php - converting ini to array in needed format using parse_ini_file - not getting desired output -

i have data pulled in query includes presenter information. formatted this:

[doe, john undefined] middle_name = e. department = psychology institution = special state university city = anywhere state = texas country = usa office_phone = 123-456-7891 cell_phone = 123-789-4578 email_address = john_doe@there.edu website = www.johndoe.edu  [doe, jane undefined] middle_name =  department = political science institution = special university city = anywhere state = indiana country = usa office_phone = 123-456-7891 cell_phone = 568-456-4589 email_address = janedoe@here.edu website =  

i need display this:

john doe, psychology, special state university

jane doe, political science, special university (each presenter on separate line)

i have tried this:

$cleanpresenters = parse_ini_file($data['presenters']);

and produces in error log:

 parse_ini_file([doe, john undefined]\nmiddle_name = e.\ndepartment = psychology\ninstitution = special state university\ncity = anywhere\nstate = texas\ncountry = usa\noffice_phone = 123-456-7891\ncell_phone = \nemail_address = john_doe@there.edu\nwebsite = \n\n): failed open stream: file name long in -file path name.proposalpdf.php on line 21, referer: filepath name 

i pretty php newbie , don't know next fix error , want. there may 1 presenter or there may several solution needs loop until runs through presenters. appreciated.

update: changing parse_ini_string , echo array, this:

array (     [middle_name] =>      [department] => political science     [institution] => special university     [city] => anywhere     [state] => indiana     [country] => usa     [office_phone] => 123-456-7891     [cell_phone] => 568-456-4589     [email_address] => janedoe@here.edu     [website] =>  )  

so far, good. how turn format desire?

i figured out based on research , example else had written.

 //convert presenter data array string       $cleanpresenters = parse_ini_string($data['presenters'],true);     foreach ($cleanpresenters $name=>$val1)      {             $name = trim($name);             $presenters[] = $name;             $convertedpresenters .= "$name, {$val1['department']}, {$val1['institution']}\n";     }; 

the above did trick. each presenter prints name, department, institution on single line. tips , points in right direction.
