如何使用stdClass对象解析PHP数组

Question

Following is the array with stdClass Object

Array
(
    [0] => stdClass Object
        (
            [Number] => 5
            [Content] => 00666
        )

    [1] => stdClass Object
        (
            [Number] => 7
            [Content] => 1018456550591052212900797790669502
        )
)

What I want to get value of Content corresponding to Number

eg. For Number 5 get value 00666

Thank in advance.

Answer 1

add this function:

function returnContent($myObjectArray, $number)
{
   foreach($myObjectArray as $obj){
      if ($obj->Number == $number)
         return $obj->Content;
      }
   }
   return "number not in array"; //or some other value to denote an error
}

call the function something like this:

echo returnContent($objArray, 5);

or assign it to a variable:

$content = returnContent($objArray, 5);

just be sure to check if the number existed:

if ($content != "number not in array"){ //or whatever value you assigned to denote a failure
   //do something
}

Answer 2

You can make a function for this:

function getContent($needle, $haystack) {
  foreach($haystack as $v) if($needle==$v->Number) return $v->Content;
  return null;
}

To use it use:

$result = getContent(5, $myArray);
if($result===null) die('Value not found.');
// Use result however you want now

Answer 3

$myObjectArray= myObjectArray() // array of objects

foreach($myObjectArray as $val) {
    echo $val->Content;
}

It will print `00666` and `1018456550591052212900797790669502`
