本文介绍了在PHP中提取文件并在图表中显示内容的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个名为test.txt的文件，其内容如下：
BEGIN_SESSION 7
1小时+ 47小时b $小时3000-1000小时20小时b小时1500-1000小时16小时b小时500-1,500小时43小时b小时2小时-500小时29小时b小时30-20小时35小时b小时0小时-30小时170
END_SESSION
感谢用户 wumm 它帮助我找到一种方法来提取数据并将其显示出来。所以问题是：我已经见证了在饼图中显示数据的这个函数： p>
函数awstats_extract_session（$ session）
{
＃会话范围 - 访问次数
$ session = explode（\\\
，$ session）;
unset（$ session [（count（$ session）-1）]）;
unset（$ session [0]）;
$ sessions = array（）;
foreach（$ session为$ key => $ value）{
$ session [$ key] = explode（，$ value）;
// print_array（$ session [$ key]）;
$ sessions [] = array（$ session [$ key] [0]，$ session [$ key] [1]）;
}
$ sessions = json_encode（$ sessions，JSON_NUMERIC_CHECK）;
？>
< div id =collapse_awstats_extract_sessionclass =accordion-body collapse in>
< div class =accordion-inner>
< div id =chart-sessionstyle =height：350px; width：700px; margin：0 auto;>< / div>
< / div>
< / div>
< script>
jQuery（document）.ready（function（）{
var data =<？php echo $ sessions;？> ;;
var plot1 = jQuery.jqplot（'chart-session' ，[data]，{
title：'Duréedes visites'，
seriesDefaults：{
renderer：jQuery.jqplot.PieRenderer，
rendererOptions：{
showDataLabels：真实的，
}，
}，
图例：{show：true，location：'e'}，
}）;
}）;
< / script>
还有一个函数可以调用前一个函数：
<？php
echo'< div class =accordion-group>';
$ b preg_match（/ BEGIN_SESSION（。*）END_SESSION / is，$ awstats，$ matches）;
$ session = $ matches [0];
preg_match（'/ 30s-2mn（[0-9] {2}）/ ms'，$ session，$ matches）;
$ a = $ matches [1];
preg_match（'/ 0s-30s（[0-9] {3}）/ ms'，$ session，$ matches）;
$ b = $ matches [1];
var_dump（$ a + $ b）;
awstats_title（< a class ='accordion-toggle'data-toggle ='collapse'data-parent ='＃accordion_awstats_navigation'href ='＃collapse_awstats_extract_session' < / span>< span class ='glyphicon glyphicon-collapse-down'>< / span>可持续发展< / a>，会话
awstats_extract_session（$ session）;
我希望显示所有内容，但最后两个30s-2mn 350s -30s 170
我想将其设置为0s-2mn 205。请帮助
PS：
或者有没有办法将文件test.txt更改为
BEGIN_SESSION 7
1h + 47
30mn-1h 20
1,500万-3,000万16
500-1,500万43
2mn-5mn 29
0s-2mn 205
END_SESSION
谢谢！
解决方案
$ b $
preg_match（/ BEGIN_SESSION（。*）END_SESSION / is，$ test，$ matches）;
$ session = $ matches [0];
preg_match（'/ 30s-2mn（[0-9] {2}）/ ms'，$ session，$ matches）;
$ a = $ matches [1];
preg_match（'/ 0s-30s（[0-9] {3}）/ ms'，$ session，$ matches）;
$ b = $ matches [1];
$ session = preg_replace（'/ 30s-2mn（[0-9] {2}）\\\
0s-30s（[0-9] {3}）/ ms'， 2mn（$ a + $ b），$ session）;
然后 $ session 包含您显示的文字在你的问题的最后一个代码示例中。
$ b
$ session 现在包含：
BEGIN_SESSION 7
1h + 47
30mn-1h 20
15mn -30mn 16
5mn -15mn 43
2mn-5mn 29
0s-2mn 205
END_SESSION
I have this a file named "test.txt" which has the following content:
BEGIN_SESSION 7
1h+ 47
30mn-1h 20
15mn-30mn 16
5mn-15mn 43
2mn-5mn 29
30s-2mn 35
0s-30s 170
END_SESSION
And thanks to the user wumm it help me to find a way to extract the data and display it.So the problem is :I've witten this function that display data in a pie chart :
function awstats_extract_session($session)
{
# Session range - Number of visits
$session = explode("\n", $session) ;
unset($session[(count($session)-1)]) ;
unset($session[0]) ;
$sessions = array();
foreach ($session as $key => $value) {
$session[$key] = explode(" ", $value) ;
//print_array($session[$key]);
$sessions[] = array($session[$key][0],$session[$key][1]) ;
}
$sessions = json_encode($sessions, JSON_NUMERIC_CHECK) ;
?>
<div id="collapse_awstats_extract_session" class="accordion-body collapse in">
<div class="accordion-inner">
<div id="chart-session" style="height:350px; width:700px; margin:0 auto;"></div>
</div>
</div>
<script>
jQuery(document).ready(function(){
var data = <?php echo $sessions; ?>;
var plot1 = jQuery.jqplot('chart-session', [data], {
title: 'Durée des visites',
seriesDefaults: {
renderer: jQuery.jqplot.PieRenderer,
rendererOptions: {
showDataLabels: true,
},
},
legend: { show:true, location: 'e' },
});
});
</script>
And there's a function that calls that previous one :
<?php
echo '<div class="accordion-group">';
preg_match("/BEGIN_SESSION(.*)END_SESSION/is", $awstats, $matches);
$session = $matches[0];
preg_match('/30s-2mn ([0-9]{2})/ms', $session, $matches);
$a = $matches[1];
preg_match('/0s-30s ([0-9]{3})/ms', $session, $matches);
$b = $matches[1];
var_dump($a+$b);
awstats_title("<a class='accordion-toggle' data-toggle='collapse' data-parent='#accordion_awstats_navigation' href='#collapse_awstats_extract_session'><span class='glyphicon glyphicon-collapse-down'></span> Durée des visites</a>", "session") ;
awstats_extract_session($session) ;
And i would like that display all it content but the last two "30s-2mn 35" "0s-30s 170" I'd like to diplay it as "0s-2mn 205".Please Help P.S: Or is there a way to change the file "test.txt" in such to have "test2.txt":
BEGIN_SESSION 7
1h+ 47
30mn-1h 20
15mn-30mn 16
5mn-15mn 43
2mn-5mn 29
0s-2mn 205
END_SESSION
Thanks!
解决方案
Hope this helps.
preg_match("/BEGIN_SESSION(.*)END_SESSION/is", $test, $matches);
$session = $matches[0];
preg_match('/30s-2mn ([0-9]{2})/ms', $session, $matches);
$a = $matches[1];
preg_match('/0s-30s ([0-9]{3})/ms', $session, $matches);
$b = $matches[1];
$session = preg_replace('/30s-2mn ([0-9]{2})\n0s-30s ([0-9]{3})/ms', "0s-2mn " . ($a+$b), $session);
Then $session contains the text you showed in the last code example in your question. To write it out you could do.
$session now contains:
BEGIN_SESSION 7
1h+ 47
30mn-1h 20
15mn-30mn 16
5mn-15mn 43
2mn-5mn 29
0s-2mn 205
END_SESSION
