PHP勉強会はどのくらいの早さで枠が埋まるのか

下みたいな感じでtimestampの差とる形でうんにゃこりゃやってたんだけど、

なんか色んな意味でダメだなあ。

<?php
$csv = "./phpgrEventTimeStamp.csv";
require_once "/library/Diggin/Scraper/Simple.php";
require_once "/library/Diggin/Console/Interactive.php";
$scraper = new Diggin_Scraper_Simple();
$console = new Diggin_Console_Interactive();

	
//http://events.php.gr.jp/event.php/event_show/の最後のイベントの末尾取得
$scraper->setUrl("http://events.php.gr.jp/event.php");
$events = $scraper->getAttribute('//div[@id="content"]/div[2]//p/a', "href");
$eventNum = (int)str_replace("http://events.php.gr.jp/event.php/event_show/","",$events[0]);


require_once "Zend/Filter.php";
require_once "/library/Diggin/Filter/Num.php";
$filterChain = new Zend_Filter();
$filterChain->addFilter(new Diggin_Filter_Num());


//各イベントの処理

for ($n = 1; $n <=  $eventNum; $n++)
{
	$scraper->setUrl("http://events.php.gr.jp/event.php/event_show/".$n);
	$content = $scraper->scrape('//div[@id="content"]');
	
	//第○回
	print_r($filterChain->filter($content[0]->div[1]->h2[0]));
	echo "\n";
	
	//日時
	//$content[0]->div[1]->dl[0]->dd[0]->div[1]->p[0]
	
	$eventDate = $filterChain->filter($content[0]->div[1]->dl[0]->dd[1]);
	$eventDate8 = substr($eventDate, 0 , 8);
	echo $eventDate8."\n";
	
	//参加者数
	$i = 0;
	$putFlag = FALSE;
	foreach(($content[0]->ul[1]->li) as $cont) {
		if ($i == 0) {
			echo "boshu Ninzuu"."\n";
			$boshuNum = (int)$filterChain->filter($cont);
		} elseif($i == 1) {
			echo "sanka Ninzuu"."\n";
			$sankaNum = (int)$filterChain->filter($cont);
		}
		
		echo $filterChain->filter($cont);
		echo "\n";
		$i = $i + 1;
	}
	
	//参加人数を見てput判断
	if ($console->yesNo("put?")) {
		$member = $scraper->scrape('//div[@id="content"]//div[@align="center"]//table');
		$firster = $member[0]->tr[1]->td[2];
		//$countMember = count($member[0]->tr);
		//echo $countMember;
		if($sankaNum < $boshuNum){
			$laster = $member[0]->tr[$sankaNum]->td[2];
		} else {
			$laster = $member[0]->tr[$boshuNum]->td[2];
		}
		//echo $laster;
		
		require_once 'Zend/Date.php';
		$date = new Zend_Date($firster, 'YYYY.MM.dd.hh.mm.ss');
		$firsterStamp = $date->getTimestamp();
		$date = new Zend_Date($laster, 'YYYY.MM.dd.hh.mm.ss');
		$lasterStamp = $date->getTimestamp();
		$diff = $lasterStamp - $firsterStamp;
		
		$putText = $eventDate8.",".$diff."\n";
		file_put_contents($csv, $putText, FILE_APPEND);
	}
	
	echo "----------------------";
