php获取url里指定位置的参数
php获取url里指定位置的参数,因为url后的参数是变动的。怎样获取呢?如www.xxx.com?act=game&st=play&b1=1&round=1,有时候这个url会输出成www.xxx.com?act=game&st=play&b2=2&round=1,其中的b1、b2、b3.。。。一直到b15.怎样获取这个url输出的b1还是b2还是其他及他的值呢
------解决思路----------------------
把查询字符串输出成一个数组不就行了
------解决思路----------------------
用名字访问
$s = 'www.xxx.com?act=game&st=play&b1=1&round=1';<br /><br />parse_str(@array_pop(explode('?', $s)), $a);<br />print_r($a);<br /><br />$s = 'www.xxx.com?act=game&st=play&b2=2&round=1';<br /><br />parse_str(@array_pop(explode('?', $s)), $a);<br />print_r($a);Array
(
[act] => game
[st] => play
[b1] => 1
[round] => 1
)
Array
(
[act] => game
[st] => play
[b2] => 2
[round] => 1
)

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
