Question

我有一个多维数组，包括（a）描述，（b）最小年数和（c）最大年数：

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

同时给出最小$min和最长$max年数，如何匹配它以在数组中提供描述$description？

示例：

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

Answer 1

尝试这样的事情：

function getDescription($min,$max) 
{
  // source
  $years_array = array( 
    array("Any", 0, 255),
    array("New", 0, 1),
    array("5 - 10yrs", 5, 10),
    array("10 - 20yrs", 10, 20)
  );
  foreach ($years_array as $yearRecord) {
    if ($min == $yearRecord[1] && $max == $yearRecord[2])) {
      return $yearRecord[0];
    }
  }
  return false;
}

getDescription(0, 255); // == "Any"

Answer 2

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

Answer 3

快速，肮脏，只是为了展示一种可能性......

<?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));
?>

我想你需要完全匹配
