Array fusion question

[asantos]

Hi.
I need to get an array that holds the values 10,11,12 from this other array. How can i achieve that?

Array
(
[0] => Array
 (
  [0] => 10
  [1] => 1
  [2] => Fútbol
  [3] => futbol
  [4] => 0
 )
[1] => Array
 (
  [0] => 11
  [1] => 1
  [2] => Tenis
  [3] => tenis
  [4] => 0
 )
[2] => Array
 (
  [0] => 12
  [1] => 1
  [2] => Artes marciales
  [3] => artes-marciales
  [4] => 0
 )
)

Hi!

Do you need a function that saves the first item of each array, and then return it, right?

For the first item, what array combination should be saved, (only value) or (key => value)?

Loop through and grab the first value of each array.

$array = array(); // initialize 
foreach ($array1 as $array2) { 
 $array[] = $array2[0]; 
 continue [php.net]; 
} 
print_r($array);

// 
// @array_first_key($ary, $pos) 
// $ary - The source array 
// $pos - key position that you want to return 
// 
function array_first_key($ary, $pos = 1)  
{  
$ret = array();  
foreach ($ary as $ary2)  
{  
$ret[] = $ary2[$pos - 1];  
}  
return $ret; 
}

coopster, is that "continue" really necessary?

[coopster]

No, it is not. Originally I was filling the new array a bit differently but made it more efficient by grabbing the zero index that you were after instead. You can get rid of it now.

[orion_rus]

for ($i=0;$i<count($array);$i++)
{
if (in_array(array(10,11,12),$array[$i]))
{echo "In array";}
}
