Any of the following are valid:

$myArray = array();
$myArray[] = new Object();
$myArray[1] = new Object();
array_push($myArray, new Object);

What you should probably do is:

$hotelsDetail = array();

$details = new HotelDetails();
$details->setHotelInfo($rs);
$details->setPrice('150');

// assign it to the array here; you don't need the [0] index then
$hotelsDetail[] = $details;

In your specific case, the issue is that you should use ->, not .. The period isn't used in PHP to access attributes or methods of a class:

$hotelsdetail[0] = new hoteldetails();
$hotelsdetail[0]->sethotelinfo($rs);
$hotelsdetail[0]->setprice('150'); 

Note that I capitalized the class, object, and function names properly. Writing everything in lowercase is not considered good style.

As a side note, why is your price a string? It should be a number, really, if you ever want to do proper calculations with it.

All of these are quite obvious really. I'm only listing the Pythonic ways to do these things. Update: Examples should now work in both Python 2 and Python 3. In Python 2 you could substitute xrange() for range() and iteritems() for items() for efficiency.

Example 1

PHP

$php = array(1,2,3,4,5,6,7,8,9,10);
for (i < 10 ; $i ++)
echo i]."<br>";

Python (generally you iterate over lists in Python, instead of accessing by index):

lst = [1,2,3,4,5,6,7,8,9,10]
for item in lst:
    print(str(item) + "<br>")

Example 2

for (i < 10 ; $i ++)
echo i] = $i +1 ;

Python:

lst = range(1, 11)
for item in lst:
    print(item)

Or maybe:

lst = []
for i in range(10):
    lst.append(i + 1)
    print(lst[-1])     # prints out last element

Example 3

$php = array(1,2,3,4,5,6,7,8,9,10);
foreach (value)
echo $value."<br>";

Same as 1st

Example 4

$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
    $value = $value * 2;
}

Python:

lst = [1, 2, 3, 4]
lst = [val * 2 for val in lst]

Example 5

$arr = array("mot"=>"one", "hai"=>"two","ba"=> "three");
foreach (key => $value) {
    echo "Key: $key; Value: $value<br />\n";
}

Python (note that {...} creates a dict [dictionary] in Python, not a list/):

dct = {'mot': 'one', 'hai': 'two', 'ba': 'three'}
for key, value in dct.items():
    print("Key: %s; Value: %s<br />" % (key, value))

Example 6

$arr = array("one", "two","three");
while (list(value) = each($arr)) {
    echo "Key: $key; Value: $value<br />\n";
}

Python:

lst = ['one', 'two', 'three']
for key, value in enumerate(lst):
    print("Key: %d; Value: %s<br />" % (key, value))

Example 7

$arr = array("one", "two","three");
while ($element = each($arr)) {
    echo "Key: $element['key']; Value: $element['value']<br />\n";
}

There is no direct Python equivalent to this.

Example 8

$products = array( array("ITL","INTEL","HARD"),
                        array("MIR", "MICROSOFT","SOFT"),
                        array("Py4C", "pythonkhmer.wordpress.com","TUTORIAL")
                         );
for (row < 3; $row++)
{
    for ($col = 0; col++)
    {
        echo "|".$products[col];
    }
    echo "<br>";
}

Python:

products = [['ITL', 'INTEL', 'HARD'],
    ['MIR', 'MICROSOFT', 'SOFT'],
    ['Py4C', 'pythonkhmer.wordpress.com', 'TUTORIAL']]

for product in products:
    for item in product:
        print('|' + item)
    print('<br>')

Or maybe a more Pythonic version:

for product in products:
    print('|%s<br>' % ('|'.join(product)))

In the simplest case, it's probably sufficient to "cast" the array as an object:

$object = (object) $array;

Another option would be to instantiate a standard class as a variable, and loop through your array while re-assigning the values:

$object = new stdClass();
foreach ($array as $key => $value)
{
    $object->$key = $value;
}

As Edson Medina pointed out, a really clean solution is to use the built-in json_ functions:

$object = json_decode(json_encode($array), FALSE);

This also (recursively) converts all of your sub arrays into objects, which you may or may not want. Unfortunately it has a 2-3x performance hit over the looping approach.

Warning! (thanks to Ultra for the comment):

json_decode on different enviroments converts UTF-8 data in different ways. I end up getting on of values '240.00' locally and '240' on production - massive dissaster. Morover if conversion fails string get's returned as NULL

$JSON = file_get_contents('UserData.json'); // Parsing JSON from file. You can use your own way.
$Array = json_decode($JSON, true); // JSON (string) to Array
echo $Array["message"]; // Output: authenticated
echo $Array["data"]["id"]; // Output: 713

In your python script do something like

import json
#some code here
jsonStr = json.dumps(myListFromGooglePlaces)
#whatever you do to get it to php

and then as mentioned in my comment above

$arr = json_decode($json, true);

I hope that works for you.

This code

 $pages_array[1]->slug = "a";

is invalid anyways - you'll get a "strict" warning if you don't initialize the object properly. So you have to construct an object somehow - either with a constructor:

 $pages_array[] = new MyObject('index', 'title'....)

or using a stdclass cast

 $pages_array[] = (object) array('slug' => 'xxx', 'title' => 'etc')
