converting array into string in PHP

Question

I am trying to convert array into string
array converted from xml

 [ChargeableRateInfo] => Array(
 [NightlyRatesPerRoom] => Array
 (
 [NightlyRate] => Array
 (
 [0] => Array()
 [1] => Array()
 [0_attr] => Array(
 [promo] => false
 [rate] => 182.46
 [baseRate] => 182.46
 )
 [1_attr] => Array(
 [promo] => false
 [rate] => 182.46
 [baseRate] => 182.46
 )
 [2] => Array()
 )
 )
)

My try was :

foreach ($my_array['ChargeableRateInfo']['NightlyRatesPerRoom'] ['NightlyRate'] as $rates){
 print_r($rates['1_attr']['baseRate']);
 }

I used xml2array to convert xml with Attributes into array

• Wrikken: You don't tell us how you'd like your string to look....
• Sverri M. Olsen: As you can see from the syntax highlighting there is a syntax error in your loop. Also, what is the question?
• Nathan Hess: First things first. What do you want the end result to look like? Asking for it as a "string" is a bit ambiguous.
• Ahmed Nasr: My question is how can i loop baseRate because the last code is not working

Answer 1

Json_encode is the easiest way to convert multidimensional array to string. http://php.net/manual/en/function.json-encode.php

Answer 2

Try this:

foreach( $my_array['ChargeableRateInfo']['NightlyRatesPerRoom']['NightlyRate']
 as $k => $rates )
{
 if( array_key_exists( 'baseRate', $rates ) )
 {
 echo $rates['baseRate'], "\n";
 }
}
