<0> hawkaloogie: ?
<1> you're actually asking this?
<2> lol
<0> Yes, i cant find any document on how to calculate, this.
<1> a percentage is a ratio out of 100
<1> because this is a basic math skill
<1> like adding and subtracting
<3> oh boy
<0> Yes, but how can i put this to work with php....
<4> yes,it is eash
<4> easy
<1> well... if you have 100 people polled, and 40 said yes, then 40 / 100 said yes
<1> so 40%
<1> so if you have 20 people polled, and 2 said yes, then 2 / 20 people said yes, so 0.10 or 10%
<0> yes, but how do i take this in to php? i have been searching for a "tut" or a documentation about this.
<1> okay, now you're basically telling me you don't know PHP at all
<2> x1/total * 100
<1> luckily, neither do i
<1> would it be print(x1/total *100); or echo(); ?
<4> i think you must read doc in www.php.com
<3> I can't believe you people are seriously answering this
<1> it's fun!
<2> echo $total==0 ? "div with 0 not allowed" : $x/$total * 100 ."%";
<5> when I'm in a cl***, how can I call a function from the parent cl***?
<6> parent::foo()
<5> thx
<7> you can use the name of the parent cl*** aswell cant you?
<6> self, parent etc work better
<6> -> if you refactor and rename your cl***es, your code doesn't break
<7> yeah of course, just suggesting more options
<8> hi can i use " ^[0-9]*\.[0-9]* " to match 234.45 ?
<9> have you tried?
<8> not yet
<8> :-)
<9> then try it
<9> :-)
<10> nandan: sure, but it would also match "."
<8> codethief: i need to match dot also
<10> dunno whether this side effect is desired
<10> than it should work properly
<11> nandan + is 1 or more matches * is 0 or more.
<10> *than = then
<10> @row: "<8> codethief: i need to match dot also"
<12> Is their a php command that will allow the code to read the name of the file?
<12> like i had randomname.php can i get a php command to read the file name is randomname.php?
<13> I everyone, the company I work for encode their PHP when we deploy. The thing is we have a number of XML files that are used for configuration. At the minute we are thinking of using a script to convert our XML to PHP arrays but that sounds rubbish to me. Is there any way I can encode XML?
<3> "encode"?
<3> what's the -point- of storing data in XML if no one but your software should be able to read it?
<13> because we need to read and change it mst
<13> but our customers shouldn't
<3> well, disregarding my personal feelings towards such an idea, you have pretty much everything available to you, including mcrypt
<14> hi, im using file_get_contents() to read a large file (300MB) into a string. but i only want the last 64KB of the file. i used offset with filesize - 65000, but i still get memory usage > 64MB errors
<14> what am i doing wrong?
<3> use fopen/fseek/fread
<15> How do I check a string for whitespaces?
<14> mst: but isnt offset meant to skip x-bytes ?
<14> why does php still tries to read the whole file?
<13> mst: I'm not keen on it either but I'm new to the job :) , I'll check out mcryt though. Thanks
<15> I need to make sure that my string doesn't contain spaces...
<14> beruic: use str_replace
<14> $string = str_replace(' ','',$string);
<3> fluffles: because it's file_get_contents, the whole point and performance benefit of which is to read the whole file, buffered
<14> mst: so why is the offset there? :(
<14> *spanks php*
<14> anyway, ill try the other functions
<15> fluffles: I need to have a TRUE or FALSE returned...
<13> beruic: use a regular expression
<13> p_reg_match or something
<14> beruic: use strpos ?
<15> themoves: Isn't there a way the uses less lines? and I'm not good with those yet...
<14> will return false or an integer, if integer you need to convert to boolean true
<3> beruic: return preg_match('/ /', $string);
<3> how much less than that do you really need
<15> fluffles: I'll take a look at it ...
<13> less lines? er, if(p_reg_match('/ /', $string)){, beruic one line!
