Question

I have a simple script that accepts a CSV file and reads every row into an array. I then cycle through each column of the first row (in my case it holds the questions of a survey) and I print them out. The survey is in french and whenever the first character of a question is a special character (é,ê,ç, etc) fgetcsv simply omits it.

Special characters in the middle of the value are not affected only when they are the first character.

I tried to debug this but I am baffled. I did a var_dump with the content of the file and the characters are definitely there:

var_dump(utf8_encode(file_get_contents($_FILES['csv_file']['tmp_name'])));

And here’s my code:

if(file_exists($_FILES['csv_file']['tmp_name']) && $csv = fopen($_FILES['csv_file']['tmp_name'], "r"))
    {
        $csv_arr = array();

        //Populate an array with all the cells of the CSV file
        while(!feof($csv))
        {
            $csv_arr[] = fgetcsv($csv);
        }

        //Close the file, no longer needed
        fclose($csv);

        // This should cycle through the cells of the first row (questions)
        foreach($csv_arr[0] as $question)
        {
            echo utf8_encode($question) . "<br />";
        }

    }

Have you already checked out the manual page on fgetcsv? There is nothing talking about that specific problem offhand, but a number of contributions maybe worth looking through if nothing comes up here.

There’s this, for example:

Note: Locale setting is taken into account by this function. If LANG is e.g. en_US.UTF-8, files in one-byte encoding are read wrong by this function.

Also, seeing as it’s always in the beginning of the line, could it be that this is really a hidden line break problem? There’s this:

Note: If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the auto_detect_line_endings run-time configuration option may help resolve the problem.

You may also want to try saving the file with different line endings.
