这篇文章主要介绍了关于php导入进度条类，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下
最近在做一个客户导入的功能，整理的一个导入的进度条类：
<?php/** * @file name: loading.php * @author: jiumi.jin * @create time: 10/11/2012 * @main function: loading */class loading { private $width = 500; private $total = 0; private $start_time; private $failelines = array(); private $failecounter = 0; /** * 构造 * @param 进度条长度 $width * @param 要处理的数据长度 $length */ public function __construct($param){ ob_start(); //$this->width = $width; $this->total = $param['length']; $this->start_time = time(); ob_end_clean(); } /** * 执行进度跟踪 * @param $num 执行的数据点，这个数字应该是0 到 数据的总长度 * @return bool */ public function run($num){ $successnum = $num - $this->failecounter; $percent = number_format($num / $this->total * 100,2) . '%'; echo "<script>updatepercent('$successnum',$this->failecounter,'$percent');</script>"; print str_pad("",100000); ob_flush(); return true; } /** * 占用内存跟踪 * @param $i 进度 * @param $progress_mem 占用内存 * @return bool */ public function run_mem($i,$progress_mem){ echo "<script>showmem($i,$progress_mem);</script>"; print str_pad("",100000); ob_flush(); return true; } /** * 设置出错的点 * 例如导入excel的时候，有不符合模板规范的行数可以在这里设置 * @param $line 错误行数 * @param $errmes 错误信息 */ public function setfaileline($line,$errmes){ $line = intval($line); if ($line != 0) { $this->failecounter++; $this->faile = true; $this->failelines[$this->failecounter]['line'] = $line; $this->failelines[$this->failecounter]['errmessage'] = $errmes; echo "<script>showerr('".$this->getfaileline()."');</script>"; print str_pad("",100000); ob_flush(); return true; } } public function getfailecounter(){ return $this->failecounter; } /** * 获取出错的点 * * @return string $html */ public function getfaileline(){ $html = ''; if(!empty($this->failelines)){ foreach($this->failelines as $failline){ $html .= '错误位置：'.$failline['line'].'， 错误信息：'.$failline['errmessage'].'<br/>'; } }else{ $html .= '没有错误信息'; } return $html; } /** * echo出进度条的html页面和js函数 * 应该在实例化类后立刻执行此方法，否则会失败 * * @return unknown */ public function createhtml(){ echo "<!doctype html public \"-//w3c//dtd xhtml 1.0 transitional//en\" \"http://www.w3.org/tr/xhtml1/dtd/transitional.dtd\"> <html> <head> <script> function updatepercent(have_process,errcount,percent){ document.getelementbyid('msg').innerhtml = '成功处理了 '+have_process+' 条数据'; document.getelementbyid('errmsg').innerhtml = '失败 '+errcount+' 条数据'; document.getelementbyid('progress').style.width = percent; document.getelementbyid('percent').innerhtml = percent; if(document.getelementbyid('progress').style.width == '100%'){ document.getelementbyid('percent').innerhtml = '处理完毕！'; stop(); } } function showerr(msg){ document.getelementbyid('allerr').innerhtml = msg; } //计时 var calltimelen = \"0\"; var timer1 = null; function start(){ var hour=\"0\"; var minute=\"0\"; var second=\"0\"; calltimelen = parseint(calltimelen)+1; hour = parseint(calltimelen/3600); minute = parseint(calltimelen/60); second = calltimelen%60; document.getelementbyid('time_h').innerhtml = hour; document.getelementbyid('time_m').innerhtml = minute; document.getelementbyid('time_s').innerhtml = second; window.timer1 = window.settimeout(\"start()\",1000); } settimeout(\"start()\",0); function stop(){ cleartimeout(window.timer1); } function showmem(i,progress){ document.getelementbyid('showm').innerhtml = '_____'+i+': '+progress; } </script> </head> <body> <p style=\"margin:0 auto; margin-top:4px; margin-bottom:0; padding: 8px; padding-bottom:0; border: 1px solid gray; background: #eaeaea; width:".$this->width."px\"> <p><font color=\"gray\"><span style=\"font-size:12px;\">此操作需要等待一段时间，在执行完毕之前，请不要关闭此页面</span></font></p> <p style=\"padding: 0; background-color: white; border: 1px solid navy; width:".$this->width."px\"> <p id=\"progress\" style=\"padding: 0; background-color: #ffcc66; border: 0; width: 0px; text-align: center; height: 16px\"></p> </p> <p id=\"msg\" style=\"font-size:12px;\"></p> <p id=\"errmsg\" style=\"font-size:12px;\"></p> 已用时：<span id=\"time_h\"> </span>时 <span id=\"time_m\"> </span>分 <span id=\"time_s\"> </span>秒 <p id=\"showm\" style=\"font-size:12px;\"></p> <p id=\"percent\" style=\"position: relative; top: -32px; text-align: center; font-weight: bold; font-size: 8pt;\">0%</p> </p> <p id=\"allerr\"> </p> <body> </html>"; return true; }}
ci框架的调用：
$this->load->library('loading',array('length'=>$totle)); //加载进度条类,这是ci框架$this->loading->createhtml();//$start_mem = memory_get_usage();foreach($customers as $key=>$customer){ $return = $this->insert_import($customer); if($return != 1){ $this->loading->setfaileline($key+1,$return); //记录错误 }else{ $this->loading->run($key+1); //成功进度条 } //$progress_mem = memory_get_usage(); //$this->loading->run_mem($key,$progress_mem-$start_mem); //测试查看内存使用情况的}
