Numeric Captcha for PHP

[亡魂溺海] 提交于 2019-11-29 02:33:35
Is there a numeric captcha available for PHP ? ( which doesn't rely on JavaScript being turned on ) EDIT: I know there are JS-independent captchas out there. I know there are PHP captchas out there. I know there are numeric captchas out there. But I'm looking for a PHP numeric Javascript-independent captcha. The only numeric captcha's I've found are either for ASP.NET or jQuery/JS based ones. I don't want any of those as an answer to the question. And I'm not taking about a small website here. In the answer I'd like to know whether your suggestion puts a lot of strain on the server or not. I

Formatting Large Numbers with .NET

你离开我真会死。 提交于 2019-11-29 02:12:18
I have a requirement to format large numbers like 4,316,000 as "4.3m". How can I do this in C#? You can use Log10 to determine the correct break. Something like this could work: double number = 4316000; int mag = (int)(Math.Floor(Math.Log10(number))/3); // Truncates to 6, divides to 2 double divisor = Math.Pow(10, mag*3); double shortNumber = number / divisor; string suffix; switch(mag) { case 0: suffix = string.Empty; break; case 1: suffix = "k"; break; case 2: suffix = "m"; break; case 3: suffix = "b"; break; } string result = shortNumber.ToString("N1") + suffix; // 4.3m divide the number by

How to apply css to only numbers in a text inside/or any <p><p> element?

I am Using a Regional language unicode font-face in my site but the numbers are not looking good. So I want to apply new font-style or css to numbers only.. please help This can be done using CSS's unicode-range property which exists within @font-face . The numbers 0 to 9 exist in Unicode within the range U+0030 to U+0039 . So what you'll need to do is include a font alongside your existing font which specifically targets this range: @font-face { font-family: 'My Pre-Existing Font'; ... } @font-face { font-family: 'My New Font Which Handles Numbers Correctly'; ... unicode-range: U+30-39; } The

Set a font specifically for all numbers on the page

感情迁移 提交于 2019-11-29 02:02:42
For my webpage, I chose a font that works well for all the letters. However, for all numbers I'd like to use a different font. Is there a way that I can set a CSS rule to target all the numbers on the page? If I can't do it strictly with CSS, my first thought is to use regular expressions to surround all numbers with a span with a "numbers" class and apply a font for that class. Is there a better way to do this? You can do it in JavaScript relatively simply by traversing the document so that you wrap any sequence of digits in a span element with a class attribute and declare font-family for it

Print all unique integer partitions given an integer as input

北慕城南 提交于 2019-11-29 01:58:01
问题 I was solving a programming exercise and came across a problem over which I am not able to satisfactorily find a solution. The problem goes as follows: Print all unique integer partitions given an integer as input. Integer partition is a way of writing n as a sum of positive integers. for ex: Input=4 then output should be Output= 1 1 1 1 1 1 2 2 2 1 3 4 How should I think about solving this problem? I was wondering about using recursion. Can anyone provide me an algorithm for this question?

MYSQL: Sequential Number Table

社会主义新天地 提交于 2019-11-29 00:29:47
I am trying to get a sequential number table from 1 to 20 million. (or 0 to 20 million) I am rather awestruck at how difficult it's been to get a MySQL-compatible solution to this common problem. Similar to this: Creating a "Numbers Table" in mysql But the the answer only goes to 1 million. I am not really understanding the bit shift calculations. I've seen many SQL answers but most are for databases that aren't MySQL, so I can't adopt the code due to lack of knowledge of both MySQL and the other. Some references: SQL, Auxiliary table of numbers What is the best way to create and populate a

how to tokenize string to array of int in c?

核能气质少年 提交于 2019-11-29 00:16:03
Anyone got anything about reading a sequential number from text file per line and parsing it to an array in C? What I have in a file: 12 3 45 6 7 8 3 5 6 7 7 0 -1 4 5 What I want in my program: array1[] = {12, 3, 45, 6, 7, 8}; array2[] = {3, 5, 6, 7}; array3[] = {7, 0, -1, 4, 5}; I've been through several ways to read it, but the only matter is only when i want to tokenize it per line. Thank you. The following code will read a file a line at a time char line[80] FILE* fp = fopen("data.txt","r"); while(fgets(line,1,fp) != null) { // do something } fclose(fp); You can then tokenise the input

Strange javascript operator: expr >>> 0 [duplicate]

问题 This question already has answers here : What is the JavaScript >>> operator and how do you use it? (7 answers) Closed 4 years ago . the following function is designed to implement the indexOf property in IE. If you've ever had to do this, I'm sure you've seen it before. if (!Array.prototype.indexOf){ Array.prototype.indexOf = function(elt, from){ var len = this.length >>> 0; var from = Number(arguments[1]) || 0; from = (from < 0) ? Math.ceil(from) : Math.floor(from); if (from < 0) from +=

Input type “number” won't resize

最后都变了- 提交于 2019-11-28 23:32:14
问题 Why won't my input resize when I change the type to type="number" but it works with type="text" ? EXAMPLE Email: <input type="text" name="email" size="10"><br/> number: <input type="number" name="email" size="10"> 回答1: Seem like the input type number does not support size attribute or it's not compatible along browsers, you can set it through CSS instead: input[type=number]{ width: 80px; } Updated Fiddle 回答2: Incorrect usage. Input type number it's made to have selectable value via arrows up

Using inherited overloaded methods

只愿长相守 提交于 2019-11-28 23:13:01
I have two classes: public class ClassA { public void method(Number n) { System.out.println("ClassA: " + n + " " + n.getClass()); } } and: public class ClassB extends ClassA { public void method(Integer d) { System.out.println("ClassB: " + d + " " + d.getClass()); } } But when I run: ClassA a = new ClassB(); a.method(3); I get: ClassA: 3 class java.lang.Integer My question is, why isn't ClassB 's method being used? a is an instance of ClassB , and ClassB 's method() has an Integer parameter...
