分析PHP脚本执行时间的最简单方法
|
不需要扩展,只需使用这两个函数进行简单的分析。 // Call this at each point of interest,passing a descriptive string function prof_flag($str) { global $prof_timing,$prof_names; $prof_timing[] = microtime(true); $prof_names[] = $str; } // Call this when you're done and want to see the results function prof_print() { global $prof_timing,$prof_names; $size = count($prof_timing); for($i=0;$i<$size - 1; $i++) { echo "{$prof_names[$i]} echo sprintf(" %f } echo "{$prof_names[$size-1]} } 下面是一个示例,调用prof_flag(),每个检查点都有一个描述,最后是prof_print(): prof_flag("Start"); include '../lib/database.php'; include '../lib/helper_func.php'; prof_flag("Connect to DB"); connect_to_db(); prof_flag("Perform query"); // Get all the data $select_query = "SELECT * FROM data_table"; $result = mysql_query($select_query); prof_flag("Retrieve data"); $rows = array(); $found_data=false; while($r = mysql_fetch_assoc($result)) { $found_data=true; $rows[] = $r; } prof_flag("Close DB"); mysql_close(); //close database connection prof_flag("Done"); prof_print(); 输出看起来像这样: 开始 0.004303 连接到DB 0.003518 执行查询 0.000308 检索数据 0.000009 关闭DB 0.000049 完成 (编辑:安卓应用网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