<15> mst: if(my test)
<14> mst: regexps arent for everyone.. :(
<3> if (preg_match('/ /', $string))
<14> personally i hate regexps, but i love their strength :)
<15> Thx guys :)
<3> regexps are the duct tape of the internet
<15> I feel the same way fluf :)
<13> beruic: they are easy!! Read a few tutorials and you'll see the power and love them
<13> They don't need to look like line noise to be useful
<15> themoves: Time my friend... So esseintial. Maybe next month :-P
<13> beruic: indeed. Good luck
<16> hm
<16> I've never done regexps
<17> hello everyone in the awesome php channel
<12> Dont worry, workd out my problem
<17> is there any way I can set a variable in a script when I call it from the command line?
<12> $filename = "subdir/" . $path_parts["basename"] . ".txt" ;
<15> Think I go for the regexp, then I can chack for other characters too :)
<15> Then I should use if(p_reg_match('/[!"#%&/()=?@${[]}|+]/', $string)), right?
<12> Did u still include your space in there?
<12> I thought thats what you were looking for in the first place :/
<15> You are right. Stupid me :)
<15> Can anyone see any mistakes?: if(p_reg_match('/[ !"#%&/()=?@${[]}|+]/', $string))
<3> p_reg_match() is not a real function?
<13> shiznatix: argv
<15> it's should be preg_match :)
<15> Now then: if(preg_match('/[ !"#%&/()=?@${[]}|+]/', $string))
<3> quote the [s
<15> ?
<3> you can't have [ asasdsd[asdasd]adasd]
<15> Show me...
<6> \[\]
<15> Ah...
<15> Shouldn't a space be \s too?
<15> So it's: if(preg_match('/[\s!"#%&/()=?@${\[\]}|+]/', $string)) or what?
<18> hello room i have been building a blog from scratch www.hertfordtown.info/blog.php
<18> can any one help me work out how to put pictures in the entries
<18> i know i need a folder on my server for the image
<18> and a field in the db to record the url to the file
<18> but havent got a clue how to code it really
<19> I have a file name stored in a blob field as : ../../images/ddc/file.txt ! aslo this file is existing on a folder under /images. When I delete it I receive some error ! I get the file name from table by : $file = addslashes($row["DOC_FILENAME"]); and than I try to unlink with : if (unlink("\"".$file)."\"") but I receive an error even if the file is deleted ! anyone know why ?
<20> ace_me: here's an idea, tell us the error message?
<20> ace_me: I find it hard to believe that wasn't obvious
<15> What's wrong?: if(preg_match('/[\s!"#%&/()=?@${\[\]}|+]/', $string))
<19> [function.unlink]: No such file or directory in D:\X_Site\project02\prog\admin\uploaddocumentation.php on line 39
<20> ace_me: ... okay so the file you're trying to unlink doesn't exist, that's pretty self explanatory too
<0> hm.. how can i make my code, cut the output after the first . in a number?=
<20> matthewcrane: break the problem down into bits, first tackle the image uploading, php.net/file-upload
<19> but I've just told you that the file is deleted just with unlink
<0> i have like 45.0094324 and 54.99023 and i want to just have the first 2 numbers. like 45 and 54
<19> but why the error ?
<20> roniez: explode
<20> ace_me: the file isn't there when unlink is run!
<20> ace_me: maybe you're running unlink more than once?
<19> whoe delete ithat than ?
<19> aha
<19> maybe
<19> ok
<19> I'll look again
<19> thx
<18> cheers aidan
<21> how do i output a 'unsigned short' in php as binary? i.e. 1380 would be 0x05 0x64 (two bytes)
<20> please don't spam the channel with 6 lines when "okay" was appropriate, ace_me
<20> dongs: php.net/sprintf
<19> k again
<21> how does that help me.
<21> i dont want it formatted, i want it output as bytes.
<22> ace_me: let me guess.. you have a dir.. upload and a file documentation.php
<20> you want the actual bytes output to the page? or you want 0x05 as text?
<21> i want the actual bytes.
<21> because its not going to a 'page'.
<20> dongs: pack/unpack
<21> k
<21> that sounds more like it
