Hi there,

Welcome to the first WebLive Help Tutorial.

Today we'll give out two very useful PHP functions:

• Convert/Parse Array to Object
• Convert/Parse Object to Array

Code: Select all

<?php
function parseArrayToObject($array) {
   $object = new stdClass();
   if (is_array($array) && count($array) > 0) {
      foreach ($array as $name=>$value) {
         $name = strtolower(trim($name));
         if (!empty($name)) {
            $object->$name = $value;
         }
      }
   }
   return $object;
}

function parseObjectToArray($object) {
   $array = array();
   if (is_object($object)) {
      $array = get_object_vars($object);
   }
   return $array;
}
?>


Usage:

Convert Array $a to Object $o

Code: Select all

<?php
$a = array (
   'index_0' => 'value_0',
   'index_1' => 'value_1'
);

$o = parseArrayToObject($a);

//-- Now you can use $o like this:
echo $o->index_0;//-- Will print 'value_0'
?>


Convert Object $o to Array $a

Code: Select all

<?php
$o = new stdClass();
$o->index_0 = 'value_0';
$o->index_1 = 'value_1';

$a = parseObjectToArray($o);

//-- Now you can use $a like this:
echo $a['index_0'];//-- Will print 'value_0'
?>


Use it well!

Just what I was looking for!!! Thanks!

a recursive way to convert multidimensional arrays and objects

Code: Select all

function array2object($data) {
   if(!is_array($data)) return $data;
   
   $object = new stdClass();
   if (is_array($data) && count($data) > 0) {
      foreach ($data as $name=>$value) {
         $name = strtolower(trim($name));
         if (!empty($name)) {
            $object->$name = array2object($value);
         }
      }
   }
   return $object;
}
function object2array($data){
   if(!is_object($data) && !is_array($data)) return $data;

   if(is_object($data)) $data = get_object_vars($data);

   return array_map('object2array', $data);
}

Thanks marcel for the tip

$name = strtolower(trim($name));

great function indeed, but can't understand why u use strtolower

$name = strtolower(trim($name));

great function indeed, but can't understand why u use strtolower

He uses strtolower because object's properties ARE CaSe-sEnSiTiVe, unlinke array alphanumeric keys which aren't.

That isn't needed though, but if an array has a key like "Item1", you'll have to use $object->Item1 and not $object->item1
