php从存储在assoc数组中的数组中获取值

Question

Example:

$arraytest = array(
key => array("test"),
key2 => value2,
key3 => value3);

foreach ($arraytest as $key=>$val) {
echo $key. "=" .$val. "<br>";
}

Result:

key=Array
key2=value2
key3=value3

So, how can i get value which stored in $arraytest[0]? I need to use foreach in foreach for get

key=test
key2=value2
key3=value3

?

So, how can i get value which stored in $arraytest[0]?

Simply use $arraytest[0]. The Array is the value of $arraytest[0]. When you convert it to a string, it will just say "Array".

If instead, you want to iterate on that array, you already know how to do that.

foreach ($arraytest[0] as $key => $val) {
  echo $key, '=', $val, '<br/>';
}
