How to create an array from a CSV file using PHP and the fgetcsv function

Can someone kindly provide a code to create an array from a CSV file using fgetcsv?

I've used the following code to create an array from a simple CSV file, but it doesn't work right when one of my fields has multiple commas - such as addresses.

$lines =file('CSV Address.csv');

foreach($lines as $data)
{
list($name[],$address[],$status[])
= explode(',',$data);
}

*Also, str_getcsv is not supported by my hosting service.

The above code doesn't work with the following CSV file example. First column is name, second column is address, third column is marital status.

Scott L. Aranda,"123 Main Street, Bethesda, Maryland 20816",Single
Todd D. Smith,"987 Elm Street, Alexandria, Virginia 22301",Single
Edward M. Grass,"123 Main Street, Bethesda, Maryland 20816",Married
Aaron G. Frantz,"987 Elm Street, Alexandria, Virginia 22301",Married
Ryan V. Turner,"123 Main Street, Bethesda, Maryland 20816",Single

Like you said in your title, fgetcsv is the way to go. It's pretty darn easy to use.

$file = fopen('myCSVFile.csv', 'r');
while (($line = fgetcsv($file)) !== FALSE) {
  //$line is an array of the csv elements
  print_r($line);
}
fclose($file);

You'll want to put more error checking in there in case fopen() fails, but this works to read a CSV file line by line and parse the line into an array.

I think the str_getcsv() syntax is much cleaner, it also doesn't require the CSV to be stored in the file system.

$csv = str_getcsv(file_get_contents('myCSVFile.csv'));

echo '<pre>';
print_r($csv);
echo '</pre>';

Or for a line by line solution:

$csv = array();
$lines = file('myCSVFile.csv', FILE_IGNORE_NEW_LINES);

foreach ($lines as $key => $value)
{
    $csv[$key] = str_getcsv($value);
}

echo '<pre>';
print_r($csv);
echo '</pre>';

Or for a line by line solution with no str_getcsv():

$csv = array();
$file = fopen('myCSVFile.csv', 'r');

while (($result = fgetcsv($file)) !== false)
{
    $csv[] = $result;
}

fclose($file);

echo '<pre>';
print_r($csv);
echo '</pre>';

I have created a function which will convert a csv string to an array. The function knows how to escape special characters, and it works with or without enclosure chars.

$dataArray = csvstring_to_array( file_get_contents('Address.csv'));

I tried it with your csv sample and it works as expected!

function csvstring_to_array($string, $separatorChar = ',', $enclosureChar = '"', $newlineChar = "\n") {
    // @author: Klemen Nagode
    $array = array();
    $size = strlen($string);
    $columnIndex = 0;
    $rowIndex = 0;
    $fieldValue="";
    $isEnclosured = false;
    for($i=0; $i<$size;$i++) {

        $char = $string{$i};
        $addChar = "";

        if($isEnclosured) {
            if($char==$enclosureChar) {

                if($i+1<$size && $string{$i+1}==$enclosureChar){
                    // escaped char
                    $addChar=$char;
                    $i++; // dont check next char
                }else{
                    $isEnclosured = false;
                }
            }else {
                $addChar=$char;
            }
        }else {
            if($char==$enclosureChar) {
                $isEnclosured = true;
            }else {

                if($char==$separatorChar) {

                    $array[$rowIndex][$columnIndex] = $fieldValue;
                    $fieldValue="";

                    $columnIndex++;
                }elseif($char==$newlineChar) {
                    echo $char;
                    $array[$rowIndex][$columnIndex] = $fieldValue;
                    $fieldValue="";
                    $columnIndex=0;
                    $rowIndex++;
                }else {
                    $addChar=$char;
                }
            }
        }
        if($addChar!=""){
            $fieldValue.=$addChar;

        }
    }

    if($fieldValue) { // save last field
        $array[$rowIndex][$columnIndex] = $fieldValue;
    }
    return $array;
}

$arrayFromCSV =  array_map('str_getcsv', file('/path/to/file.csv'));
