Question

Based on the answer provided here by user user1830391:
Some characters in CSV file are not read during PHP fgetcsv()

I updated my following code to use fgets() instead of fgetcsv(). It fixed my first character issue. thats no longer a prob… but…

what if the .csv file is seprated using ; instead of , Some fields will be wrapped using double quotes “”, for example one of my rows is split onto 2 lines. quote opened in the last element of one line and closed at the end of the first element of the next line. There is an “enter”(/n) in that cell. how should i treat this using this code. fgetcsv catches elements within double quotes but i dont think fgets() does.

Answer 1

I solved this by opening the file using fopen and fgets instead of fgetcsv() and writing a copy using utf8_encode for each line. Then i use the copy and put that through fgetcsv()

here is my updated code.

function runCSVtoArray() {
    // --> FOR IMPORT
    //Function that converts a CSV file to a PHP array.
    //echo '<span class="success">Chargement du fichier CSV pour importation MYSQL....</span><br />';
    $readCharsPerLine = (JRequest::getVar('charsPerLine') > 0) ? JRequest::getVar('charsPerLine') : 1500; /* Import as of 2012-04-16 seem to have max 800chars per line. 1500 is alot of extra. */
    putenv("LANG=fr_CA.UTF-8");
    setlocale(LC_ALL, 'fr_CA.UTF-8');
    //ini_set("auto_detect_line_endings", true);
    //iconv_set_encoding("internal_encoding", "UTF-8");
    $openfile = $this->imp['importPath'].$this->imp['csvFileName'];
    $utf8File = str_replace('.csv', '_utf8.csv', $openfile);

    if ( file_exists($openfile) ) {
        //echo '<span class="success">Fichier CSV trouvé....</span><br />';

        //rewrite the file in UTF8
        if (JRequest::getVar('encodeutf8')) {
            if (($handle = fopen($openfile, "r")) !== FALSE) {
                $newFileHandle = fopen($utf8File, 'w');     //NEW UTF8 FORMAT
                //fwrite($newFileHandle, "\xEF\xBB\xBF");
                while (($the_line = fgets($handle)) !== FALSE) {
                    fwrite($newFileHandle, utf8_encode($the_line));
                }   //End of while()
            }
            $openfile = $utf8File;
        }

        //echo '<span class="success">Ouverture du fichier : '.$openfile.'</span><br />';
