Please take a look at the following code and tell me what I'm doing wrong
here. I'm just not understanding why this isn't working:
<?php
$myArr = array( 'Key 1' => array( 'Key 1 1' => array( array( 'Key 1 1 1'
=> 'Value' ),
array( 'Key 1 1 2'
=> 'Value' )),
'Key 1 2' => array( array( 'Key 1 2 1'
=> 'Value' ),
array( 'Key 1 2 2'
=> 'Value' ))),
'Key 2' => array( 'Key 2 1' => array( array( 'Key 2 1 1'
=> 'Value' ),
array( 'Key 2 1 2'
=> 'Value' )),
'Key 2 2' => array( array( 'Key 2 2 1'
=> 'Value' ),
array( 'Key 2 2 2'
=> 'Value' ))));
echo '$myArr: <pre>' . print_r( $myArr, TRUE ) . '</pre><br>';
$myArrEncoded = json_encode( $myArr );
echo var_dump( $myArrEncoded ) . '<br><br>';
echo '$myArr encoded: ' . $myArrEncoded . '<br><br>';
try {
echo '$myArr decoded: <pre>' . json_decode( $myArrEncoded ) .
'</pre><br><br>'; // this is line 16
} catch( Exception $e ) {
echo 'Error: ' . var_dump( $e );
}
?>
When I run the above, I get the following. Please note that line 16 is in a
TRY block yet it still gives the error seen below:
$myArr:

(

*Catchable fatal error*: Object of class stdClass could not be converted to

*Now, if I change it so that I pass the second parameter as TRUE for
json_decode (ie, change my code as follows:
echo '$myArr decoded: <pre>' . json_decode( $myArrEncoded, TRUE ) .
'</pre><br><br>'; // this is line 16
), then here is what I get:
$myArr:

$myArr decoded:

What's going on here? Why isn't json_decode() properly decoding my string?
Is there something more I need to do?
Any help would be greatly appreciated!
thnx,
