[PHP] problems in extension development
hi, I just started to write a simple PHP extension "hello", but encountered some problems. I followed tutorials step by step: 1. ./ext_skel --extname=hello 2. modified hello.c and php_hello.h, and wrote function hello_world() which simply return a string "hello world". 3. phpize 4. ./configure ; make ; 5. the I encountered error in make. I looked up in Makefile and found that $(PHP_MODULE) is null, which I think is the reason. Makefile is automatically generated by ./configure. What mistake did I make? How to fix it? Thanks!

Re: [PHP] basic captcha
Hi, all When you ask for a captcha, I'd first ask what do you want to use it for. If you read the first lines of Wikipedia it has been developed to differ between a real user and a bot. If you'd now say that you want to use it to protect spam in a formula I'd give you the same explanation that you can find here in german (in a bit more text): http://www.1ngo.de/web/captcha-spam.html The author of this link says that captchas are not efficient enough and give a new unnecessary barrier to all users. He also declaims that bots nowadays are better than ever and can even read captchas that many humans are not able to read. For this reason he provides a list of extra stuff that you can use to protect your formula against spam instead of a picture that's text should be written in an input-field. One of those is the honey-pot. You simply create an additional field (f.e. * email2*) hide it for most visitors (using *css*) and ignore the comment if there's text in here. As most of the bots cannot read css they'll fill a valid email-address in here :) But then you also have to think about users that have css disabled f.e. *ScreenReader*. Another disadvantage of this issue is that you can use an auto-field-fill mechanism provided by the browser who could fill this field ... But both cases should not be that difficult. For the screenreder you can change the label for the field to look like *Do not paste your email in here. Just leave it empty.* Just to have the word email again in here ;) Another good thing is to think about how fast this form can be submitted when the user enters the formula for the first time. Also think about the second time, when the user as entered some wrong values and you have to show him a message. If you have a formula that contains more than 5 fields it's quite unusual that the user can submit that below 2 sec after receiving the response. You could even add a feature by using javascript that the user cannot submit this form or his request will be delayed for a view seconds (one or two). If you want to know more about that, out there are plenty of plugins for different systems where you can see what other possibilities you have. One extension i like is the one from TYPO3. They have quite a bunch of such things and you can give each of the checks a value. If the sum of the values of the failing tests reaches a configured level, this form-submission will be rejected. http://typo3.org/extensions/repository/view/wt_spamshield/current/ Wordpress: http://antispambee.de/ Bye Simon 2012/2/17 Savetheinternet > On Fri, Feb 17, 2012 at 3:40 PM, Donovan Brooke wrote: > > Hello, > > > > Does anyone know of a basic (open source or freeware) form captcha system > > for PHP? > > > > TIA, > > Donovan > > > > > > > > > > -- > > D Brooke > > > > Hi, > > There are plenty of free PHP captcha scripts out there.

If the data is from user input, then this is really dangerous (that's why there is a big fat warning on the eval man page). You can easily execute nasty commands with eval. If it is user input, then it would be much safer to do the parsing yourself.

You were on the right lines with the eval:
$condition = "return 4 < 5;";
if (eval($condition))
{
//do stuff
}
I just added the return statement and the semicolon, because the error
was complaining about it not being a proper PHP statement basically.

The user will be able to construct their own query strings, it's

this:
$condition = "4 < 5";

Can you explain a more clearly what it is you're trying to accomplish? It sounds like you have a string "$x < $y" in the database that you then replace into a string "4 < 5" which you want to test a conditional on.

Hi folks, I've constructed simple conditions based on DB data and would like to actually evaluate them with PHP.

Like I said before, cURL is the way to "interface" with Google. Basically, cURL can be used to request resources, in this case a web page, from the web. You can call a URL and parse the page of results to determine whatever you need to.

A quick search shows that there are some project out there to detect plagiarism, but I think for university calibre there's a hefty sum of money required. To get a rough idea, you could break a text into sentences, and then query each one of those to see if it occurs just like that. You can use cURL to grab search results pages for this sort of thing, no need for a special interface. There are a few things to bear in mind though: * Googles terms and conditions may prohibit using their search engine like this, or may impose a limit on how much you can do this * Some sentences will be intentionally copied, as quotes. Maybe some sort of check against the source to see if it's in a quote context. * What if only part of a sentence is copied? Maybe after you've searched for exact matches from the sentences in the source, you could remove them from the source, then re-check every sentence against Googles fuzzy search. It may produce many false positives though. There are plenty of other factors too, such as students copying from books which don't exist in a search engines archives, some subjects may unintentionally result in the same way of wording, particularly technical subjects which tend to be removed from more creative and flowery descriptive tendencies. -- Thanks, Ash http://www.ashleysheridan.co.uk

You may want to check again. Ever see ^M at the end of your lines? Or, in vim, notice how it says it's a DOS file? > Even better, go Unicode.

Nothing you've suggested is necessarily bad, but more to the point, it doesn't come close to invalidating the benefit of PHP_EOL. -- Network Infrastructure Manager http://www.php.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I don't think it is good practice to use it when writing to files. I often write files on a Linux server that people are going to read on a Windows PC. Apart from that, most software written in the last 5-10 years will happily read files with either \n or \r\n line endings. I'm not really sure about Win XP for example, but if it would have a problem with the Linux \n endings, it might even be better to *always* use \r\n line endings (except where standards require it), as I haven't seen a single Linux application since I started using it (about 9 years ago) that was not able to read a file with \r\n based line endings. Even better, go Unicode. Unicode specifies that there are 8 ways to make a new line, and they should all be accepted. However, the pretty uncommon NEL, LS and PS are not supported in many applications. (though CR, LF and CRLF are). - Matijn -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For systems which use \n, PHP_EOL will be \n. For systems which use \r\n, PHP_EOL will be \r\n. And, for oddball or legacy systems which still use \r you get the point. This means you can rest assured that the newlines will be appropriate for the system on which PHP is running. While it makes little difference on the web, it makes a world of difference at the CLI and when writing to plain-text files (including CSV). I've been using it out of the force of habit for about seven years or so, and exclusively (with the exception of email headers and other warranted cases) for the last four. There are a lot of other very useful and yet very underused constants.

Why the '.PHP_EOL' ?
I've never seen that before and looking through the PHP documentation doesn't
give me much.
