php数组中包含中文的排序方法
php数组中文排序,文件格式一般用utf8,直接用asort排序不行。若是gbk和gb2312可以。这跟编码有关。gbk和gb2312本身的编码就是用拼音排序的。
复制代码 代码如下:
function utf8_array_asort(&$array) {
if(!isset($array) || !is_array($array)) {
return false;
}
foreach($array as $k=>$v) {
$array[$k] = iconv('UTF-8', 'GB2312',$v);
}
asort($array);
foreach($array as $k=>$v) {
$array[$k] = iconv('GB2312', 'UTF-8', $v);
}
return true;
}
使用例子:
复制代码 代码如下:
$abc = array('a'=>'猜', 'b'=>'我','c'=>'哦','d'=>'棍','e'=>'f','f'=>'爸','z'=>'州');
utf8_array_asort($abc);
print_r($abc);
但是使用这个函数发现,有些文字会出错,可能是utf8编码认不出某些字导致的“非法字符”,据了解GBK字符集比较大,换成GBK,再加上IGNORE忽略掉不认识的字符 ,改成下面这样
复制代码 代码如下:
private function utf8_array_asort(&$array) {
if(!isset($array) || !is_array($array)) {
return false;
}
foreach($array as $k=>$v) {
$array[$k] = iconv('UTF-8', 'GBK//IGNORE',$v);
}
asort($array);
foreach($array as $k=>$v) {
$array[$k] = iconv('GBK', 'UTF-8//IGNORE', $v);
}
return true;
}

How to use PHP arrays to generate and display charts and statistical graphs. PHP is a widely used server-side scripting language with powerful data processing and graphic generation capabilities. In web development, we often need to display charts and statistical graphs of data. Through PHP arrays, we can easily implement these functions. This article will introduce how to use PHP arrays to generate and display charts and statistical graphs, and provide relevant code examples. Introducing the necessary library files and style sheets Before starting, we need to introduce some necessary library files into the PHP file

How to use PHP arrays to generate dynamic slideshows and picture displays. Slideshows and picture displays are common functions in web design and are often used in scenarios such as carousels and gallery displays. As a popular server-side scripting language, PHP has the ability to process data and generate dynamic HTML pages, and is very suitable for generating dynamic slideshows and picture displays. This article will introduce how to use PHP arrays to generate dynamic slideshows and picture displays, and give corresponding code examples. Prepare image data First, we need to prepare a set of image path data

How to use PHP arrays to implement user login and permission management functions When developing a website, user login and permission management are one of the very important functions. User login allows us to authenticate users and protect the security of the website. Permission management can control users' operating permissions on the website to ensure that users can only access the functions for which they are authorized. In this article, we will introduce how to use PHP arrays to implement user login and permission management functions. We'll use a simple example to demonstrate this process. First we need to create

There are several ways to determine an array in PHP: 1. Use the count() function, which is suitable for all types of arrays. However, it should be noted that if the parameter passed in is not an array, the count() function will return 0; 2. Use the sizeof() function, which is more used to maintain compatibility with other programming languages; 3. Custom functions, By using a loop to traverse the array, each time it is traversed, the counter is incremented by 1, and finally the length of the array is obtained. Custom functions can be modified and expanded according to actual needs, making them more flexible.

PHP array key-value pair is a data structure consisting of a key and a corresponding value. The key is the identifier of the array element, and the value is the data associated with the key. It allows us to store and access data using keys as identifiers. By using key-value pairs, we can more easily operate and manage elements in the array, making program development more flexible and efficient.

PHP array is a very common data structure that is often used during the development process. However, as the amount of data increases, array performance can become an issue. This article will explore some performance optimization techniques for PHP arrays and provide specific code examples. 1. Use appropriate data structures In PHP, in addition to ordinary arrays, there are some other data structures, such as SplFixedArray, SplDoublyLinkedList, etc., which may perform better than ordinary arrays in certain situations.

An effective way to implement array union in PHP: use the array_merge() function to merge multiple arrays, but not merge duplicate values. Combine array_unique() and array_merge() to merge arrays and keep duplicate values. Create a custom function to merge arrays based on specific requirements, such as merging sorted arrays.

The functions that PHP uses to determine if an array is empty are the "empty()" function and the "count()" function. 1. The "empty()" function is used to determine whether a variable is empty, including determining whether an array is empty. Its syntax is "empty($variable)"; 2. The "count()" function is used to count arrays. The number of elements, the syntax is "count($array)".
