Write the usage of the Fwirte function, a little depressed.

$name = $name [1]; $wei = '. /dow/'. $name. TXT '; $weizhi =fopen ($wei, ' a ') or die ("can ' t open file"); Fwrite ($weizhi, $neirong);

The $neirong is a bit big, and the big upper limit is estimated to be hundred M class.
The second question is: $name is the title of the calling database. When you go to perform a build.
He generates 2 files. One is. txt does not have a file name. The second one is the normal title.
。 A. txt file is less than a file with a normal file name, such as

. txt 4002k
Title. txt 12k

Q: It should only generate 1. Why is it 2? 2 builds are performed. And the strange thing is that I set the $name to the ID number type, he will normally generate 1 files, and the content is normal.

Reply to discussion (solution)

Do not quite understand what you want to ask, generate two files can only be your code deliberately done so.

Set file name For example 1.txt 2.txt he's normal. Generated for 1 files
If the file name is set to Chinese, such as the name of the. txt name 2.txt so he generates 1 more empty filenames.
For example. txt. txt

It's impossible!
You clear the data Catalog, and then you test.

Test with ID to use as file name, no problem.
