Usage

Overview

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.

If none of -r or -f 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

-a

Run interactively

-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

-h

This help

-i

-l

-m

-r code

-s

-v

-w

-z file

Files

/etc/php4/cli/php.ini

The configuration file for the CLI version of PHP.

/etc/php4/cgi/php.ini

The configuration file for the CGI version of PHP.

/etc/php4/apache/php.ini

The configuration file for the version of PHP that apache uses.

/etc/php4/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 imag 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));'

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:
