My system unfroze itself yesterday night, the drive in question can copy a 100mb file at regular speedy speeds with windows explorer, but writing 45mb of html to a file using (thousands of) fwrite() calls takes about 10 minutes (bit slow to say the least). The same fwrite()ing code on my hosted server, with nearly as much html to write out, works comfortably fast as well. I'm very puzzled.

Aren't these startup errors? I am not quite sure, but if the y can't be
handled with php.
This is from the PHP docs
"The following error types cannot be handled with a user defined function:
E_ERROR , E_PARSE , E_CORE_ERROR , E_CORE_WARNING , E_COMPILE_ERROR ,
E_COMPILE_WARNING , and most of E_STRICT raised in the file where
set_error_handler() is called.
If errors occur before the script is executed (e.g. on file uploads) the
custom error handler cannot be called since it is not registered at that
time."
So the only thing you can do is have a watchdog on your phperror.log and
dosomething if these errors occur.
To preparse syntax errors you can use find and php -l
$ find . -name "*.php" -exec php -l {} \;

Regards Ashwani Simply put: the email account you have created is being ignored by the mail() function. It doesn't matter if you created an email account or not; if I wanted to, I could make mail() send emails from presid...@whitehouse.gov or from kofi.an...@un.org. The mails would never appear in their outboxes, simply because an outbox or sent mail folder is a local copy of your mail, made by the mail client. It has nothing, intrinsically, to do with emailing anyone. If I try email someone, this happens: 1. I load my mail client 2. I type my mail and press send 3. My mail client stores a copy of this mail in the sent folder 4. My mail client contacts the server, and tells it that it has a mail from me, to a certain adress, and then hands it over. 5. My mail client tells me "mail sent successfully" If I use PHP's mail function, the following happens: 1. The PHP script is ran 2. The mail() function is invoked with the email message to send as a string 3. The mail() function starts up a local program called sendmail (or a program which does roughly the same thing), which it then gives the entire message to send to. 4. sendmail contacts the server, and tells it that it has a mail from me, to a certain adress, and then hands it over. 5. the mail() function says "mail sent succesfully" So, as you can see, the storage of the email in the sent box has nothing to do with actual sending of the mail, but purely with the use of your mail client, which PHP does not use (obviously). If you really do want to store the email, you'll have to do it yourself. "admin" (which is an annoying nickname on the internet!

I've kinda run out of ideas, besides ofcourse serving slightly different stats and graphs for non-developer viewers, and the error details only to developers. That one's obvious. And another obvious one, I also think that plugging in location software by http://www.maxmind.com/app/geolitecity will be a good idea, altho I'd probably opt to work with their data in a sql table rather than the faster php mod that they offer, coz we can't use that from shared hosting (I think, plz correct me if I'm wrong).

I thought putting many scripts in 1 call was the right thing to do.

You hit upon a theory of mine -- and that is our functions grow in size up to our ability to view them in their totality. When our functions get beyond that limit, we tend to refactor and reduce. I know from the last several decades of programming, my functions have increased in number of lines. But, they have reached a limit that limit is generally about the number of lines I can read in half of my monitor's height. This of course, is dependent on monitor resolution, font-size, and how far I am sitting from the monitor. But I think this is a natural and physical limit that we don't normally recognize. I can cite studies that support my theory. It would be an interesting survey to ask programmers to review their code and provide the average number of lines in their functions AND how many lines of code their monitor's can display. In other words, look at your editor; count the number of lines your monitor can display; estimate the number of lines in your average function; and report the findings. For example, mine is about half -- my monitor can display 55 lines of code and my average function is around 25 lines. YMMV. Interesting, yes?

This can be a particular issue if you're writing 404 handlers or anything that relies on query strings. In particular you need to test and check for differences between Apache and IIS in how the REQUEST_URI, QUERY_STRING, URL, and ORIG_PATH_INFO variables are populated depending on whether your script is being called directly or as a 404 handler. When redirecting due to a 404 or some other redirect or error IIS will populate some variables with values like this "/404.php?404;http://www.server.com:80/blah.php?v=1&t=2"; whereas Apache will populate the same variable with "/blah.php?v=1&t=2" in the same situation. This means the query string needs to be parsed differently.

