performance - Fastest way to generate and check numbers in PHP? -


I need some help in creating numbers in PHP, for example by checking that if the number is below 100 Then give 0.1 points. It is for a coin system that is called when some actions are used in flash games.

I want to do it in the fastest time and this is the code that I am using before testing it. I update it on the main server for the game. 

  & lt ;? Php $ coins = 0; $ Rand = rand (0, 1000); If ($ rand <50) {$ Coins = $ Coins + 0.01; } If ($ RAND & LT; 100 & amp; RAND & gt; 50) {$ Coins = $ Coins + 0.2; } If ($ rand> 100 & amp; amp; amp; $ Rand <200) {$ coins = $ coins + 0.2; } If ($ rand> 500) {$ Coins = $ Coins + 0.5; } Echo "coins generated coins \ n"; ? & Gt;   
 Sorry, if someone does not understand my search in some words, then I am asking how fast I can do it and someone has a suggestion for it. ? Instead of using  rand () , consider using the 
 
 
 
 
 . From Docs:  
 
 Many random number generators of old labels have suspicious or unknown features and are slow. By default, the PHP rand () function uses libc random number generator with the function. The Mt_rand () function is a drop-in replacement for this. It uses a random number generator, which will be four times faster than the »One» Marson Twister, which provides the random number  Average libc rand ().  Apart from this, there is another similar thread to discuss another topic here:  
 I'm not sure what kind of optimization you have here Looking forward and would like to repeat the comments of Frank Farmer from that discussion:  
 
 Why are you so concerned about the speed with this special operation? Have you done a profile? How long can you survive by choosing one on another? ... Allow me to direct more: This does not make a significant difference. We are talking about a difference measured in nanosecond

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
