已知数组a的形式，如果把7020开头的文件看作一个文件，求得这样的结果:ts407,bed410-500a1,5306,ng对应数量为1.这要怎么求？
------解决思路----------------------

<br />$arr=array(<br />	"../../dat/DIG/TestFunction/TS407/BED410-500A1/5306/NG/7020.csv",<br />	"../../dat/DIG/TestFunction/TS407/BED410-500A1/5306/NG/7020_1.csv",<br />	"../../dat/DIG/TestFunction/TS407/BED410-500A1/5306/NG/7020_2.csv",<br />	"../../dat/DIG/TestFunction/TS407/BED410-500A1/5306/NG/7020_3.csv",<br />	"../../dat/DIG/TestFunction/TS407/BED410-500A1/5306/NG/7020_4.csv",<br />	"../../dat/DIG/TestFunction/TS407/BED410-500A1/5306/NG/7020_NG.csv",<br />	"../../dat/DIG/TestFunction/TS407/BED410-500A1/5306/NG/7021_NG.csv",//添加测试<br />);<br />foreach($arr as $v){<br />	$tmp=explode('/',$v);<br />	$lastfile=array_pop($tmp);<br />	preg_match('/^(\d+)(\.<br><font color='#FF8000'>------解决思路----------------------</font><br>\_)/',$lastfile,$m);<br />	$arr_file[]=$m[1];<br />}<br />$count=count(array_unique($arr_file));<br />echo $count;//2<br />
