PHP is a widely used general purpose scripting language that is espe
cially 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 exe
cuted. You can access the input line by $argn. While processing the
input lines $argi contains the number of the actual line being pro
cessed. 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.

a Run PHP interactively. This lets you enter snippets of
PHP code that directly get executed. When readline sup
port is enabled you can edit the lines and also have
history support.

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

global name
g name Make variable name global in script.

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.

i PHP information and configuration

syntax check
l Syntax check only (lint)

m Show compiled in modules

run code
r code Run PHP code without using script tags ''

process begin code
B code Run PHP code before processing input lines

process code code
R code Run PHP code for every input line

process file file
F file Parse and execute file for every input line

process end code
E code Run PHP code after processing all input lines

syntax highlight
s Output HTML syntax highlighted source

v Version number

w Output source with stripped comments and whitespace

zend extension file
z file Load Zend extension file

args... Arguments passed to script. Use ' ' args when first
argument starts with ' ' or script is read from stdin

rfunction name
rf name Shows information about function name

rclass name
rc name Shows information about class name

rextension name
re name Shows information about extension name

rextinfo 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
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)."
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 follow
ing 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
Using this PHP command you can count the lines being input.

php R '@$l+=count(file($argn));' E 'echo "Lines:$l
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
"; 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: skip
ping 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
