将键值从文件插入到 PHP 中的关联数组


insert key-values to associative array in php from file

我无法将文件中的值插入到php关联数组中。谁能帮忙?代码如下,查看第 3 个数组项,我想从文件中插入键值,但每次我都收到 en 错误。怎么做?(包含、回显或函数结果 - 在数组中不起作用!怎么做?

<?
$somedeclaredvaiable = '0 => "value1", 1 => "value2", 2 => value3", 3 => "value4", 4 => "value5", 7 => 4';
$a = array(
1 => array(
   0 => "value1",
   1 => "value2",
   2 => "value3",
   3 => "value4",
   4 => "value5",
   7 => 4
),
2 => array(
   0 => "value1a",
   1 => "value2a",
   2 => "value3a",
   3 => "value4a",
   4 => "value5a",
   7 => 4
),
3 => array(
//THE PROBLEM IS HERE, can't include file, or echo an variable!
include 'filewitharray.txt';  //doesn't work
echo $somedeclaredvariable ;  //doesn't work
),
);
?>

这部分代码在语法上不正确:

3 => array(
//THE PROBLEM IS HERE, can't include file, or echo an variable!
include 'filewitharray.txt';  //doesn't work
echo $somedeclaredvariable ;  //doesn't work
),

假设filewitharray.txt是一个 php 文件,它将返回一个数组(或其他内容),如下所示:

<?php
    return array('foo' => 'bar');

然后,您可以执行以下操作:

$a[] = require 'filewitharray.txt';

它会将 filewitharray.txt 返回的变量添加到表中。

如果filewitharray.txt不应该是PHP代码,并且您希望将文件的内容添加到数组中(作为字符串),那么您可以执行以下操作:

<?php
$a[] = file_get_contents('filewitharray.txt');

现在就试试吧。

<?php
  include 'filewitharray.txt';
    $somedeclaredvaiable = '0 => "value1", 1 => "value2", 2 => value3", 3 => "value4", 4 => "value5", 7 => 4';

    $a = array(
    1 => array(
       0 => "value1",
       1 => "value2",
       2 => "value3",
       3 => "value4",
       4 => "value5",
       7 => 4
    ),
    2 => array(
       0 => "value1a",
       1 => "value2a",
       2 => "value3a",
       3 => "value4a",
       4 => "value5a",
       7 => 4
    ),
    3 => array(

    ),
    );
    ?>

首先,事先获取文件的内容:

$included = file_get_contents("file with array.txt");

然后在数组声明中:

...snip
3 => array(
    $included, $somedeclaredvariable
)
);
