Random ad display calling code in php_PHP tutorial
This article will introduce you to the method of using txt and php to realize random advertising display and calling. The principle is very simple. We put the advertising file into the txt file. When a user visits, we load the txt file and then come out randomly.
代码如下 | 复制代码 |
#########随机广告显示########## function myads(){ $dir="ads"; #设置存放记录的目录 //$dir="ads"; #设置存放记录的目录 $ads="$dir/ads.txt"; #设置广告代码文件 $log ="$dir/ads.log"; #设置ip记录文件 $ads_lines=file($ads); $lines=count($ads_lines);#文件总行数 ####读出广告总数$ads_count和显示次数到数组$display_array######## $ads_count=0; $display_count=0; for ($i=0;$i if((!strcmp(substr($ads_lines[$i],0,7),"display"))){ $ads_count+=1; $display_array[$ads_count]=substr($ads_lines[$i],8); $display_count+=$display_array[$ads_count]; } } ####决定随机显示序号$display_rand##### srand((double)microtime()*1000000); $display_rand = rand(1,$display_count); ###决定广告序号$ads_num###### $pricount=0; $ads_num=1; for($i=1; $i $pricount += $display_array[$i]; if ($display_rand } #####播放广告######## $num=0; $flag=0; for($i=0;$i if((!strcmp(substr($ads_lines[$i],0,7),"display"))){$num++;} if(($num==$ads_num)and($flag==0)){$flag=1;continue;} if(($flag==1)and strcmp($ads_lines[$i][0],"#")){echo $ads_lines[$i];continue;} if(($flag==1)and(!(strcmp($ads_lines[$i][0],"#")))){break;} } ####纪录广告显示次数######### $fp=fopen($log,"a"); fputs($fp,date( "Y-m-d H:i:s " ).getenv("REMOTE_ADDR")."==>".$ads_num."n"); fclose($fp); } ?> |

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
