Introduction to php command line usage, php command line usage

Php is a very popular web server scripting language. In fact, php can not only play an important role in the web server. It can also be executed from the command line.

In this article, the author will introduce to you how to use php in the command line .

1. Check the version and configuration of php

Enter php -v on the command line to view the current php version.

  10. Other options are: –m, -i. The author will not give any examples here.

-m will display the valid modules currently loaded by php.

-i outputs phpinfo without html format.

Use the –ini option to output the number and path information of the ini configuration files currently loaded by php.

2. Run the php program in the command line

Running php from the command line is very easy. But there are some precautions that you need to understand. Server variables such as $_SESSION cannot be used in the command line, and other code runs exactly the same as in the web server^_^.

Php code

Introduction to php command line usage, php command line usage_PHP tutorial
  • echo “Run php command line
  • echo”; ?>
  • Save the above code as hello.php. Type php –f hello.php at the command line. The displayed results are as follows:


    One of the benefits of executing php files on the command line is that you can execute some scheduled tasks through scripts. No need to go through the web server^_^.

    Of course, we can also debug the code directly in php: enter the php -r command, and a ">" symbol will appear. This means that you have entered the PHP shell and can write code directly and execute it.

    Java code

    Introduction to php command line usage, php command line usage_PHP tutorial-bash-
      3.2$ php -r '
    1. >
    2. for($i=
    3. 0;$i2;$i++){ > echo
    4. "Number: {$i}n";
    5. > }
    6. > '
    7. Number:
    8. 0
    9. Number:
    10. 1

    You can also use the php –a command to open the interactive mode, enter a line of code, and php will output the results in real time.

    3. Detect PHP syntax and highlight output

    Without executing code, we can detect syntax errors in php files from the command line.

    Java code

    Introduction to php command line usage, php command line usage_PHP tutorial-bash-
      3.2$ php -l hello.php
    1. No syntax errors detected in hello.php

    程序员经常会需要将php代码高亮原样输出,使用php –s 即可

    Java代码  Introduction to php command line usage, php command line usage_PHP tutorial
    1. -bash-3.2$ php -s hello.php  
    2. <span class="string">"color: #000000">  </span>
    3. "color: #0000BB">
    4. "color: #007700">echo
    5. "color: #DD0000">'ddd'
    6. "color: #007700">;
    7. style="color: #0000BB">?>

    4、查看php手册

    从php5.1.2开始,程序员们可以在php命令行下查看手册了,输入php –rf function。会打印出该函数的语法简介

    Java代码  Introduction to php command line usage, php command line usage_PHP tutorial
    1. -bash-3.2$ php --rf strip_tags  
    2. Function [  function strip_tags ] {  
    3.    
    4. - Parameters [2] {

    6. Parameter #1 [  $allowable_tags ]  
    7. }  
    8. }  

     

    如果要查看类使用 –rc;查看扩展使用 –re。

    php - Unix, Linux Command

     

    NAME

    php - PHP Command Line Interface ’CLI’

     

    SYNOPSIS

    php [options] [ -f ] file [[--] args...]

    php [options] -r code [[--] args...]

    php [options] [-B code-R code [-E code] [[--] args...]

    php [options] [-B code-F file [-E code] [[--] args...]

    php [options] -- [ args...]

    php [options] -a

     

    DESCRIPTION

    PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. This is the command line interface that enables you to do the following:

    You can parse and execute files by using parameter -f followed by the name of the file to be executed.

    Using parameter -r you can directly execute PHP code simply as you would do inside a .php file when using theeval() function.

    It is also possible to process the standard input line by line using either the parameter -R or -F. In this mode each separate input line causes the code specified by -R or the file specified by -F to be executed. You can access the input line by $argn. While processing the input lines $argi contains the number of the actual line being processed. Further more the parameters -B and -E can be used to execute code (see -r) before and after all input lines have been processed respectively. Notice that the input is read from STDIN and therefore reading from STDIN explicitly changes the next input line or skips input lines.

