PHP5中的fgetcsv()函数在Linux上会有一个Bug：把文本字段的第一个字符的高位去除掉了，然后就会产生乱码

看到有人在有汉字的字符串 前加一个 ‘ 或是任意半角符号，让bug将其除掉，不过这样做太麻烦了。最后呢，找来一个模拟fgetcsv功能的函数。

 
function __fgetcsv(& $handle, $length = null, $d = ‘,', $e = ‘”‘) { 
$d = preg_quote($d); 
$e = preg_quote($e); 
$_line = “”; 
$eof=false; 
while ($eof != true) { 
$_line .= (empty ($length) ? fgets($handle) : fgets($handle, $length)); 
$itemcnt = preg_match_all(‘/' . $e . ‘/', $_line, $dummy); 
if ($itemcnt % 2 == 0) 
$eof = true; 
} 
$_csv_line = preg_replace(‘/(?: |[ ])?$/', $d, trim($_line)); 
$_csv_pattern = ‘/(‘ . $e . ‘[^' . $e . ']*(?:' . $e . $e . ‘[^' . $e . ']*)*' . $e . ‘|[^' . $d . ']*)' . $d . ‘/'; 
preg_match_all($_csv_pattern, $_csv_line, $_csv_matches); 
$_csv_data = $_csv_matches[1]; 
for ($_csv_i = 0; $_csv_i < count($_csv_data); $_csv_i++) { 
$_csv_data[$_csv_i] = preg_replace(‘/^' . $e . ‘(.*)' . $e . ‘$/s', ‘$1′ , $_csv_data[$_csv_i]); 
$_csv_data[$_csv_i] = str_replace($e . $e, $e, $_csv_data[$_csv_i]); 
} 
return empty ($_line) ? false : $_csv_data; 
}
