PHP inserting value only once - php

Question

I am trying to add categories in a database. Things is the script is reading the categories from a product list, therefore there are duplicate values as it'd be like reading
PRODUCT NAME - DETAIL 1 - DETAIL 2 - CATEGORY
Rinse and repeat.
I have my code down and the insert works but it stops at the first product's category value as if I put it out of my foreach loop.
<?php
$filecsv = 'pricelist.csv';
$rows = file($filecsv);
foreach($rows as $row){
$c1 = explode('|', $row);
if($c1['6'] == "not available"){
unset($c1);
continue;
}
//echo '<pre>'.print_r($c1[9], true).'</pre>';
$bool = Db::getInstance()->executeS("SELECT CASE WHEN EXISTS (SELECT * FROM b2b_category WHERE name_b2bcategory IN ('".$c1[9]."') ) THEN true ELSE false end");
foreach($bool[0] as $keyB => $valueB){
$verify = $valueB;
$count = 0;
if($valueB != 1){
Db::getInstance()->execute("INSERT INTO b2b_category (id_b2bcategory, name_b2bcategory, position_b2bcategory, active_b2bcategory) VALUES (".$count.", '".$c1[9]."', '0', '0')");
$count++;
//echo '<pre>'.print_r($valueB, true).'</pre>';
}
}
}
?>
I also want to point out my $c1 variable has multiple arrays. It's not one multi-dimensional array.
So it's like
Array {
etc
}
Array {
etc
}
Array {
etc
}
Array {
etc
}
Array {
etc
}

Since you're using MySQL, you can use on duplicate key update clause:
Db::getInstance()->execute(
"INSERT INTO b2b_category (id_b2bcategory, name_b2bcategory, position_b2bcategory, active_b2bcategory)
VALUES (".$count.", '".$c1[9]."', '0', '0')
on duplicate key update name_b2bcategory = '".$c1[9]."'"
);
You can also use a select count(1) instead of when exists:
$cnt = Db::getInstance()->executeS("SELECT count(1) FROM b2b_category WHERE name_b2bcategory IN = '".$c1[9]."'");
if($cnt[0] == 0) {
Db::getInstance()->execute("INSERT INTO b2b_category (id_b2bcategory, name_b2bcategory, position_b2bcategory, active_b2bcategory) VALUES (".$count.", '".$c1[9]."', '0', '0')");
$count++;
}

I fixed it by using this function and using my same .csv file as a multi-dimensional array. Before I couldn't operate with it due to my output being a fake array, it was recognized as string if anything. With this I could easily operate on the sub-arrays through the standard array PHP functions shortly after.
<?php
function csv_to_multidimension_array($filename, $delimiter)
{
if(!file_exists($filename) || !is_readable($filename)) {
return false;
}
$header = NULL;
$data = array();
if (($handle = fopen($filename, 'r')) !== false) {
while (($row = fgetcsv($handle, 1000, $delimiter)) !== false ) {
$data[] = $row;
}
fclose($handle);
}
return $data;
}
