Foreach回显出数组php中的元素名称[关闭]

问题描述：

I have a PHP array, that look like this

$melee = array(  
    "ct-knife" => "link",  
    "t-knife" => "link",  
    "zeus" => "link"  
);

foreach ($pistol as $value){
    echo '<option value="'.$value.'">"'.$value.'"</option>';
}

and I want my "Foreach" to print out the names of the links, but it prints out the links. Does anyone know how to fix this?

Thanks in advance

For associative arrays alter your foreach to use the keys. The following will get you what you want.

$melee = array(  
    "ct-knife" => "link",  
    "t-knife" => "link",  
    "zeus" => "link"  
);

foreach ($pistol as $key => $value){
    echo '<option value="'.$key.'">"'.$key.'"</option>';
}

This is another way :

<?php
/**
* Created by PhpStorm.
* User: jokuf
* Date: 7/19/15
* Time: 8:34 PM
*/
$melee = array(
"ct-knife" => "link",
"t-knife" => "link",
"zeus" => "link"
);

function selectWeapon($melee){
$i = 0;
echo '<select>';


while ($i < count($melee)) {
    foreach ($melee AS $key => $value) {
        echo '<option>' . $key . '</option>';
        $i++;
    }
}
echo '</select>';
}

selectWeapon($melee);
