如何提取qr代码内容并将其作为数组存储在php中？

Question

我有这个qr代码内容，我使用QR扫描仪Web应用程序提取。以下示例。

例：

// This is the string extracted from the QR Code
"Name1","Name2","Name3","Name4","Name5","Name6","Name7"

当我提交它存储到我的数据库中时，我已将它分配给变量

PHP

<?php
  if(isset($_POST['submit'])) {
    $qr_results = $_POST['qr_bookingresults'];
    $array_results = ltrim($qr_results,"QR Code:"); // I used ltrim because there is a string QR Code: attached when I extract the qr code

    echo $array_results;

  }


?>

但是当我使用print_r function()时，字符串只存储在一个数组中，如下所示：

$fetchresult = array($array_results); // Assign variable and convert $array_results variable to an array
print_r($fetchresult);

print_r（）函数结果

Array ( [0] => "Name1","Name2","Name3","Name4","Name5","Name6","Name7" )

我的问题是，为什么它只将整个字符串存储到一个数组中？其中应该是这样的。

Array ( [0] => Name1 [1] => Name2 [2] => Name3 [3] => Name4 [4] => Name5 [5] => Name6 [6] => Name7 )

因为我真正想做的是提取内容并将其存储到一个数组中，这样我就可以自由地将它插入到mysql中，如下所示：

// Assign each variable to an array for inserting into mysql
$name1 = $fetchresult[0];
$name2 = $fetchresult[1];
$name3 = $fetchresult[2];
$name4 = $fetchresult[3];
$name5 = $fetchresult[4];
$name6 = $fetchresult[5];
$name7 = $fetchresult[6];

有谁知道如何解决这个问题？谢谢

这似乎是一个CSV格式的字符串。

使用str_get_csv()确保您考虑任何文本内逗号和转义引号。

<?php
$qr_string = '"Name1","Name2","Name3","Name4","Name5","Name6","Name7","I am here to ruin your day, am I not?","24"" (inch) TV"';

$array = str_getcsv( $qr_string );

print_r( $array );

结果：

Array
(
    [0] => Name1
    [1] => Name2
    [2] => Name3
    [3] => Name4
    [4] => Name5
    [5] => Name6
    [6] => Name7
    [7] => I am here to ruin your day, am I not?
    [8] => 24" (inch) TV
)

你需要用,.use explode拆分字符串

Sandbox

$a = '"Name1","Name2","Name3","Name4","Name5","Name6","Name7"';
$arr = explode(',',$a);
print_r($arr);
