php object to array

1.

//PHP stdClass Object转array function object_array($array) { if(is_object($array)) { $array = (array)$array; } if(is_array($array)) { foreach($array as $key=>$value) { $array[$key] = object_array($value); } } return $array; }

2.

$array = json_decode(json_encode(simplexml_load_string($xmlString)),TRUE);

3.

function object2array_pre(&$object) { if (is_object($object)) { $arr = (array)($object); } else { $arr = &$object; } if (is_array($arr)) { foreach($arr as $varName => $varValue){ $arr[$varName] = $this->object2array($varValue); } } return $arr; }

4. If the amount of data is 10W, the execution will take 1 second, and the structure will It is more complicated and can reach 3s. The performance is too poor. You can replace it with the following:

function object2array(&$object) { $object = json_decode( json_encode( $object),true); return $object; }

json_decode(json_encode($array),true)

The purpose of multi-layer array and object conversion is very simple, which is convenient for processing multi-layer numbers in WebService Conversion of groups and objects [Recommended study: "PHP Video Tutorial"]

Simple (array) and (object) can only process single-layer data. For multi-layer arrays and Object conversion does nothing.

Through json_decode(json_encode($object), the object can be converted into an array at one time, but problems will occur when encountering non-utf-8 encoded non-ascii characters in the object, such as gbk Chinese, not to mention json_encode and The performance of decode is also questionable.

The code below:

foo = "Test data"; $init->bar = new stdClass; $init->bar->baaz = "Testing"; $init->bar->fooz = new stdClass; $init->bar->fooz->baz = "Testing again"; $init->foox = "Just test"; // Convert array to object and then object back to array $array = objectToArray($init); $object = arrayToObject($array); // Print objects and array print_r($init); echo "\n"; print_r($array); echo "\n"; print_r($object); ?>
