这样的循环 我要截取第一条,多的不要
标题标题回复讨论(解决方案)
preg_match_all("|<li><a href=[\"\']\/(.*)\/(.*)[\"\']><img (.*) alt="正则截取html中的一段" >(.*)</a></li>|U", $str, $out);$a = $out[2][0];$b = $out[4][0];echo "a::$a , b::$b"; 页面有点大,有没有更高效的方法!!!!!!!
preg_match('#<ul class="style5">(.+?)</ul>#s',$s,$m);preg_match('#<li><a href="/profiles/(\d+)"><img [^ alt="正则截取html中的一段" >]+>(.+?)</a></li>#s',$m[1],$ar);print_r($ar);

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency 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.

PHP Performance: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AMPHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
