Saving Multiple File path to mysql using PHP - php

Question

Good Day. I have a php script that move multiple file in my directory..
$filepath = 'uploads/';
if (isset($_FILES['file'])) {
$file_id = $_POST['file_id'];
$count = 0;
foreach($_FILES['file']['tmp_name'] as $k => $tmp_name){
$name = $_FILES['file']['name'][$k];
$size = $_FILES['file']['size'][$k];
if (strlen($name)) {
$extension = substr($name, strrpos($name, '.')+1);
if (in_array(strtolower($extension), $file_formats)) { // check it if it's a valid format or not
if ($size < (2048 * 1024)) { // check it if it's bigger than 2 mb or no
$filename = uniqid()."-00000-". $name;=
$tmp = $_FILES['file']['tmp_name'][$k];
if (move_uploaded_file($tmp_name, $filepath . $filename)) {
$id = $file_id;
$file_path_array = array();
$files_path = $filepath . $filename;
$file_extension = $extension;
foreach($file_name as $k_file_path => $v_file_path){
$file_path_array[] = $v_file_path;
}
foreach($file_extension as $k_file_extension){
$file_extension_array[] = $v_file_extension;
}
$file_path = json_encode($files_path);
$file_name = str_replace("\/", "/",$file_path);
var_dump($file_name);
$update = $mysqli->query("UPDATE detail SET file_path='$file_name' WHERE id='$id'");
} else {
echo "Could not move the file.";
}
} else {
echo "Your file is more than 2MB.";
}
} else {
echo "Invalid file format PLEASE CHECK YOU FILE EXTENSION.";
}
} else {
echo "Please select FILE";
}
}
exit();
}
this is my php script that move file to 'uploads/' directory and i want to save the path to my database. i try to dump the $file_name and this is my example path how to save that to my database.. ? any suggestions ?
NOTE: i already move the file to uploads/ directory and i only want to save the path to my database

string(46) "uploads/5638067602dee-00000-samplePDF1.pdf"
string(46) "uploads/5638067602f8d-00000-samplePDF2.pdf"

Answer 1

if you must store them in one field..
inside the loop
$file_name_for_db[]=$file_name;
outside the loop:
$update = $mysqli->query("UPDATE detail SET file_path='".json_encode($file_name_for_db)."' WHERE id='$id'");
there is serialize() instead of json_encode() if you prefer
