复制代码 代码如下:


// 定义全局变量 记录时间
$_timer_id = 0;
// 函数设置全局变量 记录各个断点的运行所需时间
function makeTimer( $notes, $onOff=FALSE )
{
if( $onOff )
{
global $_timer_id;
$GLOBALS['timer'][$_timer_id][0] = microtime(TRUE);
$GLOBALS['timer'][$_timer_id][1] = $notes;
$_timer_id++;
}
}
// 把全局运行时间情况输出
function traceTimer()
{
$timer_str = '';
$G_timer = count($GLOBALS['timer'])-1;
if( $G_timer>0 )
{
for( $i=0;$i{
$dif_time = number_format( ($GLOBALS['timer'][$i+1][0] - $GLOBALS['timer'][$i][0]), 3 );
$timer_str .= 'dif: '.$dif_time.' '.$GLOBALS['timer'][$i][1]."\n";
}
$dif_time = number_format( (microtime(TRUE) - $GLOBALS['timer'][$G_timer][0]), 3 );
$timer_str .= 'dif: '.$dif_time.' '.$GLOBALS['timer'][$G_timer][1]."\n";
}
return $timer_str;
}
使用方法:
// 开始时间
makeTimer( ' LINE:'.__LINE__ );
$imgstrpos = strpos($str, '全局记录程序片段的运行时间 正确找到程序逻辑耗时多的断点makeTimer( ' LINE:'.__LINE__ );
$str_p = substr($str_noimg, 0, $imgstrpos);
makeTimer( ' LINE:'.__LINE__ );
$str_n = substr($str_noimg, $imgstrpos, strlen($str_noimg));
makeTimer( ' LINE:'.__LINE__ );
$pst_exc_imgs = $str_p.'全局记录程序片段的运行时间 正确找到程序逻辑耗时多的断点'.$str_n." ";
makeTimer( ' LINE:'.__LINE__ );
// 记录到日志中
error_log( traceTimer(), 3, '/tmp/'.basename(__FILE__).'.log' );
// 或者直接输出
echo traceTimer();
