<?php$guanggaotutiao1=$_MODULE["guanggaotiao1"];if($guanggaotutiao1){ $bjjs='background:url('.$guanggaotutiao1.')'; }else{ $bjjs=''; }?>
输入函数参数guanggaotiao1 出现上面的效果 的函数
$guanggaotutiao1是全局哦
这个函数怎么写??
回复讨论(解决方案)
$guanggaotutiao1=$_MODULE["guanggaotiao1"];function guangGao($url){ if($guanggaotutiao1){ $bjjs='background:url('.$guanggaotutiao1.')'; }else{ $bjjs=''; } return $bjjs;}guanGao($guanggaotutiao1);
$guanggaotutiao1=$_MODULE["guanggaotiao1"];function guangGao($url){ if($guanggaotutiao1){ $bjjs='background:url('.$guanggaotutiao1.')'; }else{ $bjjs=''; } return $bjjs;}guanGao($guanggaotutiao1);不对啊 $guanggaotutiao1这个会变得
$guanggaotutiao1=$_MODULE["guanggaotiao1"];function guangGao($url){ if($guanggaotutiao1){ $bjjs='background:url('.$guanggaotutiao1.')'; }else{ $bjjs=''; } return $bjjs;}guanGao($guanggaotutiao1);不对啊 $guanggaotutiao1这个会变得
$guanggaotutiao1=$_MODULE["guanggaotiao1"];这个不就是获取变化的$guanggaotutiao1吗?
然后再调用 guangGao();这个函数呀!
<?phpfunction guangao(){ global $guanggaotutiao1; if($guanggaotutiao1) { $bjjs='background:url('.$guanggaotutiao1.')'; } else { $bjjs=''; } return $bjjs;}?>
无需函数
$bjjs = $_MODULE["guanggaotiao1"] ? 'background:url('.$_MODULE["guanggaotiao1"].')' : '';
一定要写成函数的话
function background($url) {
return $url ? "background:url($url)" : '';
}
调用
$bjjs = background($_MODULE["guanggaotiao1"]);

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