Just to clarify on this point, Windows (or rather NTFS) permissions use full ACLs and so, for each file system object, any number of users and/or groups can have any number of allow or deny permissions assigned to them for a range of activities (e.g. read, write, append, delete, create, execute, traverse, read/write attributes, read/write permissions, etc.). There's a good article here that begins to explain it: 'Understanding Windows NTFS Permissions' http://www.windowsecurity.com/articles/Understanding-Windows-NTFS-Permissions.html NTFS ACLs are similar to (not not identical to) Posix Access Control Lists that are available for Linux and Unixes. -- MarkR PGP public key: http://www.signal100.com/markr/pgp Key ID: C9C5C162 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No problem, I get a valid signature which I then base64 encode and store in a database. Now lets say a couple of days from now I load up the public key which corresponds to the private key which was used to originally sign the data to verify it and it does not work. The kicker is if I perform the very same routine without saving the signature and attempting to verify it it works without problems. Example script: /* this part works */ $id = openssl_pkey_get_private($key, $pass); openssl_sign($unsigned, $signed, $id); $id = openssl_pkey_get_public($pub); openssl_verify($unsigned, $signed, $id); /* this doesn't (here I use the existing signature instead of generating a new one) */ $id = openssl_pkey_get_public($pub); openssl_verify($unsigned, $signature, $id); /* below here is all of the existing variables the above uses */ $unsigned = "w9A5Tt8JA/GVBn89WwpvXnnVsHvyWbEDu5GdX36m+ZQ=:ek4L55qc/VKAmiYdlIQhow==:ek4L55qc/VKAmiYdlIQhow==:6IraS+ArqK+/Yc472tfFqmhk5VdIACUQPCR7+kbLoAEldjejS/P1cSa8EMHxcV2s:50dt57IoKeQZ7eiwoILMR3E91MtbCgt+xVn483+9J1cNzBQGll02Qj40RVhNM/Rh:qEFBUlZzNYZNb7nksj8Fhd8Du52RVDjMBwoT/O0tdzKGfGVOeK2xrpuq1OdoAo2CN63U+Fra4zcfkzwkD3QxDA==:1337713224" $pass = "$2a$07$31a9f929d102f5f0374deuu.cfoTJbmZtGKk92CuAOP63XaRUAVIW"; $signature = "h+SdcyxuQ9kpb2CXZRA/grJjlYj+drlOH2f7Ifsnt5A8dSj9lkMYU11rtjT9sdaEhf3rvoIl9JUMvkzc6dJ4DMypqgGniqbesbK6yf30FmPd0an+bTyIpeQFasmUwxtB1y6wBjIENEzEDTyb6QHPTAZg6ep2m/NjZFfUn/iiDOnDt71KQD1whouwtRZ0+UcDfPvtLQ3bAGw9C5ThDoIHRlg1kzVLrq40QsjA/3zYJE+PKwG9i1srI8zbP6uW/0t6mnUpGQrZmz6sdekkdCjjc7R9bIsFdyZ2Gisr6W1pBH64/X4nGaDkYX99ss8vYfuQMp+fLyZGgEKXuAwHjT02iQ=="; $key = "-BEGIN ENCRYPTED PRIVATE KEY- MIIFDjBABgkqhkiG9w0BBQ0wMzAbBgkqhkiG9w0BBQwwDgQIgeRB2NhoaJgCAggA MBQGCCqGSIb3DQMHBAgk9XLQVrN2UQSCBMgNQWJWdwpXarX8Do5xPGSdEw526jai XlvAR0lX4QzkKGnx1Fe13r0Z7AwGsEyuZWhmiQTeL40sBGtKpqdwr3Eutj+W02Kg 7jlBcgeu5DnYeQHZ6kDUJD4o08LXtDlusTIjsVLOE0YtLA67M7X2GSJrCUOurW/r nPTYGwNt9Z59jtB/EwPqa7kxvhPF0OTZ/6+5NRmWczPnF5KAltLaH0PsR6JI9y9K ben/SZ6QYp4PTVva5HNDBXS2sYAW9AynA7ltEOzXtWTLK2SLcGsVuqWM/WBiTyKw MeRDPA4y6MwJDUuUvZNzNAi9FXy8c10shGSJBHyP4xBrn6DTEXEIrrsGhePRaCB1 GaH26K/q6yxq1HJdRttexHMK7GCyH325ufHT4Fup+FaJqkC0nAK6uuMbCqML4feC K73OVzCF9Sh2o43aaJR3Ktec5ACqW7SDSABirJMU+YQpE9Dyei5d6mo+3E1rulVr 7dfsjeLmJGx5SDf8ip+tEGj4VcVm48w7hWFAmi1KAif8YLbvFEaWwTYhJg0qrCPI eQuFVR8k6EDhGMKs2KnrfkUUhU4riosbryXACB1fi/oHmJmYAEBiYgFhYgwsNX/O QRqedbIPDYcTfCb/j0Z59kkN9Il5YuanzPvaU6zWDMBy6qo1SYdM0lstWH7RJodq eg/WAvKq1zwBPLoedt32UgTgHioQe4r8rVTwmQd0kFAVN+mdsdCtn7xCFliul042 n7bYWtVwiLeXecSOoY0G/0oJ7MhgddAbD9CJlLMoMmM669V+xQldoE0FKQUbrr3W vqOIoBWp1Bd8mQ0FHn5yn/blYYy0sgCEkuSvR+NqgBt620qJ+x7kIpnay9+tdDun v8bXz4gonA8+MGyf3yjwVNR6elZMGH/SxK1dQn65lK1AsPFKTHy+2TC5UgBw1zhe +DjkKkilgsL3TaIKIxr/aDctqja9PfxiZek5GkDRuJN1rk3StW75hpnCyJdIQYXo q4mpdR7MYfknH7l8hsMBGYhDJNQ2iBJ/HZag4FWl2GWRQcqlJ0cZOWST+inMCTs5 UhEKYQoifKpZGLZ9vFUC1U6jiJ5SMmHp8LlEW4XlX1fbpYWU4xiLXjrCgATW9eLE Af3/q0bqBKggjNLqI4ShXjzBhExRKlVOceWxO2PJUzBKYkmENJ3oV1ykuPFp2cwO 2jhmMvCIL9ja3d8xQXc/WbCkmKOIm94PvAT7SmZksf7tvKNlhRrKS53ncGyWxhNp VwRtxQq/VnKJvyXWjImqE4bIeh3Ca1kzVoO0fmSS1la42hRXoXOlFOC59i3P9Tfs qazgCepsMB+PfRoiarnxCRrTHunnExbNw+0aCWR8J0B6X9jTyfbga6dTNNqJvHBI ffp9R9tDd+3trwC7RNbCLSv8E6qRKiNM1kv4UhP4avn0J21wnB0fjz32PASrArNe NCauY0+sSCwrE03nDhdt4NUhylAa6JTJZwQlNM6zwt7ITBOnVTQh0EoZl+fJRN9f QROdqPuvJUHaO1UbL05cm9bqpovs7+vn2UxkpMTkQ/lyS8Vfl5DbqX6dCKz3/3pP KK7LjZegt9Ey2wZB/9OiKGyOPiXPwzXcXR/evC6TFeIA07/8018PRjdjefZV26c4 M4g= -END ENCRYPTED PRIVATE KEY-"; $pub = "-BEGIN PUBLIC KEY- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAyEFetjn8mpkqHTgtKATK Gu7dgG6UXHD+Ft8UO6WoWgVGhnjgk+SlNI+4RG9BvCaG4jbPueu4nb15oO4aObQg RXZ7el2gjgEYu90qRILsDSzouoGFc/qPe6tNOUZ/ZXR3kBTm9t3CAW4bNDsnfUnP YFQVdFco03Pbz8vejc0SVSC8l2lw+ZSkMYDzDmhv09Uk1zh1kc/ACOU0AoofEaUM 2eyekwcQiVwzKksGjW70eOuI2QtgpIwuvQSS/BAcymYKkxJZVxUMPCwdBwY+Pyo+ +lD4yGeki0E7x72uQy0bzulxa6iXhQOYFQEcShxyJEF6YN/R/XSIQBLTi9biWvGg 6QIDAQAB -END PUBLIC KEY-"; -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Or, if your mail server has IMAP access, use any PHP IMAP extension
to connect to your IMAP server and send it from there. Then it will
appear in your outbox.

