Question

我正在尝试从PHP多维数组中提取特定数据。

数组是这样的：

Array
(
    [0] => Array
        (
            [0] => Item Code Number
            [1] => Item Name
            [2] => Item Description
            [3] => MSRP
            [4] => Cost
            [5] => Weight Pounds
            [6] => Weight Kgs
            [7] => Category 1
            [8] => Category 2
            [9] => Category 3
            [10] => Category 4
            [11] => Youtube Link
            [12] => Large Image URL
        )

    [1] => Array
        (
            [0] => 1
            [1] => Amazing Magic Set
            [2] => Easy to learn magic tricks
            [3] => 24.95
            [4] => 10.5
            [5] => 0.95
            [6] => 0.43
            [7] => New Items
            [8] => Tricks
            [9] => *New Tricks*
            [10] => All Tricks
            [11] => blank
            [12] => http://www.magicmakersinc.com/images/product/large/0051.jpg
        )
)

我想要做的是在数组中循环并从每个条目中拉出0,1,2,4,6并显示该数据。

这是我尝试使用的：

$keys = (array_keys($csv));             
for ($row = 0; $row < sizeof($csv); $row++) {
    echo "<tr>";
        foreach($keys[$row] as $key => $value) {
            echo "<td>".$value."</td>";
        }
        echo "</tr>";
}

我无法显示任何内容。

我也试过了：

for($i = 0; $i < count($csv); $i++) {
    echo "<tr>";
    foreach($csv[$keys[$i]] as $key => $value) {
        echo "<td>".$value(0)."</td>";
    }
    echo "</tr>";
}

我无法弄清楚我做错了什么。任何帮助都会很棒。

Answer 1

尝试

for ($row = 0; $row < sizeof($csv); $row++) {
echo "<tr>";
    foreach($csv[$row] as $key => $value) {
        if($k == '0' || $k == '1' || $k == '2' || $k == '4' || $k == '6'){
            echo "<td>".$value."</td>";
        }
    }
    echo "</tr>";
}

Answer 2

尝试此代码：

foreach ($row ar $val) {
    echo "<tr>";
        foreach($val as $k => $v) {
            if($k == '0' || $k == '1' || $k == '2' || $k == '4' || $k == '6'){
                echo "<td>".$td."</td>";
            }
        }
    echo "</tr>";
}

Answer 3

使用两个foreach：

foreach ($row ar $tr) {
    echo "<tr>";
        foreach($tr as $td) {
            echo "<td>".$td."</td>";
        }
    echo "</tr>";
}

Answer 4

假设=有

$myArray = Array(
        [0] => Array
            (
                [0] => Item Code Number
                [1] => Item Name
                [2] => Item Description
                [3] => MSRP
                [4] => Cost
                [5] => Weight Pounds
                [6] => Weight Kgs
                [7] => Category 1
                [8] => Category 2
                [9] => Category 3
                [10] => Category 4
                [11] => Youtube Link
                [12] => Large Image URL
            )

        [1] => Array
            (
                [0] => 1
                [1] => Amazing Magic Set
                [2] => Easy to learn magic tricks
                [3] => 24.95
                [4] => 10.5
                [5] => 0.95
                [6] => 0.43
                [7] => New Items
                [8] => Tricks
                [9] => *New Tricks*
                [10] => All Tricks
                [11] => blank
                [12] => http://www.magicmakersinc.com/images/product/large/0051.jpg
            )
    )

您可以使用几个foreach

查看内容

  foreach($myArray as $key1 => $value1){

    foreach( $value1 as $key2 => $value2 ){
      echo  $key1 .  ' ' $key2 .'  value ' .$value2
    }

  }

或特定访问0,1,2,4,6

  foreach($myArray as $key1 => $value1){

      echo  $key1 .  ' ' . $value1[0]  . '</br>';
      echo  $key1 .  ' ' . $value1[1]  . '</br>';

      echo  $key1 .  ' ' . $value1[2]  . '</br>';
      echo  $key1 .  ' ' . $value1[4]  . '</br>';

      echo  $key1 .  ' ' . $value1[6]  . '</br>';


    }

  }

Answer 5

采用不同的方法，将数组合并为第1个作为键，第2个作为值。

//$data is contains your multidimensional array!
$combinedData = array_combine($data[0],$data[1]);

echo $combinedData["Item Code Number"] ; // output 1
echo $combinedData["Item Name"]; //output Amazing Magic Set

//And so on....
