fgetcsvでエスケープされていない二重引用符を解析する

Question

私はCSVファイルをMySQLデータベースにインポートしています。 CSVを解析するには、fgetcsv()を使用しています。 CSVは、「エスケープされていないcharacetersと原因とを含んでいるerror array_combine(): Both parameters should have an equal number of elements

CSVデータはこの形式である：私は追加

function csv_to_array($filename='', $delimiter=',', $enclosure='"', $escapestring='"') 
{ 
if(!file_exists($filename) || !is_readable($filename)) 
    return FALSE; 

$header = NULL; 
$data = array(); 
if (($handle = fopen($filename, 'r')) !== FALSE) 
{ 
    while (($row = fgetcsv($handle, 1000, $delimiter, $enclosure, $escapestring)) !== FALSE) 
    { 
     if(!$header) 
      $header = $row; 
     else 
      $data[] = array_combine($header, $row); 
    } 
    fclose($handle); 
} 
return $data; 

}

：

"GR109  "," ",0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0,0.0," ","GRANT  ","M   ","W",0,0.0,0.0,0.0,0.0,0.0,0,0,0,0,0,0.0,0.0," ",0,0,0.0," "," "," ",2.42,0.0,0.0,0.0,0.0," "," "," "," "," "," ",0.0,0.0,0.0,0.0,0.0," "," "," "," ","SELF COL ","16 P PR. "," ","PLAIN  "," ","R/E1ROW "," "," "," "," "," "," "," ","R/E1ROW ","BEADED "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," ","GRANT  ","GRANT  "," "," "," "," ",0.0," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," "," ","VAMP LNG - BLK. CARAVELLE P/S. QTR. LNG./ TNG.LINING - BLK. TORINO. (GREY ""TORINO"" FOR LIZARD.)","GR109 COMPLETE" 

私のコード$escapestring='"'しかし、それは助けになりませんでした。 ""文字がエスケープされていない "" TORINO ""からのエラーですか？もしそうなら、これらのフィールドを扱う方法はありますか？

Answer 1

Ok。私はそれを見つけたと思う。間違いなくfgetcsvの2番目のパラメータは、ラインの長さであり、ちょっと台無しになっています。単に0に変更してください（機能はかなり遅くなります）、または倍にしてください。 1000だったときは、各行を2行に分けていました.1つは長さがちょうど1000文字（世界の真ん中でさえカットされました）で、2行目は改行文字まで残りの行です。だから、最初の$行変数は再び、その後、約13 117の長さを持つ配列した117と

13.ただ、これを変更：

while (($row = fgetcsv($handle, 1000, $delimiter, $enclosure, $escapestring)) !== FALSE) 

これに：

while (($row = fgetcsv($handle, 0, $delimiter, $enclosure, $escapestring)) !== FALSE) 

Answer 2

あなたのコードは私にとって完璧に機能します。下の例では、サンプルデータにヘッダーが含まれていないため、ヘッダー処理を削除しました。

<?php 

function csv_to_array($filename='', $delimiter=',', $enclosure='"', $escapestring='"') 
{ 
    if(!file_exists($filename) || !is_readable($filename)) 
     return FALSE; 

    $data = array(); 
    if (($handle = fopen($filename, 'r')) !== FALSE) { 
     while (($row = fgetcsv($handle, 1000, $delimiter, $enclosure, $escapestring)) !== FALSE) { 
      $data[] = $row; 
     } 
     fclose($handle); 
    } 
    return $data; 
} 

$result = csv_to_array('test.csv'); 
foreach ($result as $key=>$element) { 
    echo $key . ' => ' . print_r($element,true) . "\n"; 
} 

ファイルtest.csvがあなたの指定したCSV文字列が含まれている場合、明らか出力は（短縮）である：

0 => Array 
(
    [0] => GR109  
    [1] => 
    [2] => 0.0 
    [3] => 0.0 
    // ..... 
    [127] => 
    [128] => VAMP LNG - BLK. CARAVELLE P/S. QTR. LNG./ TNG.LINING - BLK. TORINO. (GREY "TORINO" FOR LIZARD.) 
    [129] => GR109 COMPLETE 
) 

Answer 3

$result = preg_replace('/"((?=[^"]*)(?=(?=[^"]*)))"/', '$1', $subject);

上記の正規表現は、二重の内側に二重引用符を削除します引用符。 これは、との仕事になります。

1. "いくつかのテキストは、 "内部" よりテキスト"

2. "複数のテキスト"

を "内部の引用を" 引用します
