correct order of array help

[canabatz]

hi all ,i want to build something like that:

 

$try[] = array( "1", "2", "3");

$try[] = array( "A", "B", "C");

 

then i want to shffle the first array , so it can be 1,2,3 or ,3,1,2 or 2,1,3 ,any combination possible.

 

then i want to have a form so i can submit the result like that

 

if i see the first array is 1,3,2 then i need to type in my input field  ACB

 

and the answer i get is correct ,if the my input is wrong then i get wrong answer .

 

so :

 

1,2,3 = a,b,c

3,1,2 = c,a,b

2,3,1 = b,c,1

 

one more thing , a is not equal to 1 ,a is equal to the possition of 1 ,so it can be 1,2,3 for the first array and g,w,r for the second array!

 

 

my quastion is how im doing something like that , how im tellin the first array that 1 is equal to the position of a and 2 is equal to the position of b .....

and do it in the right way.

 

thanx

Simpler to have 1 array rather than a multi-dimensional array i.e

<?php	
$array = range('A','C');
$keys  = array_keys($array);
shuffle($keys);
// display the shuffled array keys
print_r($keys);

// use the keys to restore the string
for($x = 0; $x < count($keys); $x++) {
print $array[$keys[$x]];
}
?>

Part 1: PHP has a built in shuffle method for arrays: http://php.net/manual/en/function.shuffle.php

 

Part 2: You can extract data from an array using a number:  $my_array[4] would return the 5th element in the array.

thanks bowett ,i didnt know that i can get the array like that

 

how im doing that :

 

if the array is like that:

 

array( 1,2,3,4,2,1,4,6,4,2,1,3)

 

can i print the position of number one?

 

so the output will be

array 0 , 5, 10 - this is the position of 1 in the array!

 

thanx

Take a look at array_keys.

All the functions mentioned above are used in my original example

[canabatz]

what is the way i need to do it?

 

i want to have my array like this

 

$array[] = array (1,2,3,4)

 

$array[] = array (a,b,k,g)

 

i want to have a form to ask me to input the result in order

the first array will be in shuffle on every refresh of the page!

 

so if i enter my page

 

and the display will show me 2,1,4,3

then i need to type in the form field  b,a,g,k

 

and when i press on submit ,i get back answer if my input was correct!

if didnt input it in the right order ,then i get nagative answer!

 

thanx

why do you have two arrays won't the keys of array2 will be same as the values as array1 ?

[canabatz]

im using shuffle($array) on the first array.

[rajivgonsalves]

why just not do it on the second array ? what connection do they both have ?

[canabatz]

$array[] = array (1,2,3,4) <==== shuffled

 

$array[] = array (a,b,k,g)

 

 

im entering the page and i get this sequence

 

2,1,4,3

 

and i get a question ,what is equal to 1,3

 

my answer needs to be b,g

 

i need it in a form !

 

thanks

[rajivgonsalves]

I hope I got you right this is what I came up with

 

<?php
$array1 = array(2,1,4,3);

$array2 = array('a','b','c','g');

$array3 = array();

foreach ($array1 as $key) {
    array_push($array3,$array2[$key-1]);
}

print_r($array3);
?>
