php数组的重复值如何过滤掉

Question

我的脚本有一些问题。问题是：

打印输出时，$ str或@matchedPath的值有时会为空白。它不是随机的，只发生在table.txt文件中的某些Path，我无法弄明白，为什么？
如何打印结果，因为我找不到table.txt文件的正确文件位置或目录，因为我已将所有路径位置放在一个数组中，过滤它并与table.txt匹配的正确文件位置进行比较因此，打印出来时会丢失一些位置。

/home/is/latest/table.txt文件包含的示例路径，粗体文本是table.txt中的所需路径，

##WHAT PATH IS_THAT,Backup
a   b/c/d   B
a   b/c/d/e  B
a   b/c/d/e/f  B
a   b/c/d/g  B

/home/are/latest/table.txt文件包含的示例路径，中间文本是table.txt中的有用路径，

##WHAT PATH IS_THAT,Backup
a   b/c/d/j B

例如list.txt文件包含，

rty/b
uio/b/c
qwe/b/c/d
asd/b/c/d/e
zxc/b/c/d/e/f
vbn/c/d/e
fgh/j/k/l

预期结果：

Unmatched Path         : b/c/d/g
table.txt file location: /home/is/latest/table.txt

Unmatched Path         : b/c/d/j
table.txt file location: /home/are/latest/table.txt

下面是我的详细脚本，

#!/usr/perl/5.14.1/bin/perl 

# I want to make a script that automatically compare the path in table.txt with list.txt
#table.txt files is located under a parent directory and it differs in the subdirectory.
#There is about 10 table.txt files and each one of it need to compare with list.txt
#The objective is to print out the path that are not in the list.txt

php数组的重复值如何过滤掉

将所有数据保存在数组中，过滤掉重复的数据，比较数组之间的数据并删除匹配的数据
