在这里,我的问题是,我正在成为AS,EU,NA,SA等大陆
我需要将AS更改为亚洲,欧盟更改为欧洲,NA更改为北美,SA更改为南美洲。如何使用if else
条件?
答案 0 :(得分:2)
试试这个 -
switch ($continent1) {
case "AS":
$continent1 = 'Asia';
break;
case "EU":
$continent1 = 'Europe';
break;
case "NA":
$continent1 = 'North America';
break;
default:
$continent1 = '';
}

在数据库中没有这个,你可以试试这个:
$arr_continent = array('AS'=>'Asia','EU'=>'Europe','NA'=>'North America','SA'=>'South America');
echo "Continent: " .$arr_continent[$continent1]. "<br />";
它比switch语句更整洁! ;)

switch ($continent)
{
case "AS":
$continent1 = 'Asia';
break;
case "EU":
$continent1 = 'Europe';
break;
case "NA":
$continent1 = 'North America';
break;
// rest of codes
}

您可以创建一个功能而无需使用 if / else 或切换语句
<?php
function get_continent($continent_name){
$arr = array(
"AS" => 'Asia',
"EU" => 'Europe',
"NA" => 'North America',
"SA" => 'South America'
// and define more keys and value pair of continent short and full name
);
return ($arr[$continent_name]!="") ? $arr[$continent_name] : "N/A" ;
}
echo get_continent("EU");
// output - Europe
?>
如果您需要一次又一次地执行类似任务,此代码还将提高重用能力
答案 4 :(得分:0)
您可以使用$continent1
变量上的switch方法将值替换为您想要的值
switch($continent1)
{
case 'AS':
echo "Continent: Asia";
break;
case 'EU':
echo "Continent: Europe";
break;
case 'NA':
echo "Continent: North America";
break;
case 'SA':
echo "South America";
break;
default:
echo "nothing matched"
break;
}
