PHP的foreach回声照片和QUOT;数组＆QUOT;作为价值 [英] php foreach echo prints "Array" as value

问题描述

也许我根本无法理解PHP如何处理数组。

Perhaps I'm simply having trouble understanding how php handles arrays.

我想打印出来使用foreach循环数组。所有我似乎可以摆脱它是单词阵列。

I'm trying to print out an array using a foreach loop. All I can seem to get out of it is the word "Array".

<?php 
    $someArray[]=array('1','2','3','4','5','6','7'); // size 7
    foreach($someArray as $value){ 
        echo $value;    
?> 

<br />

<?php
    }
?>

本打印出来的：

Array

我无法理解为什么会出现这种情况。如果我定义数组前面像上面，它会打印出阵。它几乎好像我有手动定义一切......这意味着我必须做一些错误的。

I'm having trouble understanding why this would be the case. If I define an array up front like above, it'll print "Array". It almost seems like I have to manually define everything... which means I must be doing something wrong.

本作品：

<?php 
    $someArray[0] = '1';
    $someArray[1] = '2';
    $someArray[2] = '3';
    $someArray[3] = '4';
    $someArray[4] = '5';
    $someArray[5] = '6';
    $someArray[6] = '7';

    for($i=0; $i<7; $i++){
        echo $someArray[$i]."<br />";
    }
?>

为什么不能在foreach工作？

Why won't the foreach work?

推荐答案

您没有正确申报的数组。结果
你要删除的方括号： []

You haven't declared the array properly.
You have to remove the square brackets: [].

<?php 
$someArray=array('1','2','3','4','5','6','7'); // size 7
foreach($someArray as $value){ 
    echo $value;    
?>  <br />
<?php
}
?>
