php PHP Command Line Interface βCLIβ
php [options] [ -f ] file [[--] args...]

php [options] -- [ args...]
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 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 paramters -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
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 interactively
-c path|file Look for php.ini file in the directory path or use the
-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 ββ<?..?>ββ
-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 Display colour syntax highlighted source
-v Version number
-w Display source with stripped comments and whitespace
-z file Load Zend extension file
args... Arguments passed to script. Use ββ--ββ args when first
argument starts with ββ-ββ or script is read from stdin
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 -r βecho "Hello World\n";β
This command simply writes the text "Hello World" to standard out.
php -r βprint_r(gd_info());β
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 βprint_r(dba_handlers(1));β
php -R βecho strip_tags($argn)."\n";β
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 Β΄php -d html_errors=1 -iΒ΄ which uses PHP to
output HTML formatted configuration information. If you then com-
bine those two Β΄php ...|php ...Β΄ youβll see what happens.
php -E βecho "Lines: $argi\n";β
Using this PHP command you can count the lines being input.
php -R β@$l+=count(file($argn));β -E βecho "Lines:$l\n";β
In this example PHP expects each input line beeing 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 βecho "$argn\n"; fgets(STDIN);β
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
// your script

of contributors all around the world.
