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
Using parameter -r you can directly execute PHP code simply as you would do inside a .php
file when using the eval() 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 pro-
cessing the input lines $argi contains the number of the actual line being processed. Fur-
ther 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
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.
-a Run PHP interactively. This lets you enter snippets of PHP code that
directly get executed. When readline support is enabled you can edit the
lines and also have history support.
Bind Path for external FASTCGI Server mode (CGI only).
-C Do not chdir to the script's directory (CGI only).
-q Quiet-mode. Suppress HTTP header output (CGI only).
-T count Measure execution time of script repeated count times (CGI only).
-c path|file Look for php.ini file in the directory path or use the specified file
-n No php.ini file will be used
-d foo[=bar] Define INI entry foo with value bar
-e Generate extended information for debugger/profiler
-f file Parse and execute file
-g name Make variable name global in script.
-h This help
-H Hide script name (file) and parameters (args...) from external tools. For
example you may want to use this when a php script is started as a daemon
and the command line contains sensitive data such as passwords.
-i PHP information and configuration
-l Syntax check only (lint)
-m Show compiled in modules
-r code Run PHP code without using script tags '<?..?>'
-B code Run PHP code before processing input lines
-R code Run PHP code for every input line
-F file Parse and execute file for every input line
-E code Run PHP code after processing all input lines
-s Output HTML syntax highlighted source
-v Version number
-w Output source with stripped comments and whitespace
-z file Load Zend extension file
args... Arguments passed to script. Use '--' args when first argument starts with
'-' or script is read from stdin
--rf name Shows information about function name
--rc name Shows information about class name
--re name Shows information about extension name
--ri name Shows configuration for extension name
--ini Show configuration file names
The configuration file for the CLI version of PHP.
The configuration file for the CGI version of PHP.
The configuration file for the version of PHP that apache2 uses.
php -r 'echo "Hello World\n";'
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: $argi\n";'
Using this PHP command you can count the lines being input.
php -R '@$l+=count(file($argn));' -E 'echo "Lines:$l\n";'
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 "$argn\n"; 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.
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:
// your script
