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 "";

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 "";

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 "";

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'].'
';

}

}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 ""-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/transitional.dtd\">

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;

}

width."px\">

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

width."px\">

";

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

}
