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？
回复讨论(解决方案) 如果是这样呢？
foreach (glob($datapath./ng/*.csv) as $filename) { preg_match('/.+\/(\d+)/',$filename,$match); echo $value_lotno.'=>'.$match[1].'
'; }
求得结果：
5106=>80015127=>72075127=>72075306=>70205306=>70205306=>70205306=>70205306=>70205306=>70205309=>71735309=>71735310=>71025310=>71025310=>72535310=>72535310=>74345310=>74345310=>74435310=>74435310=>75085310=>75085310=>75735310=>7573
如何把这个结果变成一个数组，像这样的形式：
array('5106=>8001','5127=>7207','5306=>7020','5309=>7173','5310=>7102','5310=>7253','5310=>7434','5310=>7443','5310=>7508','5310=>7573');
$arr=array( '5106=>8001', '5127=>7207', '5127=>7207', '5306=>7020', '5306=>7020', '5306=>7020', '5306=>7020', '5306=>7020', '5306=>7020', '5309=>7173', '5309=>7173', '5310=>7102', '5310=>7102', '5310=>7253', '5310=>7253', '5310=>7434', '5310=>7434', '5310=>7443', '5310=>7443', '5310=>7508', '5310=>7508', '5310=>7573', '5310=>7573',);echo ;print_r(array_values(array_unique($arr)));echo
;/*array( [0] => 5106=>8001 [1] => 5127=>7207 [2] => 5306=>7020 [3] => 5309=>7173 [4] => 5310=>7102 [5] => 5310=>7253 [6] => 5310=>7434 [7] => 5310=>7443 [8] => 5310=>7508 [9] => 5310=>7573)*/
$arr=array( '5106=>8001', '5127=>7207', '5127=>7207', '5306=>7020', '5306=>7020', '5306=>7020', '5306=>7020', '5306=>7020', '5306=>7020', '5309=>7173', '5309=>7173', '5310=>7102', '5310=>7102', '5310=>7253', '5310=>7253', '5310=>7434', '5310=>7434', '5310=>7443', '5310=>7443', '5310=>7508', '5310=>7508', '5310=>7573', '5310=>7573',);echo ;print_r(array_values(array_unique($arr)));echo

不对吧。原来的格式不是数组啊，我是要把原来的格式变成数组啊。
你不都循环出来了吗.....
echo $value_lotno.'=>'.$match[1].'
';
下面加上
$arr[]=$value_lotno.'=>'.$match[1];
这样就行了

是我的问题，应该放在循环外面print_r，但是这问题问的已经和我的本意相去甚远了，我本来想问的是，如1#的路径，把路径最后的7020开头的文件都作为1个文件来看，计算出ng文件夹下的文件数量为1，这个要怎么求？
举个例子来看！
举个例子来看！
$datapath = '../../dat/dig/testfunction/'.$machine.'/'.$value_type.'/'.$value_lotno;//已求得var_dump(glob($datapath.'/ng/*.*', glob_brace));
得到如下结果：
array(1) { [0]=> string(62) ../../dat/dig/testfunction/ts407/bed410-500a1/5106/ng/8001.csv}array(2) { [0]=> string(62) ../../dat/dig/testfunction/ts407/bed410-500a1/5127/ng/7207.csv [1]=> string(65) ../../dat/dig/testfunction/ts407/bed410-500a1/5127/ng/7207_ng.csv}array(0) {}array(0) {}array(6) { [0]=> string(62) ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020.csv [1]=> string(64) ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_1.csv [2]=> string(64) ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_2.csv [3]=> string(64) ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_3.csv [4]=> string(64) ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_4.csv [5]=> string(65) ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_ng.csv}
想要得到的这些路径下对应的ng的结果数量。（如果开头都一样的话则作为一个文件）
$arr=array( ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_1.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_2.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_3.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_4.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_ng.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7021_ng.csv,//添加测试);foreach($arr as $v){ $tmp=explode('/',$v); $lastfile=array_pop($tmp); preg_match('/^(\d+)(\.|\_)/',$lastfile,$m); $arr_file[]=$m[1];}$count=count(array_unique($arr_file));echo $count;//2
$arr=array( ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_1.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_2.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_3.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_4.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7020_ng.csv, ../../dat/dig/testfunction/ts407/bed410-500a1/5306/ng/7021_ng.csv,//添加测试);foreach($arr as $v){ $tmp=explode('/',$v); $lastfile=array_pop($tmp); preg_match('/^(\d+)(\.|\_)/',$lastfile,$m); $arr_file[]=$m[1];}$count=count(array_unique($arr_file));echo $count;//2
如果有像7#的空数组这样就不对了，变成了1.
唉，二维你就判断一下就行了嘛

我不要求总和，求分项的和：1,1,2
请问怎么求？ 我是醉了，能一次说完么，哥
$count=count(array_unique($arr_file));
改为
$new=array_count_values($arr_file);
