recursive function

["Manuel Pérez López" <mapelo@xxxxxxxxx>]

Hello everyone:

Is it possible to do recursive this function?

I can write it so linear. But only a  finite number of loops.
Thanks.

This is:


function ($field, $arr_secuence_reverse)
{


	if (count($arr_secuence_reverse) == 1)
	{
		return getPrimaryKey4Field($field,$arr_secuence_reverse[0],NULL);
	}

	if (count($arr_secuence_reverse) == 2)
	{
	   	$sel2 = select($arr_secuence_reverse[0],"pk as
pk_current",NULL,$arr_secuence_reverse[1],"pk as pk_next",NULL);
	   	foreach ($sel2 as $n2=>$v2)
		{
		    $res[$v2['pk_current']] =
getPrimaryKey4Field($field,$arr_secuence_reverse[1],'fk_'.$arr_secuence_reverse[0]."='".$v2['pk_current']."'");
		}
	}

	if (count($arr_secuence_reverse) == 3)
	{
	   	$sel3 = select($arr_secuence_reverse[0],"pk as
pk_current",NULL,$arr_secuence_reverse[1],"pk as pk_next",NULL);
	   	foreach ($sel3 as $n3=>$v3)
		{
		    $res[ $v3['pk_current'] ][ $v3['pk_next'] ] =
getPrimaryKey4Field($field,$arr_secuence_reverse[2],'fk_'.$arr_secuence_reverse[1]."='".$v3['pk_next']."'");
		}
	}

	if (count($arr_secuence_reverse) == 4)
	{
	   	$sel4 = select($arr_secuence_reverse[0],"pk as
pk_current",NULL,$arr_secuence_reverse[1],"pk as pk_next",NULL);
	   	foreach ($sel4 as $n4=>$v4)
		{
	   		$sel5 = select($arr_secuence_reverse[1],"pk as
pk_current",NULL,$arr_secuence_reverse[2],"pk as pk_next",NULL);
	   		foreach ($sel5 as $n5=>$v5)
			{
		    	   $res[ $v4['pk_current'] ][ $v4['pk_next'] ][
$v5['pk_current'] ] =
getPrimaryKey4Field($field,$arr_secuence_reverse[3],'fk_'.$arr_secuence_reverse[2]."='".$v5['pk_current']."'");
			}
		}
	}

	if (count($arr_secuence_reverse) == 5)
	{
	   	$sel5 = select($arr_secuence_reverse[0],"pk as
pk_current",NULL,$arr_secuence_reverse[1],"pk as pk_next",NULL);
	   	foreach ($sel5 as $n5=>$v5)
		{
	   		$sel6 = select($arr_secuence_reverse[1],"pk as
pk_current",NULL,$arr_secuence_reverse[2],"pk as pk_next",NULL);
	   		foreach ($sel6 as $n6=>$v6)
			{
		    	   $res[ $v5['pk_current'] ][ $v5['pk_next'] ][
$v6['pk_current'] ][ $v6['pk_next'] ] =
getPrimaryKey4Field($field,$arr_secuence_reverse[4],'fk_'.$arr_secuence_reverse[3]."='".$v6['pk_next']."'");
			}
		}
	}

}
