Insert many multi-level arrays into mysql base - php

Question

i have a function what separate my file's content. Example file:
001;"text1"
002;"text2"
003;"text3"
999
001;"tekst11"
Sometimes some indexes have a few values:
120;"text2"
120;"text3"
My function:
function parseCSV($file) {
$lines = file($file);
$output = array();
$i = -1;
foreach($lines as $line) {
$line = trim($line);
if($line == "999") {
$i++;
} else {
$ex = explode(";", $line, 2);
$val = str_replace("\"", "", $ex[1]);
//$dodaj = mysql_query("INSERT INTO `czynsz` (`$ex[$i]`) VALUES ('$val')");
if(isset($output[$i][$ex[0]])) {
if(is_array($output[$i][$ex[0]])) {
$output[$i][$ex[0]][] = $val;
} else {
$output[$i][$ex[0]] = array($output[$i][$ex[0]], $val);
}
} else {
$output[$i][$ex[0]] = $val;
}
$dodaj = mysql_query("INSERT INTO `czynsz` (`$ex[$i]`) VALUES ('$val')");
}
}
return $output;
}
$csvdata = parseCSV("woda.txt");
echo "<pre>\r\n";
print_r($csvdata);
echo "</pre>\r\n";
Above script makes me multi-level array tree and separate arrays from themselves by separator (999), because in my file are many arrays... When an index has many values - the script makes for him internal tree. For example:
Array
(
[0] => Array
(
[001] => 06-001-03-13
[002] => 06447
[003] => F
...
[097] =>
[120] => Array
(
[0] => text1
[1] => text2
)
)
[1] => Array
...
And there is my question:
I have a problem with save this mega array in my MySQL base. Every index in array have the same in data base. When the same index will have many values (ex. 120) it can be implode. Thank you with all my heart for any form of help... :(

Create a MySQL Table:
CREATE TABLE `czynsz` (
`id` INT NOT NULL ,
`value` VARCHAR( 255 ) NOT NULL
) ENGINE = InnoDB;
ALTER TABLE `czynsz` ADD UNIQUE `unique` ( `id` )
Then use the following php code to insert the data
ini_set('error_reporting', E_ALL); // just for debugging remove later
ini_set('display_erorrs', 1); // just for debugging remove later
function parseCSV($file) {
$lines = file($file);
$output = array();
$i = 0;
foreach($lines as $line) {
$line = trim($line);
if($line == "999") {
$i++;
continue;
}
list($id, $val) = explode(";", $line, 2);
$val = str_replace("\"", "", $val);
$result = mysql_query("
INSERT INTO `czynsz` (
id,
`value`
) VALUES (
'$id',
'$val'
) ON DUPLICATE KEY UPDATE
`value` = CONCAT(`value`, ', ', '$val')"
);
if(!$result) {
die(mysql_error());
}
if(isset($output[$i][$id])) {
if(is_array($output[$i][$id])) {
$output[$i][$id][] = $val;
} else {
$output[$i][$id] = array($output[$i][$id], $val);
}
} else {
$output[$i][$id] = $val;
}
}
return $output;
}

Use the PHP sledgehammer solution...
Assuming that you just want to store the array and don't need to query against distinct nodes, use the serialize function to turn your array into a string representation. You can easily pull the data and then use unserialize to get back the original array.
$s_arr = serialize($my_array);
$my_array = unserialize($s_arr);
If you need access to the nodes in the database, then I think that MySQL is not a good solution because of the complexity involved. If you want a key-value store, then you should look at a NoSQL solution such as Redis.
