我编写了一个程序来定义一个名为$aFilter
的关联数组,并尝试打印它,但我无法做到。我尝试了两种方法来实现这一目标但却无法成功。以下是我尝试的两种方式。
方式1:
<!DOCTYPE html>
<html>
<body>
<?php
$aFilter = Array
(
['pages'] => 1,
['photo'] => 1,
['link'] => 1,
['event'] => 1,
['friend'] => 1,
['user_status'] => 1,
['poll'] => 1,
['quiz'] => 1,
['market'] => 1,
['apps'] => 1
)
print_r($aFilter);
?>
</body>
</html>
方式2:
<!DOCTYPE html>
<html>
<body>
<?php
$aFilter = Array
(
['pages'] => 1
['photo'] => 1
['link'] => 1
['event'] => 1
['friend'] => 1
['user_status'] => 1
['poll'] => 1
['quiz'] => 1
['market'] => 1
['apps'] => 1
)
print_r($aFilter);
?>
</body>
</html>
执行上述两个代码后,我的屏幕显示空白。没有任何错误或警告。为什么会这样?如何在不对php.ini文件设置进行任何更改的情况下在网页上显示错误和警告?
有人可以纠正我正在制造的错误并帮助我吗?

在定义数组后忘记了;
。
并且在定义数组时也不要使用[]。 More info on array's.
$aFilter = Array(
'pages' => 1,
'photo' => 1,
'link' => 1,
'event' => 1,
'friend' => 1,
'user_status' => 1,
'poll' => 1,
'quiz' => 1,
'market' => 1,
'apps' => 1
);
print_r($aFilter);
print_r()以人类可读的方式显示有关变量的信息。 这不是您需要编写的代码。

在数组定义之后,两种方式都缺少;
,而方法2在每个数组元素之后缺少,
s。此外,两种方式都应使用'elName' => 'elValue',
而不是['elName'] => 'elValue',

问题是: -
所以这样写: -
Sub Unzip()
Set fso = CreateObject("Scripting.FileSystemObject")
For Each f In fso.GetFolder("C:\Users\Jimbo\Documents\Process\_ThisWeek").Files
If LCase(fso.GetExtensionName(f)) = "zip" And Left(f.Name, 3) = "Health" Then
Unzip f.Path, "C:\Users\Jimbo\Documents\Process\_ThisWeek"
End If
'If the extraction location does not exist create it
Set fso = CreateObject("Scripting.FileSystemObject")
If NOT fso.FolderExists(f.path) Then
fso.CreateFolder(f.path)
End If
'Extract the contants of the zip file
set objShell = CreateObject("Shell.Application")
set FilesInZip = objShell.NameSpace(f.name).items
objShell.NameSpace(f.path).CopyHere(f.name)
Set fso = Nothing
Set objShell = Nothing
Next
End Sub
