PHP array and select list
提问by Sergio
I want to use php array for HTML select list. In this case it will be the list of countries but beside of country name that is listed in drop down list I need as a value of each country short country code.
我想将 php 数组用于 HTML 选择列表。在这种情况下，它将是国家/地区列表，但在下拉列表中列出的国家/地区名称旁边我需要作为每个国家/地区短国家/地区代码的值。
The php array that I'm currently using looks like:
我目前使用的 php 数组如下所示：
$wcr=array(
'Angola',
'Antigua & Barbuda',
'Armenia',
'Austria',
'Azerbaijan',
.....
);
The PHP page that using this array:
使用此数组的 PHP 页面：
<select name="country"><option selected value=""> ---------
<? $p=1;asort($wcr);reset($wcr);
while (list ($p, $val) = each ($wcr)) {
echo '<option value="'.$p.'">'.$val;
} ?>
</select>
The value should be short country code (something like 'ES', 'US', 'AN', ...) instead of numbers that I have right now as a values in this form. That short country codes I will write in this same PHP array somewhere, if it's possible.
该值应该是简短的国家/地区代码（类似于“ES”、“US”、“AN”等），而不是我现在在这种形式中作为值使用的数字。如果可能的话，我将在同一个 PHP 数组中的某个地方编写那个简短的国家/地区代码。
How can I do that?
我怎样才能做到这一点？

Use foreach(), it's the best function to loop through arrays
使用foreach()，循环数组是最好的函数
your array should look like jakenoble posted
你的数组应该看起来像 jakenoble 发布的
<select name="country">
<option value="">-----------------</option>
<?php
foreach($wcr as $key => $value):
echo '<option value="'.$key.'">'.$value.'</option>'; //close your tags!!
endforeach;
?>
</select>
I also made some minor adjustements to your html code. The first option in the list will be selected by default so no need to specify it ;)
我还对您的 html 代码进行了一些小调整。默认情况下将选择列表中的第一个选项，因此无需指定;)
EDIT: I made some edits after reading your question again

First make an associated array of country codes like so:
首先制作一个相关的国家代码数组，如下所示：
$countries = array(
'gb' => 'Great Britain',
'us' => 'United States',
...);
Then do this:
然后这样做：
$options = '';
foreach($countries as $code => $name) {
$options .= "<option value=\"$code\">$name</option>\n";
}
$select = "<select name=\"country\">\n$options\n</select>";

Do you mean like this:
你的意思是这样吗：
$wcr=array(
"ANG" = > 'Angola',
"ANB" = > 'Antigua & Barbuda',
"ARM" = > 'Armenia',
"AUS" = > 'Austria',
"AZB" = > 'Azerbaijan'
);
Then in your while loop, $pis your Short code.
然后在你的 while 循环中，$p是你的短代码。
Improved version of Krike's loop, if using my array of short codes as array keys:
Krike 循环的改进版本，如果使用我的短代码数组作为数组键：
<select name="country">
<option value="">-----------------</option>
<?php
asort($wcr);
reset($wcr);
foreach($wcr as $p => $w):
echo '<option value="'.$p.'">'.$w.'</option>'; //close your tags!!
endforeach;
?>
</select>

If you are using this sort of array as shown by jakenoble I would use foreach().
如果您使用 jakenoble 所示的这种数组，我将使用 foreach()。
$wcr=array(
"ANG" = > 'Angola',
"ANB" = > 'Antigua & Barbuda',
"ARM" = > 'Armenia',
"AUS" = > 'Austria',
"AZB" = > 'Azerbaijan'
);
So the Foreach would look something like:
所以 Foreach 看起来像：
foreach($wcr as $short_code => $descriptive) {
?>
<option value="<?php echo $short_code; ?>"><?php echo $descriptive; ?></option>
<?php
}
