PHP 5.3 从数组中读取最长的字符串 [英] Read the longest string from an array in PHP 5.3

问题描述

这是代码的一部分.

$DatabaseArray=Array("Cooking","look","I cant","Walking the dog to the park","washing","talk","one");
  
$largest = max($DatabaseArray);
  
echo $largest. "<br />";

我想从 PHP 5.3.0 中的数组中读取最长的字符串.我已经尝试了 max 函数，但似乎没有按预期工作.

I would like to read the longest string from an array in PHP 5.3.0. I've tried the max function but doesnt seem to work as expected.

推荐答案

$lengths = array_map('strlen', $DatabaseArray);
$maxLength = max($lengths);
$index = array_search($maxLength, $lengths);
echo $DatabaseArray[$index];
