Getting values from associative array - php

Question

I have the following main array called $m
Array
(
[0] => Array
(
[home] => Home
)
[1] => Array
(
[contact_us] => Contact Us
)
[2] => Array
(
[about_us] => About Us
)
[3] => Array
(
[feedback_form] => Feedback Form
)
[4] => Array
(
[enquiry_form] => Products
)
[5] => Array
(
[gallery] => Gallery
)
)
I have the values eg home, contact_us in a array stored $options , I need to get the values from the main array called $m using the $options array
eg. If the $options array has value home, i need to get the value Home from the main array ($m)
my code looks as follows
$c = 0;
foreach($options as $o){
echo $m[$c][$o];
++$c;
}
I somehow just can't receive the values from the main array?

Answer 1

I'd first transform $m to a simpler array with only one level:
$new_m = array();
foreach ($m as $item) {
foreach ($item as $key => $value) {
$new_m[$key] = $value;
}
}
Then you can use:
foreach ($options as $o) {
echo $new_m[$o];
}

Answer 2

Try this:
foreach($options as $o){
foreach($m as $check){
if(isset($check[$o])) echo $check[$o];
}
}
Although It would be better TO have the array filled with the only the pages and not a multidimensional array

Answer 3

Assuming keys in the sub arrays are unique you can
merge all sub arrays into a single array using call_user_func_array on array_merge
swap keys and values of your option array
Use array_intersect_key to retrieve an array with all the values.
Example like so:
$options = array('about_us', 'enquiry_form');
$values = array_intersect_key(
call_user_func_array('array_merge', $m), // Merge all subarrays
array_flip($options) // Make values in options keys
);
print_r($values);
which results in:
Array
(
[about_us] => About Us
[enquiry_form] => Products
)

Answer 4

How's this?
foreach( $options as $option )
{
foreach( $m as $m_key => $m_value )
{
if( $option == $m_key )
{
echo 'Name for ' . $options . ' is ' . $m_value;
break;
}
}
}

Answer 5

Try using a recursive array_walk function, for example
$a = array(
array('ooo'=>'yeah'),
array('bbb'=>'man')
);
function get_array_values($item, $key){
if(!is_numeric($key)){
echo "$item\n";
}
}
array_walk_recursive($a,'get_array_values');

Answer 6

Are you sure that the options array is in the same order of $m? Maybe you your
echo $m[$c][$o];
is resolving into a $m[0]['gallery'] which is obviously empty.
you can try different solutions, to me, a nice one (maybe not so efficient) should be like this:
for($c=0, $limit=count($c); $c < $limit; $c++)
if (array_search(key($m[$c]), $options))
echo current($m[$c]);
If you would like to use your approach have to flatten your array with something like this:
foreach ($m as $o)
$flattenedArray[key($o)]=current($o);
foreach ($options as $o)
echo $flattenedArray($o);
Doing this, though, eliminates duplicate voices of your original array if there are such duplicates.

Answer 7

$trails1 = array();
foreach ($trails as $item) {
foreach ($item as $key => $value) {
$trails1[].= $value;
}
}
echo '<pre>';print_r($trails1);
exit;
