Question

I have a multi-dimensional array consisting of (a) description, (b) the minimum number of years and (c) the maximum number of years:

$years_array = array( 
 array("Any", 0, 255),
 array("New", 0, 1),
 array("5 - 10yrs", 5, 10),
 array("10 - 20yrs", 10, 20)
);

Given both the minimum $min and maximum $max number of years, how do I match it to give the description $description in the array?

Example:

$min = 5, $max = 10 => $description = "5 - 10yrs";

Answer 1

Quick, dirty and just for showing a possibility…

<?php
$years_array = array( 
 array("Any", 0, 255),
 array("New", 0, 1),
 array("5 - 10yrs", 5, 10),
 array("10 - 20yrs", 10, 20)
);

function getYearDescription(&$years, $min, $max) {
 foreach($years as $year) {
  if($year[1] == $min && $year[2] == $max) {
    return $year[0];
  }
 }

 return "n/a";
}

echo(getYearDescription($years_array, 5, 10));
?>

I suppose you need an exact match
