PHP Moving an array into different text files? -

i've been given list of data , need split , move different text files. i've tried few things far cant seem work.

<?php  /* *order file based on surname (col 2) *create 2 new text files - class , b *split source text 2 equal lists *format them: id, firstname, lastname. words must first letter caps *move each list new file. *close files */  //this function converts every attribute/variable passed sentence case function uppercase($convert) {     return ucwords($convert); }  //this function compares 2 items see 1 higher //src: http://php.net/manual/en/function.usort.php function cmp($a, $b) { $compresult = strcmp($a[1], $b[1]);  if ($compresult == 0) {     return strcmp($a[2], $b[2]); }else {     return $compresult; } }  //this function gets rid of whitespace not needed function cut($c) {     return trim($c, " \n\r\0"); }  //open file $myfile = fopen("students.csv", "r");  echo "a";  //initialise array, giving them 'headers' $array = array();  echo "b";  //sort through data, moving multidimentional array , setting   first letter in each item uppercase $i=0;  while(!feof($myfile)){ $line = fgets($myfile);  $pieces = explode(",", $line); $array[$i][0] = $pieces[0]; $array[$i][1] = cut(uppercase($pieces[2])); $array[$i][2] = cut(uppercase($pieces[1]));  $i++; }     echo "c";  //sort file second item in array usort($array, "cmp"); echo array_shift($array)."<br>";  echo "d";  //create class files $filea = fopen("class 1.txt", "w"); $fileb = fopen("class 2.txt", "w");  echo "e";  //get size of array $arraylength = count($array);  //half array length( $half = ceil($arraylength /= 2); //echo $half;  //echo $arraylength."</br>"; echo "f";  echo "<pre>"; print_r($array); echo "</br>";  //move first class text file $k = 0;  foreach ($array $key){     echo $key[0];       if ($k < $half) {         $current = file_get_contents($filea);         $current .= $key;     } }   echo "g";  fclose($filea); fclose($fileb); fclose($myfile);  echo "h"; 

when runs, following line recurring each item in array

warning: file_get_contents() expects parameter 1 valid path, resource given in c:\xampp\htdocs\phplabs\ee1600assignment.php on line 93

the document has 25 items this:

123, billy, bobs 

any appreciated. thank you

file_get_contents expects file path, providing file handler. want instead fgets($filea).

alternatively, if want read complete file (it's not entirely clear code), can use fread($filea).
