Question

I have a multidimensional array and I want to have the output that only outputs the unique heading in “id” and “output” heading.

$job_rows = array(
                array("id" => 1, "output" => "file01", "output_type" => "FBX"),
                array("id" => 1, "output" => "file01", "output_type" => "JPG"),
                array("id" => 1, "output" => "file03", "output_type" => "JPL"),
                array("id" => 2, "output" => "file05", "output_type" => "FBX"),
                array("id" => 2, "output" => "file06", "output_type" => "JPX"),
                array("id" => 2, "output" => "file06", "output_type" => "JPG"),
                array("id" => 3, "output" => "file010", "output_type" => "FBX"),
                array("id" => 3, "output" => "file010", "output_type" => "JPA")
            );

Output that I want to accomplished.

ID : 1
    OUTPUTS :
    file01  FBX
            JPG
    file03  JPL
ID : 2
    OUTPUTS :
    file05  FBX
    file06  JPX
            JPG
ID : 3
    OUTPUTS :
    file010 FBX
            JPA


.. etc

basically combining the common IDs during echo’ing the results on page. Thanks

something like that:

$ID = -999;
$FILENAME = "";
foreach ($job_rows as $key => $value) {    
    foreach ($value as $k => $v) {
        print ($ID === $value['id'])?"":"ID : ".$value['id']."<br />";
        print ($FILENAME === "".$value['output'])? "":$value['output']." ";
        print ($k == 'output_type')?$v."<br />":"";
        $ID = $value['id'];
        $FILENAME = "".$value['output'];
    }
}

and it gives the output exactly like you wanted:

ID : 1
file01 FBX
JPG
file03 JPL
ID : 2
file05 FBX
file06 JPX
JPG
ID : 3
file010 FBX
JPA
