  • What PHP function(s) can I use to perform operations on non-integer timestamps?

    - by stephenhay
    Disclaimer, I'm not a PHP programmer, so you might find this question trivial. That's why I'm asking you! I've got this kind of timestamp: 2010-05-10T22:00:00 (That's Y-m-d) I would like to subtract, say, 10 days (or months, whatever) from this, and have my result be in the same format, i.e. 2010-04-30T22:00:00. What function(s) do I need to do this in PHP? Note: I'm using this to do a computed field in Drupal. The result will be the date that an e-mail is sent. Bonus question: If 2010-05-10T22:00:00 means "May 10, 2010 at 10pm", is there a timestamp equivalent of "May 10, 2010 (all day)"? Thanks everyone.

    - by John
    When I run some php code I've written, I get the following message: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'condition, price, name, email) VALUES('Fake Title', 'Fake Subhead', 'Fake Author' at line 1 I do not see anything wrong with my syntax, however, which is like: mysql_query("INSERT INTO table (x1, x2, x3) VALUES('$y1', '$y2', '$y3')"); Any ideas?

  • JavaScript: document properties

    - by deb
    Hi, is there a "document" property named ssh? It's a simple question. I've seen this in some code at work, but no one in the office wrote the code, so I'm stucked. The line was document.ssh.firstPing(...) firstPing was a method in the code, that is writen in js+php. But I've searched with eclipse throughout all the code and there is no ssh anywhere.

  • Uninterrupted mp3 play on a website?

    - by Kevin
    Client is requesting a single track to be heard across the website. Generally I advise against it, but they insist. So, what is the most straightforward way of having a flash player embedded in a site, and when a user goes to another page there isn't a gap/interruption? I am thinking an iframe is required.. I am using a flash player that has autoresume, but that only solves picking up where you last left off on the song before going to another page. I tried searching SO for an answer..

  • A php namespace called default

    - by michael
    <?php namespace default gives me an unexpecected T_DEFAULT, is there any way of working around this? Can I escape the reserved word somehow? My system uses the name of the current module in my site for the namespace so it would be nice to be able to use any string as a namespace.

  • adding remote files to a zip file

    - by Borgtex
    Is there a way to add files to a zip file from another server with php's zip extension? ie. addFile(array('localfile.txt,'http://www.domain.com/remotefile.txt')) (that obviously does not work) I suppose I can download the files to a temporal folder and then add them to the zip file, but I was looking for a more automated solution or a function already made

  • Why are interfaces unusable in PHP?

    - by streetparade
    I mean an interface definition without defining the return type makes it unusable? This makes more Clear Interface run { public function getInteger(); } class MyString implements run { public function myNumber() { } public function getInteger() { return "Not a number"; } } In Java every Interface has a return type like Integer,String,Void I know that PHP is unfortunately a loosly typed Language but isnt there a Solution for that Problem? Is it Possible to defining a Interface with a Return type like Integer?

  • A good php framework in 2012

    - by Jormundir
    I've done a lot of googling around this, and practically all of the answers I find are pre 2011, and are answered in the usual, here are the 5 most popular frameworks... So I'd like to update this topic for 2012, I'm going to build a web application with a pretty complex back-end system driving it, and I'd like to use a framework so I don't have to reinvent the wheel. My application will be hugely user based, so I would appreciate a built in authentication/validation system. (When this is missing it takes me a good 2 weeks of intense and frivolous research to try to pick the "best" one (I don't want to roll my own, I don't think I'd do a better job than what's out there). I've looked into a tried a few, so I'll give you what I like and don't like, but I don't want to bias answers too much. I don't like: Frameworks that auto-generate bloated code. If they have the feature, fine, but if I have to use it, I get frustrated. Backwards compatibility with php4, eww. I don't need backwards compatibility at all. I like: Getting up and running quickly (but without all the auto-generation bogus), what I mean by this is that all the essentials are there, so I don't have to come to a grinding halt to research what the best 3rd party plugin is to get the feature I need. Thorough documentation, good tutorials. Good presentation of these materials. Please explain why your framework suggestion is good, don't just give the name of a framework without any justification. Thanks!

  • How do I improve this linear regression function?

    - by user558383
    I have the following PHP function that I'm using to draw a trend line. However, it sometimes plots the line below all the points in the scatter graph. Is there an error in my function or is there a better way to do it. I think it might be something to do with that with the line it produces, it treats all the residuals (the distances from the scatter points to the line) as positive regardless of them being above or below the line. function linear_regression($x, $y) { $n = count($x); $x_sum = array_sum($x); $y_sum = array_sum($y); $xx_sum = 0; $xy_sum = 0; for($i = 0; $i < $n; $i++) { $xy_sum+=($x[$i]*$y[$i]); $xx_sum+=($x[$i]*$x[$i]); } $m = (($n * $xy_sum) - ($x_sum * $y_sum)) / (($n * $xx_sum) - ($x_sum * $x_sum)); $b = ($y_sum - ($m * $x_sum)) / $n; return array("m"=>$m, "b"=>$b); }

  • How does this code block works?

    - by Justin John
    I can't understand how the following code works. $start = 1; while($start<10){ if ($start&1) { echo "ODD ".$start." <br/> "; } else { echo "EVEN ".$start." <br/> "; } $start++; } The $start&1 will return ODD and EVEN seperately. Output ODD 1 EVEN 2 ODD 3 EVEN 4 ODD 5 EVEN 6 ODD 7 EVEN 8 ODD 9 If we give $start&2 instead of $start&1, it returns with another order. How &1 &2 etc... works here?
