have tried that one.     2nd Problem:   As you could see in my first problem I have a file called $filename.html. After I submit the value of a password I want the whole content. But it is like the program did forget what $filename.html is. How can I make the program remember what $filename.html is? Or with other words how to get the whole content of the html file?   My code:

if($_POST['submitPasswordIT']){
if ($_POST['passIT']== $password ){
$my_file = file_get_contents("$filename.html");
echo $my_file;
}
else{
echo "You entered wrong password";
}
}

If the password isn't correct I get: You entered wrong password. If the password is correct I get nothing. I probably need to create a path to the file "$filename.html", but I don't know exactly how to do that.   

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.

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.

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.

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; 
?>

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

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
