Re: [PHP] fwrite not writing
This function suddenly stopped working, and I just can't seem to figure
out
why. The only change made recently is that now the value of $force at
calltime is sometimes true instead of being undefined or null.
build_file("file_content","/path/to/file.inc","w",TRUE);
function build_file($func_name,$filepath,$mode="w",$force=FALSE)
{
if($force or !file_exists($filepath) or !filesize($filepath)) //echo
filesize($filepath) shows '0'
{
$content=$func_name(); //echo $content shows it's all there
$fp=fopen($filepath,$mode);
fwrite($fp,$content);
rewind($fp); #temp test
$read_back=fread($fp,10); #temp test
echo "pfile content:/p\n $read_back"; #temp test, displays
nothing
fclose($fp);
}
}
I've tried putting echoes and "or die('Error on __LINE__')" on every line,
checked all the variable values, and found no answers from that.
Everything shows exactly as it should be except that the content that
echoes out so nicely *doesn't ever get written to the file*. The function
runs to the end without error and the file's modification date is even
updated. But the file remains empty. I'm probably missing something
ridiculously obvious, but would someone please be kind enough to point out
what it is? Thank you!!
What is this:
!filesize($filepath)
If filesize is zero (which it is groan), then do the rest (which it
does--except the content it fetches never makes it into the file it writes
to. How that can be, I dunno, but that apparently is what it's doing...)
Add this above your if loop:
$filesize = filesize($filepath);
echo $filesize;
Already tried echoing that and all the other values. Filesize is 0.
That might be causing your loop not to execute...if not, I'm not sure what's
wrong.
I don't get it. It should work. It did work. Suddenly it's not.

Re: [PHP] fwrite not writing
Ahhh, I see what's going on now. I had more time to read over the code, so
now I see what you are trying to do.
I'm not sure why it suddenly stopped working, but let's see if you actually
need it to work.
First of all, I take it that you have content which you want to write into a
file. Correct?
If so, why does it matter if the file you want to write it to has data
anyway? If you are just going to add data into it, isn't it ok that it is a
zerolength file?
Or is the problem that the file is _not_ actually zerolength, but PHP says
it's zerolength anyway?
Just try removing the !filesize() part, and then try executing the function.
But maybe I just don't understand what you are trying to write and why.
Could you be a little more specific what data is being saved in the file,
and what is in the file already?

It is needed. I have a dynamically generated page. Most of the content
needs to be re-generated with every request. But some of it needs to be
re-generated far less often. Rather than unnecessarily hit the db every
time to get the exact same content, that content gets cached to an include
file. This function checks whether that file needs to get a content
refresh, and if so rewrites that content. (I'm not adding data to the
file, I'm overwriting it.)
Or is the problem that the file is _not_ actually zerolength, but PHP says

Nope, it's really zero length. The filesystem agrees with PHP, and when I
open it in a text editor the file is empty.
Just try removing the !filesize() part, and then try executing the function.
I commented out the entire if() condition, it makes no difference. Maybe I
have not made this clear enough: the problem is not in getting inside the
loop. The function *is* executing the loop, and *is* reaching the fwite()
line as well as continuing without error past that line. The frustrating
part is that fwrite() is writing an empty string to the file instead of
using the $content variable (which, when echoed immediately before that
line, is definitely not empty/null).
But maybe I just don't understand what you are trying to write and why.
Could you be a little more specific what data is being saved in the file,

Sometimes the file has data, sometimes it doesn't; sometimes the file
exists, sometimes it does. Right now, unfortunately, the file remains
empty. I'm trying to fill it with a large block of dynamically generated
HTML which will then be used as a static include file for current and
subsequent requests.

Re: [PHP] fwrite not writing
if($force or !file_exists($filepath) or !filesize($filepath))
May I suggest
if ($force || (!file_exists($filepath)) || (!filesize($filepath)))
Probably won't make much difference, but I've never used the "or"
clause and cannot vouch for it's effectiveness.
Also, put a check in after the fopen() call and make sure you're
able to open up the file correctly.
Perhaps and fflush() call before the rewind() call to ensure that
the file buffer's actually written to disk before you try to re-read it?

Checked, and no. The file is being included. It just doesn't have any

C)Do you have the required permissions for write access and for including

Permissions: yes (the file is updating, just with the wrong content)
Including: yes (it's in the include path too)
I've also checked that no other fuction is writing to the same file and
that the function is not recursing (to, say, write the correct content on
one pass then overwrite with empty string on the next pass). No to those
too.

Re: [PHP] fwrite not writing (simpler example), PHP 4.0.4pl1, Apache/1.3.14

come to think of it, why are you passing 3 arguements to fwrite()?
Whoops! That's a typo left over from the last round of tests, adding
every optional argument just in case something wasn't really optional. Of
course the third argument actually belongs to fopen(). Though it shouldn't
be needed there either. (And yup, I just double-checked and it doesn't
work without the typo either. sigh)

[PHP] fwrite not writing
This function suddenly stopped working, and I just can't seem to figure out
why. The only change made recently is that now the value of $force at
calltime is sometimes true instead of being undefined or null.
build_file("file_content","/path/to/file.inc","w",TRUE);
function build_file($func_name,$filepath,$mode="w",$force=FALSE)
{
if($force or !file_exists($filepath) or !filesize($filepath)) //echo
filesize($filepath) shows '0'
{
$content=$func_name(); //echo $content shows it's all there
$fp=fopen($filepath,$mode);
fwrite($fp,$content);
rewind($fp); #temp test
$read_back=fread($fp,10); #temp test
echo "pfile content:/p\n $read_back"; #temp test, displays nothing
fclose($fp);
}
}
I've tried putting echoes and "or die('Error on __LINE__')" on every line,
checked all the variable values, and found no answers from that.
Everything shows exactly as it should be except that the content that
echoes out so nicely *doesn't ever get written to the file*. The function
runs to the end without error and the file's modification date is even
updated. But the file remains empty. I'm probably missing something
ridiculously obvious, but would someone please be kind enough to point out
what it is? Thank you!!
