As Ben already explained, we need the code to be able to help you.
Could it be that you think your array is multidimensional but it ain't
in the all cases.
You can try to use var_export() to see how the array looks like
syslog(LOG_INFO, var_export($myarray, true));
then look in the /var/log/messages (or where your system logs syslog
messages) to see how the array looked like.
You could also use a function like this (far from perfect) to display
the array:
function printArray($yourArray) {
foreach($yourArray as $value) {
if(is_array($value)) {
print "\n";
printArray($value);
} else {
print $value ." | ";
}
}
print "\n";
}
example:
$myarray = array( "something",
"something else",
array("name" => "Someone", "Age" => "50"),
array("name" => "Zimone", "Age" => "12", "Color" => "Blue")
);
printArray($myarray);
output something like:
something | something else |
Someone | 50 |
Zimone | 12 | Blue |
