ok I got this array from the facebook API:
["affiliations"]=>
array(2) {
[0]=>
array(5) {
["nid"]=>
string(8) "16779497"
["name"]=>
string(11) "RWTH Aachen"
["type"]=>
string(7) "college"
["status"]=>
string(9) "Undergrad"
["year"]=>
string(1) "0"
}
[1]=>
array(5) {
["nid"]=>
string(8) "67109293"
["name"]=>
string(10) "Luxembourg"
["type"]=>
string(6) "region"
["status"]=>
string(0) ""
["year"]=>
string(1) "0"
}
}
now i wrote a function split_vars() that should write the value of
nid, name, type, status and year into one variable. since there are
more than one arrays (2 in this case) it would be good if i could have
the number of the array in the name of the variable so that
$affiliations_1_name should echo "Luxembourg".
I wrote this:
function split_vars(){
//This is just a part of the function, $user_info is the "big" array
where all the user_info data is
global $user_info, $affiliations, ${'affiliations_'.$i.'_nid'}, $
{'affiliations_'.$i.'_name'}, ${'affiliations_'.$i.'_type'}, $
{'affiliations_'.$i.'_status'}, ${'affiliations_'.$i.'_year'};
for($i=0;$i<count($user_info[0]['affiliations']);$i++){
$affiliations = $user_info[0]['affiliations'][$i];
${'affiliations_'.$i.'_nid'} = $affiliations['nid'];
${'affiliations_'.$i.'_name'} = $affiliations['name'];
${'affiliations_'.$i.'_type'} = $affiliations['type'];
${'affiliations_'.$i.'_status'} =
$affiliations['status'];
${'affiliations_'.$i.'_year'} = $affiliations['year'];
}
}
and outside of the variable I need to echo all these variable
variables.
But I get a Parse error: syntax error, unexpected ',' in line where
globals are declared.
