So I've read the two related questions for calculating a trend line for a graph, but I'm still lost.
I have an array of xy coordinates, and I want to come up with another array of xy coordinates (can be fewer coordinates) that represent a logarithmic trend line using PHP.
I'm passing these arrays to javascript to plot graphs on the client side.
PHP, Cold Fusion, and ASP (among many others) are usually sold on their strengths. What are their weaknesses? If one were to develop a niche product to handle the things that these products weren't so good at, what should it focus on?
I'm using the Markdown library for PHP by Michel Fortin. I started noticing that it formats the text in tags with markdown rules, like so:
http://foo.com/My_Url_With_Underscores
essentially becomes:
<a href="...">http://foo.com/My<em>Url</em>With_Underscores</a>
How do I disable that behavior or otherwise prevent the library from doing that?
One from here:
$sth->execute(array(':calories' => $calories, ':colour' => $colour));
The other from here:
/*** reassign the variables again ***/
$data = array('animal_id'=>4, 'animal_name' => 'bruce');
/*** execute the prepared statement ***/
$stmt->execute($data);
My question is: :key or key ?
Sorry I don't have the PHP environment here.
Hi All,
I know how to loop through items of an array using foreach and append a comma, but it's always a pain having to take off the final comma. Is there an easy PHP way of doing it?
$fruit = array('apple', 'banana', 'pear', 'grape');
Ultimately I want
$result = "apple, banana, pear, grape"
In PHP I'm running a mysql_query that has an ORDER BY clause. I'm then iterating through the results to build an associative array, with the row_id as the key.
Then, I'm calling json_encode on that array and outputting the result.
This page is loaded with AJAX, and defined in a Javascript variable. When I iterate through that Javascript variable, will I still have the order that was returned from the mysql_query?
I want a simple form with one text box and a submit button. If a user enters "foobar" into the text box and hits enter, they should be redirected to mysite.com/browse/foobar
Does anyone know how I can do this in php? thanks
It seems like I can't use shell_exec or proc_open on my shared server.
The message I get when I try to use it is:
Warning: shell_exec() has been disabled for security reasons in /home/georgee/public_html/admin/email.php on line 4
Are there any alternatives to these functions?
I have an array called $times. It is a list of small numbers (15,14,11,9,3,2). These will be user submitted and are supposed to be minutes. As PHP time works on seconds, I would like to multiply each element of my array by 60.
I've been playing around with array_walk and array_map but I can't get those working :S
Thanks.
I consider myself quite fluent in PHP and am rather familiar with nearly all of the important aspects and uses, as well as its pratfalls. This in mind, I think the major problem in taking on Perl is going to be with the syntax. Aside from this (a minor hindrance, really, as I'm rather sold on the fact that Perl's is far more readable), what are some key differences you think I should make myself aware of prior to taking on the language?
The idea is to have a PHP script parse a given .patch file and will apply the given patch accordingly. Assume that the script has no access to command line so the script will have to do the parsing itself. Is there a library somewhere?
Hi everyone,
I have recently heard a lot of people argue about using PHP testing features like PHPunit and SimpleTest together with their IDE of choice (Eclipse for me). After googling the subject, I have still a hard time understanding the pros and cons of using these testing frameworks to speed up development.
If anyone could explain this for me in a more basic level, I would really appreciate it. I am using PHP5 for the notice.
Thanks a lot!
I doubt if this is encryption but I can't find a better phrase. I need to pass a long query string like this:
http://test.com/test.php?key=[some_very_loooooooooooooooooooooooong_query_string]
The query string contains NO sensitive information so I'm not really concerned about security in this case. It's just...well, too long and ugly. Is there a library function that can let me encode/encrypt/compress the query string into something similar to the result of a md5() (similar as in, always a 32 character string), but decode/decrypt/decompress-able?
Hey guys recently I have had the 'priveledge' of trying to set up an anti virus scanner to scan file uploads to my VPN server. I just finished trying to set up ClamAV but it slowed my server down to a hault once initiated so I had to kill it. Does anyone have any recommendations to a program that will accomplish my task and can be executed in php (other than clamAv)? Any advice greatly appreciated.
Hello,
Is there a list of pros-cons for deploying a PHP application on the cloud for AWS or Azure?
Which factors would make AWS a better choice over Azure and Vice-versa?
If anyone has chosen to use, either one instead of the other for a number or reasons i would really want to know why.
regards,

Hi,
I am trying to develop a PHP class which would enable me to get the query string appended into a url and process it according to the variables passed. How can this be done?
Eg
www.example.com?var1=a&var2=b&var3=c
now I want to get '?var1=a&var2=b&var3=c' section and process it based on the variables.
Thanks
What can I do to make my PHP web application fail in a more noisy way?
I am using an MVC pattern and often when classes fail to load or failures they do so without error.
