fgetcsv escaping commas in title

[Big_Pat]

The following code is supposed to take a CSV file and insert to the database. First, I prepare the CSV file by replacing " with \" and , with \, then run a PHP function to prepare for insertion. It's not working the way I want it to. I've tried reading about delimiters and escapes but I've not found a solution. Can you help, please?

 

The excerpted code for the insertion is: 

if ($_FILES[csv][size] > 0) {
 
    $file   = $_FILES[csv][tmp_name];
    $handle = fopen($file, "r");
 
    do {
        if ($data[0]) {
            mysql_query("INSERT INTO songlist (track_number,title,
				etc, etc) VALUES 
			( 
			    '" . mysql_prep($data[0]) . "', 
			    '" . mysql_prep($data[1]) . "',
			    etc, etc
			) 
		    ");
        }
    } while ($data = fgetcsv($handle, 1000, ",", "'"));
    

and mysql_prep's code is: 

function mysql_prep($value)
{
    $magic_quotes_active = get_magic_quotes_gpc();
    $new_enough_php      = function_exists("mysql_real_escape_string"); // i.e. PHP >= v4.3.0
    if ($new_enough_php) { // PHP v4.3.0 or higher
        // undo any magic quote effects so mysql_real_escape_string can do the work
        if ($magic_quotes_active) {
            $value = stripslashes($value);
        }
        $value = mysql_real_escape_string($value);
    } else { // before PHP v4.3.0
        // if magic quotes aren't already on then add slashes manually
        if (!$magic_quotes_active) {
            $value = addslashes($value);
        }
        // if magic quotes are active, then the slashes already exist
    }
    return $value;
}

Is there a better function available? At the moment, commas in titles are being read as end-of-entries, despite being escaped.

I might've solved this myself, actually. When loading the csv file back into Excel, the title entry after the escaped comma has moved to the next column which, of course, I don't want. Seems I need to prepare my CSV file better.

there's no reason for you to modify the csv file. any piece of data that contains the comma delimiter will/should be enclosed in quotes and fgetcsv can correctly parse it.

[Big_Pat]

Well, I tried your suggestion but to no avail. One line of the CSV file reads like this, when opened in a text editor:

1,Ever After,Iron Tongue,"The Dogs Have Barked, the Birds Have Flown",Iron Tongue,08:14,2013,Southern Rock,-1,Neurot,US,,3219,2013

and the result is that the title has split to two columns with no quotes and no comma.

 

I then tried 

1,Ever After,Iron Tongue,"The Dogs Have Barked\, the Birds Have Flown",Iron Tongue,08:14,2013,Southern Rock,-1,Neurot,US,,3219,2013

but the result was " "The Dogs Have Barked" in one column and " the Birds Have Flown" " in the next, with no comma or escape \.

just use the default fgetcsv parameters. you have specifically used a single-quote as the field enclosure character. your data is using double-quotes (the default) as the field enclosure character.

[Big_Pat]

Ah, that's it. Excel added the double quotes around fields it had escaped. This works:

 

Thanks!

you are still doing too much. there's no need to modify the csv data. fgetcsv will read the original csv data by default.

Maybe it's just the vagaries of Excel, then, but if I simply enter the CSV as prepared by Excel it reads the comma in the album's title as a separator. In other words, 

1,Ever After,Iron Tongue,The Dogs Have Barked, the Birds Have Flown,Iron Tongue,08:14,2013,Southern Rock,-1,Neurot,US,,3219,2013

it sees the comma, understandably enough - the album's title is actually 'The Dogs Have Barked, the Birds Have Flown'.
