示例 #1 Xhprof 范例，可選使用圖形界面
本示例啟動并結(jié)束性能分析器，然后使用捆綁的用戶界面來保存和解析結(jié)果。 換言之，擴(kuò)展的代碼在調(diào)用 xhprof_disable() 函數(shù)后結(jié)束。
<?php
xhprof_enable(XHPROF_FLAGS_CPU + XHPROF_FLAGS_MEMORY);
for ($i = 0; $i <= 1000; $i++) {
$a = $i * $i;
}
$xhprof_data = xhprof_disable();
$XHPROF_ROOT = "/tools/xhprof/";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_lib.php";
include_once $XHPROF_ROOT . "/xhprof_lib/utils/xhprof_runs.php";
$xhprof_runs = new XHProfRuns_Default();
$run_id = $xhprof_runs->save_run($xhprof_data, "xhprof_testing");
echo "http://localhost/xhprof/xhprof_html/index.php?run={$run_id}&source=xhprof_testing\n";
?>
以上例程的輸出類似于：
http://localhost/xhprof/xhprof_html/index.php?run=t11_4bdf44d21121f&source=xhprof_testing
