Hello,
I have been assigned a PHP problem for my programming class. I'm a beginner so I am finding it really hard to figure out what to do. I got this far thanks to the internet. The problem is to take a list of students, place it in a multidimensional array, sort it, then divide it in half and place each half in two new files. I can't seem to figure out the last step. This is my code so far:
<?php
$students=array_map('str_getcsv', file('student.txt'));
foreach ($student as $key => $row) $lastname [$key] = strtolower ($row[2]);
array_multisort($lastname, SORT_ASC, $students);
$groupone= array_slice($students,0,10);
$grouptwo=array_slice($students,10);
echo "<pre>" , print_r($groupone), "</pre>";
echo "<pre>" , print_r($grouptwo), "</pre>";
$firstgroup=fopen(firstgroup.txt, "w");
echo fwrite ($firstgroup,$groupone);
fclose($firstgroup);
At this point I get an error because I should use a string not an array to write the new file.
I don't actually know how to create a new file and export the information onto it, this is me guessing.
I would really really appreaciaite it if someone could help me out or point me in the right direction.
Thank you so much,
Camilla
