creating table with a csv file to database mysql - php

Question

I'm trying to create a table using my csv file with fields and I also have column headers inside my csv file. However, when I try to run it.. it just shows and gives me a query... I'm trying to find out what seems to be the problem and I'm stuck with it... can you help me on this? Thank
Here's my code
<?php
$server = "localhost";
$username = "root";
$pass = "";
$dbname = "test";
$conn = new PDO("mysql:host=$server;dbname=$dbname", $username,
$pass);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// Parameters: filename.csv table_name
$file = 'C:\Users\HP\Desktop\ACC.DBF.csv';
$table = 'acc';
// get structure from csv and insert db
ini_set('auto_detect_line_endings',TRUE);
$handle = fopen($file,'r');
// first row, structure
if ( ($data = fgetcsv($handle) ) === FALSE ) {
echo "Cannot read from csv $file";die();
}
$fields = array();
$field_count = 0;
for($i=0;$i<count($data); $i++) {
$f = strtolower(trim($data[$i]));
if ($f) {
// normalize the field name, strip to 20 chars if too long
$f = substr(preg_replace ('/[^0-9a-z]/', '_', $f), 0, 20);
$field_count++;
$fields[] = $f.' VARCHAR(255)';
}
}
$sqlcreate = $conn->prepare("CREATE TABLE $table (" . implode(', ', $fields) . ')');
$sqlcreate->execute();
echo "Create Table success" . "<br /><br />";
//$db->query($sql);
while ( ($data = fgetcsv($handle) ) !== FALSE ) {
$fields = array();
for($i=0;$i<$field_count; $i++) {
$fields[] = '\''.addslashes($data[$i]).'\'';
}
$sqlinsert = $conn->prepare("Insert into $table values(" . implode(', ',
$fields) . ')');
$sqlinsert->execute();
echo "Insert Table success" ;
}
fclose($handle);
ini_set('auto_detect_line_endings',FALSE);
?>

I have created a utility script which does the same thing that you are trying.. Please check if it helps you.
<?php
$fileName = './WP.csv';
function connectDB()
{
$server = "mysql2345";
$username = "root";
$pass = "root";
$dbname = "sc1";
$conn = new PDO("mysql:host=$server;dbname=$dbname", $username, $pass);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $conn;
}
function createDb($csv_path, $db)
{
if (($csv_handle = fopen($csv_path, "r")) === false) {
throw new Exception('Cannot open CSV file');
}
if(!isset($delimiter)) {
$delimiter = ',';
}
if (!isset($table)) {
$table = preg_replace("/[^A-Z0-9]/i", '', basename($csv_path));
}
if (!isset($fields)) {
$fields = array_map(function ($field){
return $field;
}, fgetcsv($csv_handle, 0, $delimiter));
}
$create_fields_str = join(', ', array_map(function ($field){
return "$field VARCHAR(200) NULL";
}, $fields));
echo $create_table_sql = "CREATE TABLE IF NOT EXISTS $table ($create_fields_str)";
$db->query($create_table_sql);
return ['table'=>$table, 'fields'=>$fields];
}
function loadData($fileName, $tableName, $fields, $db)
{
$fieldStr = implode(',', $fields);
$query = <<<eof
LOAD DATA LOCAL INFILE '$fileName'
INTO TABLE $tableName
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\r'
($fieldStr)
eof;
echo $query;
$db->query($query);
}
$db = connectDB();
$tableInfo = createDb($fileName, $db);
loadData($fileName, $tableInfo['table'], $tableInfo['fields'], $db);
