Cara membuat array dari file CSV menggunakan PHP dan fungsi fgetcsv

Bisakah seseorang dengan ramah memberikan kode untuk membuat array dari file CSV menggunakan fgetcsv?

Saya telah menggunakan kode berikut untuk membuat larik dari file CSV sederhana, tetapi tidak berfungsi dengan benar ketika salah satu bidang saya memiliki banyak koma - seperti alamat.

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

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

* Selain itu, str_getcsv tidak didukung oleh layanan hosting saya.

Kode di atas tidak berfungsi dengan contoh file CSV berikut. Kolom pertama adalah nama, kolom kedua adalah alamat, kolom ketiga adalah status perkawinan.

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

Seperti yang Anda katakan di judul Anda, fgetcsv adalah cara yang tepat. Sangat mudah digunakan.

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

Anda akan ingin meletakkan lebih banyak pemeriksaan kesalahan di sana jika fopen()gagal, tetapi ini berfungsi untuk membaca file CSV baris demi baris dan mengurai baris menjadi array.

Saya pikir sintaks str_getcsv () jauh lebih bersih, juga tidak memerlukan CSV untuk disimpan di sistem file.

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

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

Atau untuk solusi baris demi baris:

$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>';

Atau untuk solusi baris demi baris tanpa 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>';

Saya telah membuat fungsi yang akan mengubah string csv menjadi array. Fungsi tersebut mengetahui cara keluar dari karakter khusus, dan berfungsi dengan atau tanpa karakter enklosur.

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

Saya mencobanya dengan sampel csv Anda dan berfungsi seperti yang diharapkan!

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'));

Pertanyaan lama, tapi masih relevan untuk pengguna PHP 5.2. str_getcsv tersedia dari PHP 5.3. Saya telah menulis sebuah fungsi kecil yang bekerja dengan fgetcsv itu sendiri.

Di bawah ini adalah fungsi saya dari https://gist.github.com/4152628 :

function parse_csv_file($csvfile) {
    $csv = Array();
    $rowcount = 0;
    if (($handle = fopen($csvfile, "r")) !== FALSE) {
        $max_line_length = defined('MAX_LINE_LENGTH') ? MAX_LINE_LENGTH : 10000;
        $header = fgetcsv($handle, $max_line_length);
        $header_colcount = count($header);
        while (($row = fgetcsv($handle, $max_line_length)) !== FALSE) {
            $row_colcount = count($row);
            if ($row_colcount == $header_colcount) {
                $entry = array_combine($header, $row);
                $csv[] = $entry;
            }
            else {
                error_log("csvreader: Invalid number of columns at line " . ($rowcount + 2) . " (row " . ($rowcount + 1) . "). Expected=$header_colcount Got=$row_colcount");
                return null;
            }
            $rowcount++;
        }
        //echo "Totally $rowcount rows found\n";
        fclose($handle);
    }
    else {
        error_log("csvreader: Could not read CSV \"$csvfile\"");
        return null;
    }
    return $csv;
}

Coba ini..

function getdata($csvFile){
    $file_handle = fopen($csvFile, 'r');
    while (!feof($file_handle) ) {
        $line_of_text[] = fgetcsv($file_handle, 1024);
    }
    fclose($file_handle);
    return $line_of_text;
}


// Set path to CSV file
$csvFile = 'test.csv';

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

            [2] => test
            [3] => test
            [4] => test
            [5] => 
            [6] => 6.00
        ));

Fungsi ini akan mengembalikan array dengan nilai Header sebagai kunci array.

function csv_to_array($file_name) {
        $data =  $header = array();
        $i = 0;
        $file = fopen($file_name, 'r');
        while (($line = fgetcsv($file)) !== FALSE) {
            if( $i==0 ) {
                $header = $line;
            } else {
                $data[] = $line;        
            }
            $i++;
        }
        fclose($file);
        foreach ($data as $key => $_value) {
            $new_item = array();
            foreach ($_value as $key => $value) {
                $new_item[ $header[$key] ] =$value;
            }
            $_data[] = $new_item;
        }
        return $_data;
    }

Untuk mendapatkan array dengan kunci yang tepat, Anda dapat mencoba ini:

// Open file
$file = fopen($file_path, 'r');

// Headers
$headers = fgetcsv($file);

// Rows
$data = [];
while (($row = fgetcsv($file)) !== false)
{
    $item = [];
    foreach ($row as $key => $value)
        $item[$headers[$key]] = $value ?: null;
    $data[] = $item;
}

// Close file
fclose($file);

Saya menemukan kode yang cukup mendasar ini. Saya pikir ini bisa bermanfaat bagi siapa saja.

$link = "link to the CSV here"
$fp = fopen($link, 'r');

while(($line = fgetcsv($fp)) !== FALSE) {
    foreach($line as $key => $value) {
        echo $key . " - " . $value . "<br>";
    }
}


fclose($fp);

Jika Anda ingin setiap baris berada dalam array, dan setiap sel dalam baris dalam array:

$file = fopen('csvFile.csv', 'r');              // Open the file                     
while (($line = fgetcsv($file)) !== FALSE) {    // Read one line
    $array[] =$line;                            // Add the line in the main array
}
echo '<pre>';
print_r($array);   //print it out
echo '</pre>'; 
fclose($file);

Coba kode ini:

function readCsv($file)
{
    if (($handle = fopen($file, 'r')) !== FALSE) {
        while (($lineArray = fgetcsv($handle, 4000)) !== FALSE) {
            print_r(lineArray);
        }
        fclose($handle);
    }
}

 function csvToArray($path)
{
    try{
        $csv = fopen($path, 'r');
        $rows = [];
        $header = [];
        $index = 0;
        while (($line = fgetcsv($csv)) !== FALSE) {
            if ($index == 0) {
                $header = $line;
                $index = 1;
            } else {
                $row = [];
                for ($i = 0; $i < count($header); $i++) {
                    $row[$header[$i]] = $line[$i];
                }
                array_push($rows, $row);
            }
        }
        return $rows;
    }catch (Exception $exception){
        return false;
    }
}

convertToArray(file_get_content($filename));

function convertToArray(string $content): array
{
   $data = str_getcsv($content,"\n");
   array_walk($data, function(&$a) use ($data) {
       $a = str_getcsv($a);

   return $data;
