删数组有得有重复值
有原数组a 里有值 $a=array(a,b,c);
比较数组b 里有值 $b=array(b);

两个相比较,得到$c= array(a,c);

请问一下,这个怎么做。

------解决方案--------------------
循环判断或者移除呗
------解决方案--------------------
用array_diff ($array_a,$array_b)

Replace svn diff with vimdiff: a tool for comparing code Replace svn diff with vimdiff: a tool for comparing code Jan 09, 2024 pm 07:54 PM

It is very convenient. When using the svndiff command to compare the modifications of a certain file, for example, if you execute the following command: $svndiff-r4420ngx_http_limit_req_module.c, the following command will actually be sent to the default diff program: -u-Lngx_http_limit_req_module.c(revision4420)-Lngx_

How to use the Array module in Python How to use the Array module in Python May 01, 2023 am 09:13 AM

The array module in Python is a predefined array, so it takes up much less space in memory than a standard list, and can also perform fast element-level operations such as adding, deleting, indexing, and slicing. In addition, all elements in the array are of the same type, so you can use the efficient numerical operation functions provided by the array, such as calculating the average, maximum, and minimum values. In addition, the array module also supports writing and reading array objects directly into binary files, which makes it more efficient when processing large amounts of numerical data. Therefore, if you need to process a large amount of homogeneous data, you may consider using Python's array module to optimize the execution efficiency of your code. To use the array module, you first need to
