数组函数 example

函数array()
描述:
建立一个数组
array array(...)传回一数组的值,这些值可以用=>来附值。
下面说明了如何构建一个二维数组,及如何指定这个数组的key,以及在正常的数组中以跳序的方式去指定数组的值。
Example 1. array()

$fruits = array(
"fruits" => array("a"=>"orange","b"=>"banana","c"=>"apple"),
"numbers" => array(1, 2, 3, 4, 5, 6),
"holes" => array("first", 5 => "second", "third")
);

函数array_walk()
描述:
函数的方式对每个数组的元素做处理
int array_walk (array arr, string func);
使用一个叫FUNC的函数对ARR的每个元素做处理,那些元素将当成是首传给FUNC的参数;假如FUNC需要超过一个参数,则在每次array_walk()呼叫FUNC时都产生一个警告信息,这些警告信息是可以消除的,只要把'@'符号加在array_walk()
之前即可。
注重:FUNC会直接对ARR中的元素做处理,所以任何元素的变化将直接改变其在数组中的值。
Example 1. array_walk() example

$fruits = array("d"=>"lemon","a"=>"orange","b"=>"banana","c"=>"apple");
function test_alter( $item1 ) { $item1 = 'bogus'; }
function test_print( $item2 ) { echo "$item2
"; }
array_walk( $fruits, 'test_print' );
array_walk( $fruits, 'test_alter' );
array_walk( $fruits, 'test_print' );

函数arsort()
描述:
以倒序的方式排列一数组但其序数则不变

void arsort (array array);

This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant. Example 1. arsort()

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
