如何从txt文件中提取数组。

我使用file_put_contents将数组放入文本文件中。

  Array
   (
[0] => Array
    (
        [0] => AMDSempron 145
        [1] => 860,000
        [2] => 910,000
    )

[1] => Array
    (
        [0] => IntelCore 2 Quad Q8200 2.33GHz 4MB L2 Cache
        [1] => 1,800,000
        [2] => 1,800,000
    )

[2] => Array
    (
        [0] => IntelCore i7-920 Processor (8M Cache, 2.66 GHz, 4.80 GT/s
        [1] => 3,300,000
        [2] => 3,300,000
    )

[3] => Array
    (
        [0] => IntelCoreâ¢ i5-3450 Processor -6M Cache, up to 3.50 GHz
        [1] => 5,600,000
        [2] => 6,800,000
    )

[4] => Array
    (
        [0] => IntelÂ® Coreâ¢ i3-530 Processor  -4M Cache, 2.93 GHz
        [1] => 2,350,000
        [2] => 2,380,000
    )
  }

然后将数组输入到文本文件。

此

file.txt的

    Array
   (
    [0] => Array
    (
        [0] => AMDSempron 145
        [1] => 860,000
        [2] => 910,000
    )

[1] => Array
    (
        [0] => IntelCore 2 Quad Q8200 2.33GHz 4MB L2 Cache
        [1] => 1,800,000
        [2] => 1,800,000
    )

[2] => Array
    (
        [0] => IntelCore i7-920 Processor (8M Cache, 2.66 GHz, 4.80 GT/s
        [1] => 3,300,000
        [2] => 3,300,000
    )

[3] => Array
    (
        [0] => IntelCoreâ¢ i5-3450 Processor -6M Cache, up to 3.50 GHz
        [1] => 5,600,000
        [2] => 6,800,000
    )

[4] => Array
    (
        [0] => IntelÂ® Coreâ¢ i3-530 Processor  -4M Cache, 2.93 GHz
        [1] => 2,350,000
        [2] => 2,380,000
    )
  }

现在我该如何提取？我写了这个代码。

     <?php
    file_put_contents('array.txtl', print_r($data, TRUE));

    $arrtxt = file_get_contents('array.txt',treu);

    //Select Name and Price from array

    $par1= array_column( $arrtxt, 0);
    $par2 = array_column( $arrtxt, 1);

    //Combine Name and Price array
    $c = array_combine($par1, $par2);

    foreach($c as $name=>$price){
        echo 'Name:'.'&nbsp;'.$name.'<br />'.'<hr>'.PHP_EOL;
        echo 'price:'.'&nbsp;&nbsp;&nbsp;'.$price.'<br />'.'<hr>'.PHP_EOL;
        }
      ?>

但是给这个错误：

array_column（）期望参数1为数组，资源在第28行的C：\ wamp \ www \ curl \ index.php中给出

Answer 1

尝试使用以下代码：

file_put_contents('array.txt', json_encode($data));

$arrtxt = file_get_contents('array.txt');
$newarr = json_decode($arrtxt);

print_r($newarr); //this will output an array

您可以稍微修改一下您的文本文件（请注意，PHP＆＃39; s数组创建数组（）函数的名称是全小写的）：

 <?php
 $myArray = array([0] => array([0] => AMDSempron 145
                               [1] => 860,000
                               [2] => 910,000
                              )
                  [1] => array([0] => IntelCore 2 Quad Q8200 2.33GHz 4MB L2 Cache
                               [1] => 1,800,000
                               [2] => 1,800,000
                              )
                  [2] => array([0] => IntelCore i7-920 Processor (8M Cache, 2.66 GHz, 4.80 GT/s
                               [1] => 3,300,000
                               [2] => 3,300,000
                              )
                  [3] => array([0] => IntelCore i5-3450 Processor -6M Cache, up to 3.50 GHz
                               [1] => 5,600,000
                               [2] => 6,800,000
                              )
                  [4] => array([0] => IntelCore i3-530 Processor  -4M Cache, 2.93 GHz
                               [1] => 2,350,000
                               [2] => 2,380,000
                              )
                 );
 ?>

然后，在你要使用这个数组数组的php文件中，只需执行以下操作：

include("array.txt");

和＆＃34; $ myArray＆＃34;在那之后到处都会存在＆＃34;包括＆＃34;，并且已经是数组。
