In PHP I would like to introduce two more commonly used array filter function Array_filter and Array_unique, one is to filter the array null, one is to filter the array of duplicate values, we now look together. GrammarArray_filter

PHP generated graphics verification code needs to use the PHP GD library and the session to the instance, so the GD library generated images to the user to see, and then by the user input validation submitted to the server and the session stored

This article introduces the use of session storage and GD library to generate a verification code program, at the same time will add some interference elements, so that you can simple anti-machine registration, I would like to introduce you to the

First, the contents of the experiment1, the experimental requirements: there is a four-bit positive integer, the composition of the four-digit four numbers are different, if their first and last interchange, the second and the third interchange, the

MongoDB itself has two integer types: 32-bit integers and 64-bit integers, but older PHP drivers, regardless of whether the operating system is 32-bit or 64-bit, treat all integers as 32-bit integers, resulting in a 64-bit integer being truncated.

Write a verification code class in PHP and encapsulate it. class Name: validationcode.class.phpThe code is as follows: Copy CodeThe code is as follows: Class Validationcode { Private $width; Private $height; Private $codeNum; Private $image;

Integer Problems and Countermeasures when operating MongoDB in PHP. The PHP-138target_blank integer problem mentioned in this article is not the MongoDB problem, but the PHP driver problem: MongoDB itself has two integer types, respectively: the

With the development of the times, our programming technology is also more and more, for PHP presumably everyone knows it, we introduce the PHP array here. PHP arrays are the most common bulk data storage structures, and because arrays are stored

In the case of small $inttotal, for example, within 1000, the value of $intRand basically does not affect the results, the two execution time is similar. When the test $inttotal is greater than 10000, the efficiency of using array_unique is higher