Are you sure? I connect to my email through Imap on both my desktop and
my phone, and neither sees the others sent emails. I thought sent was
just a local thing, unless the email client is specifically configured
to do something special.

Generally I'll split a function if I'm reusing more than a couple of lines of code. I only split a "large" function if it's actually doing several things, if it happens to need 200 lines to perform one 'step' then I'll leave it as is. While I do prefer my functions to fit into a single 'screen', it rarely happens quite like that, because I move from screen to screen with different resolutions, so there's no constant limit for me. As a rough example, on a random selection of 27 functions taken from a controller on a site I worked on I get these general statistics: Functions: 27 Mean lines: 22.5 Mode lines: 3 Max lines: 218 The function with 218 lines is a large switch, and it doesn't make sense to do it any other way, because it would actually end up less readable. -- Thanks, Ash http://www.ashleysheridan.co.uk

Though, it is unavoidable in some cases I think. I do have some of these functions in my code too, I have one switch block of more than 500 lines, but that's just because I have more than 400 individual case statements, and I don't think there's a better way to do it.

Yes, I have a few applications that send email through IMAP and they end up
in my sent mail box. Both with this Gmail account, and a mail server on a
different host. You're clients are probably configured to still use SMTP
for sending, not IMAP.

Doesn't mean I like it btw. I never encounter such big switch statement in PHP yet. However I saw huge switch and had to optimize it while working with a custom programming language interpreter written in C. When I see the language is OO, I try to apply polymorphic behavior and eliminate any switch statements.

Re: [PHP] Function size
I use a lot of switches but they are always small in size because they look
mostly like this:
switch($action) {
case 'hello':
$someObject->executeAction();
break;
case 'world':
$someOtherObject->executeOtherAction();
break;
default:
$this->anotherAction();
break;
}
Maybe it's not the rule for some really specific small functionality which I
know I won't be using ever again, but that's the latest trend I've acquired in
order to improve readability. Personally I find that the particular switch
statement disorders the code, but at least it is a lot better than a lot of
if/elses xD
Haven't you tried this approach or does that particular function do have a lot
of cases?
Greetings.

You hit upon a theory of mine -- and that is our functions grow in size up
to our ability to view them in their totality. When our functions get
beyond that limit, we tend to refactor and reduce.

This is because the rule of thumb I follow is that a function should do one thing, and should be named well. The biggest downside to the type of style I have is that if not done "correctly", people can feel like they're swimming in a sea of chasing down functions to find out wtf is going on. When done "correctly", it leads to pretty clear code, IMO. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
