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.
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.
OPTIONS
--interactive
-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.
--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.
--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)
--modules
-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
--version
-v Version number
--stripped
-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
FILES
/etc/php5/cli/php.ini
The configuration file for the CLI version of PHP.
/etc/php5/cgi/php.ini
The configuration file for the CGI version of PHP.
/etc/php5/apache2/php.ini
The configuration file for the version of PHP that apache2 uses.
EXAMPLES
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 exe‐
cuted 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.
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
?>
