piping data into command line php?

php command line arguments
php command line input
php://stdin
php cmd shell
php echo to command line
php stdin to array
run php code from command line
php popen

It is possible to pipe data using unix pipes into a command-line php script? I've tried

$> data | php script.php

But the expected data did not show up in $argv. Is there a way to do this?

As I understand it, $argv will show the arguments of the program, in other words:

php script.php arg1 arg2 arg3

But if you pipe data into PHP, you will have to read it from standard input. I've never tried this, but I think it's something like this:

$fp = readfile("php://stdin");
// read $fp as if it were a file

Processing data with PHP using STDIN and Piping, By using a pipe in Linux, we could use the zcat command and pipe in the to filter the compressed data as well, you could use zgrep and filter those lines out  You'll notice that when we ran wc supplying the file to process as a command line argument, the output from the program included the name of the file that was processed. When we ran it redirecting the contents of the file into wc the file name was not printed. This is because whenever we use redirection or piping, the data is sent anonymously.

PHP can read from standard input, and also provides a nice shortcut for it: STDIN.

With it, you can use things like stream_get_contents and others to do things like:

$data = stream_get_contents(STDIN);

This will just dump all the piped data into $data.

If you want to start processing before all data is read, or the input size is too big to fit into a variable, you can use:

while(!feof(STDIN)){
    $line = fgets(STDIN);
}

STDIN is just a shortcut of $fh = fopen("php://stdin", "r");. The same methods can be applied to reading and writing files, and tcp streams.

Using PHP from the command line, Description ¶. popen ( string $command , string $mode ) : resource. Opens a pipe to a process executed by forking the command given by command . One of the things I like about perl and vbscripts, is the fact that I can name a file e.g. 'test.pl' and just have to type 'test, without the .pl extension' on the windows command line and the command processor knows that it is a perl file and executes it using the perl command interpreter.

If your data is on one like, you can also use either the -F or -R flag (-F reads & executes the file following it, -R executes it literally) If you use these flags the string that has been piped in will appear in the (regular) global variable $argn

Simple example:

echo "hello world" | php -R 'echo str_replace("world","stackoverflow", $argn);'

popen - Manual, The command line interface data in STDIN is not made available until return is awaiting input from the user, which isn't useful as we're looking for a piped file. When a command is piped with ' | batch_command ' this will instantiate a new CMD.exe instance, in effect running: C:\Windows\system32\cmd.exe /C /S /D "batch_command" This has several side effects: Any newline characters in the batch_command will be turned into & operators. (see StackOverflow)

You can pipe data in, yes. But it won't appear in $argv. It'll go to stdin. You can read this several ways, including fopen('php://stdin','r')

There are good examples in the manual

I/O streams - Manual, proc_open ( mixed $cmd , array $descriptorspec , array &$pipes [, string $cwd = NULL [, array $env You may even write some data into it (into shell, actually). The above redirection operator examples are within the context of Command Prompt, but you can also use them in a BAT file. When you use a BAT file to pipe a command's output to a text file, the exact same commands described above are used, but instead of pressing Enter to run them, you just have to open the .BAT file.

This worked for me:

stream_get_contents(fopen("php://stdin", "r"));

proc_open - Manual, Using popen to pipe command line commands within PHP. The function "​proc_open" behaves the same as popen, but gives you access to not secure is that you cannot trust any data, no matter where it comes from: OCR  Perl shell command pipeline example - reading the date. Here's a simple example of running a system command (shell command) and reading the output of the command in your Perl script. The Unix date command prints the system date and time. Running it at the command line, you get output that looks something like this: Sun Jul 12 16:55:51 EDT 1998

popen for cli commands and pipes in php, Maybe I get empty CMD console, but php did'nt run the script. Thats true, but my problem is, that PHP don't find the PIPE Data from "Write  some_command | tee command.log and some_command > command.log have the issue that they do not save the command output to the command.log file in real-time. To avoid that issue and save the command output in real-time, you may append unbuffer , which comes with the expect package.

Looking for a sample to execute PHP using Execute Program , n\";" | findstrolleh In this line of code, you pipe the contents of a text file into PHP. to fit comfortably on the command line, you can put the code in a normal PHP that file is called on each line (each $argn) from the data file (data.txt): ~$ php  Pipes '|' send the output of one command as input of another command. The Filter takes input from one command, does some processing, and gives output. The grep command can be used to find strings and values in a text document; Piping through grep has to be one of the most common uses 'sort' command sorts out the content of a file alphabetically

PHP Beyond the Web, Create Command Line Interface Scripts with PHP Rob Aley For instance, to reverse every line of a file (or any data source that you pipe into it), on Linux or OS  (cat file.txt ; echo "My final line") | other command works as is expected – all the output from the subshell formed by the parentheses is piped to the second command. If the file doesn't end with a new line, the echoed string is appended to the last line – this is common with all the other solutions here, and can be solved by adding

Comments
  • See as well: Detect if a PHP script is being run interactively or not
  • If you replace "readfile" with "file", you'll get the input as an array of lines and it won't be automatically echoed.
  • This works and you don't need to read from stdin. I think this should be marked.
  • Note that -R will read one line at a time, and execute all of the code for each line.
