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
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 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. PHP also contains an built-in web
server for application development purpose. By using the -S option
where addr:port point to a local address and port PHP will listen to
HTTP requests on that address and port and serve files from the
current working directory or the docroot passed by the -t option. If
a PHP file is provided to the command line when the built-in web
server is used, it will be used as the router script. This script will
be started at each HTTP request. The script output is returned to the
browser, unless the router script returns the false value. If so, the
built-in server falls back to the default behaviour, returning the
requested resource as-is by looking up the files relative to the
document root specified by the -t option, if provided. If none of -r
-f -B -R -F -E or -S 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.
--bindpath address:port|port
-b address:port|port
Bind Path for external FASTCGI Server mode (CGI only).
--no-chdir
-C Do not chdir to the script's directory (CGI only).
--no-header
-q Quiet-mode. Suppress HTTP header output (CGI only).
--timing count
-T count Measure execution time of script repeated count times
(CGI only).
--php-ini path|file
-c path|file Look for php.ini file in the directory path or use the
specified file
--no-php-ini
-n No php.ini file will be used
--define foo[=bar]
-d foo[=bar] Define INI entry foo with value bar
-e Generate extended information for debugger/profiler
--file file
-f file Parse and execute file
--help
-h This help
--hide-args
-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.
--info
-i PHP information and configuration
--syntax-check
-l Syntax check only (lint)

FILES
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.
EXAMPLES
php -r 'echo "Hello World0;'
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)."0;'
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: $argi0;'
Using this PHP command you can count the lines being input.
php -R '@$l+=count(file($argn));' -E 'echo "Lines:$l0;'
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 "$argn0; 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.
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
<?php
// your script
?>
