PHP inserting parsed values from text file into MySQL DB - php

Question

I'm new to PHP and am trying to parse certain text from a txt file, and then insert the text into a MySQL database. So, let's get more specific. The file's format is as such, and it is repeated through the document end. the ellipses represent the previous and next tones.
...
[Tone27]
Atone = 707.3
Btone = 746.8
Btonelength = 3
Btonedebounce = 1
Description = Fire Department 1
mp3_Emails = email#address.com,email2#address.com,email3#address.com
amr_Emails = email2#textmessaging.com,email1#textmessaging.com
alert_command = c:\test.bat
post_email_command = c:\test2.bat
radio_frequency = 154.475
exclude_from = 13:25
exclude_to = 13:35
exclude_emails = email2#textmessaging.com,email2#address.com
...
What I want to do is parse the first items(e.g. '[tone27]') in each "tone block" from the file and insert it into the first field of a NEW row in the db. I then need to evaluate what comes before each line's " = ", for instance "Atone," and insert what comes after that line's " = ", for instance "707.3" into a field by that name. so, this row may look like this in the db:
$id | [tone27] | 707.3 |746.8 | 3 | 1 | Fire Department 1 |email1#x.com,email2#x.com,e...|...
and so on...
i've been able to isolate each thing by performing string functions, but am unsure of how to set up a loop that would insert each value properly. Here's the code I used to isolate them, but it's not helping at all with actually getting them into the database.
$txt_file = file_get_contents('config/tones.txt');
$rows = explode("\n", $txt_file);
foreach($rows as $row => $data)
{
$row_data = explode(' = ', $data);
if ((isset($row_data[0])) && ($row_data[0] !== " " )){
$info[$row]['attribute'] = $row_data[0];
$info_attribute = trim($info[$row]['attribute']);
}
if (isset($row_data[1])){
$info[$row]['value'] = $row_data[1];
$info_value = trim($info[$row]['value']);
//display data
echo 'Row ' . $row . ' Attribute: ' . $info_attribute . '<br />';
echo 'Row ' . $row . ' Value: ' . $info_value . '<br />';
} elseif (($info[$row]['attribute']) && (!empty($info_attribute))) {
echo "<br>";
echo 'Row ' . $row . ' Attribute: ' . $info_attribute . '<br />';
continue;
}
I'M A NOOB, NO DOUBT. I'M LOST. Thanks in advance for your help!!!
****|| EDIT ||****
Thanks for all of the excellent answers! here's what I've resultingly come up with. No queries yet, just a simple dash of the read portion of CRUD, but the code will be the same, only with queries. A big thanks to #leepowers for introducing me to the wonderful parse_ini_file() function.
foreach(parse_ini_file("config/tones.txt", true) as $k => $v){
extract($v, EXTR_SKIP);
echo "<br>";
echo $k . "<br>";
foreach($v as $sv => $ssv){
$lcase_sv = strtolower($sv);
if (trim($lcase_sv) == 'amr_emails'){
echo "sv: amr_Emails:<br>";
echo "ssv:<br>";
$eA = explode(',', trim($ssv));
foreach($eA as $eK => $eV){
echo "email" . filter_var($eK + 1, FILTER_SANITIZE_NUMBER_INT) . ": " . $eV . "<br>";
}
} elseif (trim($lcase_sv) == 'mp3_emails'){
echo "ssv:<br>";
$eA = explode(',', trim($ssv));
foreach($eA as $eK => $eV){
echo "email" . filter_var($eK + 1, FILTER_SANITIZE_NUMBER_INT) . ": " . $eV . "<br>";
}
}else {
echo "sv: " . $sv .", " . "s: " . $ssv . "<br>";
}
}
}

Answer 1

Use parse_ini_file to load the data structure into an array.
From there you can build and execute SQL statements:
$entries = parse_ini_file("config/tones.txt", true);
foreach ($entries as $section => $fields) {
extract($fields, EXTR_SKIP);
$sql = "INSERT INTO mytable (section, atone, btone) VALUES ($section, '$Atone', '$Btone'";
....
}
Of course, you'll need to prepare and escape the SQL statement before executing it.

Answer 2

parse_ini_file($source); return an associative array
$query = 'INSET INTO ... (key, value) VALUES (:key, :value)';
$stmt = DB::prepare($query);
foreach( parse_ini_file($source) as $key => $value )
{
$stmt->execute(array(':key' => $key, ':source' => $source));
}
This example use PDO
Just output of file in loop is:
foreach( parse_ini_file($source) as $key => $value )
{
echo $key; // Atone in first loop
echo $value; //707.3 in first loop
// BUT NOT USE THIS!!! use mysqli or PDO
mysql_query("INSERT INTO ... (key, value) VALUES ($key, $value)");
}

Answer 3

Here's another way to do it. Just need to modify it according to you needs (number of rows/credentials). It's better to use PDO.
$username = 'yourusername';
$password = 'yourpass';
try {
$conn = new PDO('mysql:host=127.0.0.1;dbname=yourdbname', $username, $pass);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo 'successfully connected';
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
foreach(parse_ini_file('yourfile.ini', true) as $row)
{
try {
// just adjust the number of columns accordingly
$stmt = $conn->prepare('insert into tablename values(?,?,?,?,?,?,?,?,?,?,?,?,?)');
// $row contains the values to insert
$stmt->execute($row);
echo 'rows affected' . $stmt->rowCount(); // 1
}catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
}
