Invalid arguments passed in implode() - php

Question

So I have a CSV file that I'm trying to make into a table.
I gave up on the import GUI after too many errors, and am trying to accomplish the import through a php file.
//create table with KNOWN values
mysql_query("CREATE TABLE uri_faculty
(
id INT NOT NULL AUTO_INCREMENT,
PRIMARY KEY(id),
id INT(15),
lname VARCHAR(50),
fname VARCHAR(50),
mi VARCHAR(3),
Spc_Title VARCHAR(50),
title VARCHAR(50),
deptid INT(5),
dept VARCHAR(50),
degree1 VARCHAR(10),
earned1 INT(4),
school1 VARCHAR(75),
degree2 VARCHAR(10),
earned2 INT(4),
school2 VARCHAR(75),
degree3 VARCHAR(10),
earned3 INT(4),
school3 VARCHAR(75),
degree4 VARCHAR(10),
earned4 INT(4),
school4 VARCHAR(75),
degree5 VARCHAR(10),
earned5 INT(4),
school5 VARCHAR(75),
degree6 VARCHAR(10),
earned6 INT(4),
school6 VARCHAR(75)
)");
//Get CSV file
$getfile = 'faculty_delim2.csv';
$csvfopen = fopen($getfile, "r");
//loop to fill csvget with arrays
for($i=0;!feof($csvfopen);$i++){
$array = fgetcsv($csvfopen);
$insert = implode("','", $array);
//to exclude the first 2 lines (titles of document)
if($i>=1){
//values to be inserted into SQL are displayed
//echo var_dump($array[$i])." <br> ";
$sqlval = $insert;
// var_dump($sqlval);
//the while loop will constantly place values into the database until the file is finished
mysql_query("INSERT INTO uri_faculty (id,lname,fname,mi,Spc_Title,title,deptid,dept,
degree1,earned1,school1,
degree2,earned2,school2,
degree3,earned3,school3,
degree4,earned4,school4,
degree5,earned5,school5,
degree6,earned6,school6,) VALUES ('$sqlval')
");
}
}
fclose($csvfopen);
echo "complete";
?>
I keep getting an error saying that implode is receiving incorrect parameters, yet every bit of documentation I've found says that I am correct.
I changed the permissions of the file, and it is in the right place.

Instead of this:
for($i=0;!feof($csvfopen);$i++){
$array = fgetcsv($csvfopen);
I would write this:
while ($array = fgetcsv($csvfopen)) {
The loop will automatically finish when there are no more rows to read. Your error is probably an edge case, where the file still thinks it is not at feof but in spite of that, there are no more rows, and fgetcsv returns false.
By the way, two other issues:
You will run into another error soon:
. . . degree6,earned6,school6,) VALUES . . .
You must not put a comma after the last column. Write this instead:
. . . degree6,earned6,school6) VALUES . .
You are wide open to SQL injection issues. What happens when one of your CSV fields contains an apostrophe? You should learn how to use PDO with query parameters. Or failing that, use escaping:
$insert = implode("','", array_map('mysql_real_escape_string', $array));
Finally, you should consider skipping fgetcsv and use LOAD DATA INFILE. Then all your CSV issues, and escaping issues just go away.
mysql_query("LOAD DATA LOCAL INFILE 'faculty_delim2.csv' INTO TABLE uri_faculty IGNORE 2 LINES");