    If none of -r -f -B -R -F or -E is present but a single parameter is given then this parameter is taken as the filename to parse and execute (same as with -f). If no parameter is present then the standard input is read and executed.

     

    OPTIONS

    Tag Description

    --interactive

    FILES

     

    Tag Description

    php-cli.ini The configuration file for the CLI version of PHP.
    php.ini The standard configuration file will only be used when php-cli.ini cannot be found.

    php-cli.ini

    The configuration file for the CLI version of PHP.

    php -r ’echo "Hello Worldn";’
      This command simply writes the text "Hello World" to standard out.
    php -r ’print_r(gd_info());’
      This shows the configuration of your gd extension. You can use this to easily check which image formats you can use. If you have any dynamic modules you may want to use the same ini file that php uses when executed from your webserver. There are more extensions which have such a function. For dba use:php -r ’print_r(dba_handlers(1));’
    php -R ’echo strip_tags($argn)."n";’
      This PHP command strips off the HTML tags line by line and outputs the result. To see how it works you can first look at the following PHP command 'php -d html_errors=1 -i' which uses PHP to output HTML formatted configuration information. If you then combine those two 'php ...|php ...' you’ll see what happens.
    php -E ’echo "Lines: $argin";’
      Using this PHP command you can count the lines being input.
    php -R ’@$l+=count(file($argn));’ -E ’echo "Lines:$ln";’
      In this example PHP expects each input line being a file. It counts all lines of the files specified by each input line and shows the summarized result. You may combine this with tools like find and change the php scriptlet.
    php -R ’echo "$argnn"; fgets(STDIN);’
      Since you have access to STDIN from within -B -R -F and -E you can skip certain input lines with your code. But note that in such cases $argi only counts the lines being processed by php itself. Having read this you will guess what the above program does: skipping every second input line.
    php.ini The standard configuration file will only be used when php-cli.ini cannot be found.   EXAMPLES   Tag Description php -r ’echo "Hello Worldn";’

But note that in such cases $argi only counts the lines being processed by php itself. Having read this you will guess what the above program does: skipping every second input line.

     

    TIPS

    You can use a shebang line to automatically invoke php from scripts. Only the CLI version of PHP will ignore such a first line as shown below:

    #!/bin/php

    // your script

    ?>

    How to use the sys module to obtain command line parameters in Python 2.x How to use the sys module to obtain command line parameters in Python 2.x Jul 31, 2023 pm 07:01 PM

    Python is a flexible and easy-to-use programming language that provides many modules for operating systems and command lines. One of them is the sys module, which provides us with some tools to handle command line parameters. In this article, we will learn how to get command line arguments in Python2.x using the sys module. First, we need to understand that the sys module is part of the Python standard library, so there is no need to install additional packages. We just need to import the sys module at the beginning of the code: imp

    Example of command line parameters in C language Example of command line parameters in C language Aug 30, 2023 pm 03:09 PM

    When executing C programs, some values ​​can be passed to them from the command line. These values ​​are called command line parameters, and many times they are important to your program, especially when you want to control the program from the outside rather than hardcoding these values ​​within the code. Command line parameters are processed using main() function parameters, where argc refers to the number of parameters passed, and argv[] is an array of pointers to each parameter passed to the program. Here is a simple example that checks if there are any arguments supplied from the command line and takes action accordingly - Example code #include<stdio.h>intmain(intargc,char*argv[]){ &nb

    In C language, command line parameters refer to parameters passed to the program through the command line when the program is running. In C language, command line parameters refer to parameters passed to the program through the command line when the program is running. Sep 22, 2023 pm 03:01 PM

    Executable instructions that perform operating system tasks are called commands. These commands are issued from the operating system prompt. The parameters associated with the command are as follows: argc - argument count. argv - Argument vector. argc - It holds the total number of arguments passed from the command prompt. argv - It is a pointer to a character string array containing the names of the arguments. For example: c:|>sample.Exehellohowareyou arguments here, argc=5argv[0]=sample.exeargv[1]=helloargv[2]=howargv[3]=arear
