not able to write code for traversing multidimentional array

[shivram D]

this is an array returned after parsing YAMl file using spyc api.

i want to write a code to to extract value related to key topic name and put in a separate 1d array say $topicnames

 

Array ( [1] => Array ( [topicname] => singapore travels [rev] => 250

                    [0] => Array ( [25] => Array ( ) [topicname] => airlines [rev] => 24 )

                    [1] => Array ( [35] => Array ( ) [topicname] => shubham [rev] => 65 ) )

          [2] => Array ( [topicname] => singapore entertainment [rev] => 210

                    [0] => Array ( [45] => Array ( ) [topicname] => night safari[rev] => 54 )

i tried using simple for loop but not working..

pl help me out.

hi joel..

the above is the output after executing the command print_r($data);

//$data is the array that contains yaml o/p.

// i put the array once again

 

Array ( [1] => Array ( [topicname] => singapore travels [rev] => 250

                [0] => Array ( [25] => Array ( ) [topicname] => shivram [rev] => 24 )

                [1] => Array ( [35] => Array ( ) [topicname] => shubham [rev] => 65 ) )

        [2] => Array ( [topicname] => singapore boom [rev] => 210

                [0] => Array ( [45] => Array ( ) [topicname] => appu [rev] => 54 )

                [1] => Array ( [65] => Array ( ) [topicname] => tep [rev] => 75 ) ) )

Put # code tags around the array so we can see the indentation.

[shivram D]

the array is

 

Array ( [1] => Array ( [topicname] => singapore travels [rev] => 250
                [0] => Array ( [25] => Array ( ) [topicname] => airlines[rev] => 24 )
                [1] => Array ( [35] => Array ( ) [topicname] => booking [rev] => 65 ) )
        [2] => Array ( [topicname] => singapore entertainment [rev] => 210
                [0] => Array ( [45] => Array ( ) [topicname] => night safari [rev] => 54 )

and you want a 1D array of which values??

 

containing the first level topicname indexes; singapore travels, singapore entertainment...

or the 2nd level topicname indexes; airlines, booking, night safari etc

[shivram D]

hi..

i want to display the content of the whole array as a list..shown below

so thought of taking in each level in 1d array and then display it..

if u have any other solution pl tell me

 

output:

singapore travel

• airlines
  
• booking
  

singapore entertainment

• night safari

you'll have to play around with some foreach loops

 

[shivram D]

thanks joel..

still a bit

il try with foreach..

[joel24]

you'll need some foreach inside of foreach's. something like this should give you the basic idea

i.e.

$array = array('firstLevel'=>array('2nd level'=>3));
foreach ($array as $value) {
    if (is_array($value)) {
        foreach ($value AS $key=>$secondLevel) {
            echo "key: $key, value: $secondLevel";
        }
    }
}
