为每个数组元素PHP赋值

Say you have an array like this...

假设你有一个这样的数组……

username, password, email

and you need to assign a value to each element. After, this needs to be formatted into a string like this:

你需要给每个元素分配一个值。之后，需要将其格式化为如下字符串:

username=someRandomValueAssigned&password=someRandomValueAssigned&email=someRandomValueAssigned

how would I do this? Thanks.

我该怎么做呢?谢谢。

4 个解决方案

#1

$keys = array('username', 'password', 'email');

$values = array('someusername', 'somepassword', 'someemail');

$data = array_combine($keys, $values);

array_combine will return an associative array like,

array_combine会返回一个关联数组，

$data = array( 
          'username' => 'someusername',
          'password' => 'somepassword',
          'email' => 'someemail'
        );

then the result you want can be achieved using a simple foreach loop

然后可以使用一个简单的foreach循环来实现所需的结果

$str = '';

foreach($data as $k=>$v) {
   $str .= $k > 0 ? '&' : '';
   $str .= $k . '=' . $v ;
}

echo $str;

Also, I suspect you are trying to build a url so you might want to check out php's http_build_query function

另外，我怀疑您正在尝试构建一个url，以便您可能希望检查php的http_build_query函数

#2

$array_value=array();
$array_value['username']=somevalue;
$array_value['password']=somevalue;
$array_value['email']=somevalue;
$array_str=array();
foreach($array_value as $key=>$value){
   array_push($array_str,$key."=".$array_value[$value]);
}
$array_str=join("&",$array_str);
echo $array_str;

#3

Looks like you're building a query string, I think you want to use http_build_query():

看起来您正在构建一个查询字符串，我认为您希望使用http_build_query():

$data = array(
    'username'  =>  'someRandomValueAssigned',
    'password'  =>  'someRandomValueAssigned',
    'email'     =>  'someRandomValueAssigned',
);

$query_string = http_build_query($data);

This should give you the result you're looking for.

这会给你你想要的结果。

http_build_query — Generate URL-encoded query string

http_build_query -生成url编码的查询字符串。

#4

$randomValue = array('username' => 'someValue' ); // same for other
foreach($array as &$value){
  $value = $value.'='.$randomValue[$value];
}

echo implode('&', $array);

#1

$keys = array('username', 'password', 'email');

$values = array('someusername', 'somepassword', 'someemail');

$data = array_combine($keys, $values);
