能否通过cmd不打开JuliaStudio应用而执行jl文件呢?
问题:
最近项目上遇到一个问题,一开始想用PHP语言通过cmd打开julia的REPL环境运行一个jl文件,但是不成功。命令行下运行php文件就可以,但是浏览器就是不行。具体问题感兴趣的可以参见我之前的提问---->链接地址。
考虑到可能调用julia的REPL环境有别于普通的软件,所以打开不顺利,现在转换思路,尝试用另一个方法:
看到PHP可以通过CMD调用的MATLAB来运行m文件,无论是浏览器运行php文件,还是命令行运行php文件,均可以完美实现。只需要在php文件中使用一个命令:
exec('matlab -nodesktop -minimize -r test')就行了。其中test是matlab的m文件。这样我就不需要打开matlab软件就可以运行m文件,实现运算。
同样,我现在考虑如何用JuliaStudio在命令行下运行jl文件,但是百度谷歌了一同之后并没有找到JuliaStudio类似于Matlab命令行中的“-r”之类的运行参数。求问各位Julia使用达人,是否有什么参数可以从CMD调用JuliaStudio软件直接运行指定的m文件的呢?
方法:
如果你的julia没有加入环境变量path,需要在cmd中执行
julia安装路径/julia.exe 你的*.jl路径/xxx.jl
如果已经加入环境变量,可以简化成:
julia.exe 你的*.jl路径/xxx.jl
如果是windows ,在jl文件上右键打开方式,选择一直用julia.exe打开.
以后每次双击运行,是也可以的.但是需要在代码后面加上暂停代码,不然看不到输出结果,
run(`cmd /c pause`)
或者直接在cmd 中输入你的*.jl路径/xxx.jl 回车.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
