引号字符串中的一个逗号分隔的列表中删除逗号

Question

我有一个字符串

$str = '1,2,3,4,5,"6,000",7,8,9'; 

我怎么能清理到：

'1,2,3,4,5,6000,7,8,9' 

Answer 1

尝试是这样的（对于PHP < 5.3）：

$dst = array(); 
$str = '1,2,3,4,5,"6,000",7,8,9'; 

$state = false; 
$buffer = ''; 
for ($i = 0, $lim = strlen($str); $i < $lim; $i += 1) { 
    $char = $str[$i]; 

    switch ($char) { 
    case ',': 
     if (!$state) { 
     $dst[] = $buffer; 
     $buffer = ''; 
     } 
     break; 

    case '"': 
     $state = !$state; 
     break; 

    default: 
     $buffer .= $char; 
    } 
} 

$dst[] = $buffer; 

print_r($dst); 

Answer 2

http://php.net/str-getcsv

$items = str_getcsv($str); 
$items = array_map (
    function ($item) { str_replace(',', '', $item); }, 
    $items; 
); 

现在，如果你就像你可以再次合并它们一样

$str = implode(',', $items); 

Answer 3

<?php 
$str = '1,2,3,4,5,"6,000",7,8,9'; 
echo $str; 
echo str_replace('"','',$str); 
?> 

Answer 4

使用此：

$str = '1,2,3,4,5,"6,000",7,8,9'; 
$pattern='/"(\d+),(\d+)"/'; 
$replacement='${1}$2'; 

echo preg_replace($pattern, $replacement, $str);
