为什么我的 filesize() 方法不起作用？
为什么我的 filesize() 方法不起作用？我的路径适用于 fread() 和 file() 方法，但它不会确认 filesize() 上的路径。为什么不呢？我的正确道路应该是什么？
<?php
$strLessonDescription = fopen("http://nova.umuc.edu/~ct386a28/lovej2ee/exercise5/content/lesson5.txt", "r")
or die ("Error - lesson5.txt cannot be opened");
$lessonDescription = fread($strLessonDescription,
filesize("http://nova.umuc.edu/~ct386a28/lovej2ee/exercise5/content/vocabulary5.txt"));
fclose($strLessonDescription);
echo $lessonDescription;
$arrLessonVocabulary = array();
$arrLessonVocabulary = file("http://nova.umuc.edu/~ct386a28/lovej2ee/exercise5/content/vocabulary5.txt");
if (arrLessonVocabulary == NULL)
print "Error - vocabulary5.txt cannot be opened";
?>
Why wont my filesize() method work? My path works for the fread() and file() methods, but it wont acknowledge the path on filesize(). Why not? What should my correct path be?
<?php
$strLessonDescription = fopen("http://nova.umuc.edu/~ct386a28/lovej2ee/exercise5/content/lesson5.txt", "r")
or die ("Error - lesson5.txt cannot be opened");
$lessonDescription = fread($strLessonDescription,
filesize("http://nova.umuc.edu/~ct386a28/lovej2ee/exercise5/content/vocabulary5.txt"));
fclose($strLessonDescription);
echo $lessonDescription;
$arrLessonVocabulary = array();
$arrLessonVocabulary = file("http://nova.umuc.edu/~ct386a28/lovej2ee/exercise5/content/vocabulary5.txt");
if (arrLessonVocabulary == NULL)
print "Error - vocabulary5.txt cannot be opened";
?>

由于您尝试读取的文件是通过远程请求而不是本地文件，因此它会显着改变您读取该数据的方式。根据 fread() 手册页，您需要分块读取文件。或者，尝试使用 file_get_contents() 这应该简化你的代码：
Since the file you're trying to read is via a remote request, rather than local file, it significantly changes how you want to read that data. Per the fread() manual page, you need to read the file in chunks. Alternatively, try using file_get_contents() which should simplify your code:
