.SH DESCRIPTION
\fBPHP\fP 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:
.P
You can parse and execute files by using parameter \-f followed by the name of the
.IR file
to be executed.
.LP
Using parameter \-r you can directly execute PHP
.IR code
simply as you would do inside a
.B \.php
file when using the
.B eval()
function.
.LP
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
.IR code
specified by \-R or the
.IR file
specified by \-F to be executed.
You can access the input line by \fB$argn\fP. While processing the input lines
.B $argi
contains the number of the actual line being processed. Further more
the parameters \-B and \-E can be used to execute
.IR code
(see \-r) before and
after all input lines have been processed respectively. Notice that the
input is read from
.B STDIN
and therefore reading from
.B STDIN
explicitly changes the next input line or skips input lines.
.LP
PHP also contains an built-in web server for application development purpose. By using the \-S option where
.B 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
.B docroot
passed by the \-t option.
.LP
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.

.SH FILES
.TP 15
.B php\-cli.ini
The configuration file for the CLI version of PHP.
.TP
.B php.ini
The standard configuration file will only be used when
.B php\-cli.ini
cannot be found.
.SH EXAMPLES
.TP 5
\fIphp \-r 'echo "Hello World\\n";'\fP
This command simply writes the text "Hello World" to standard out.
.TP
\fIphp \-r 'print_r(gd_info());'\fP
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:
.RS
\fIphp \-r 'print_r(dba_handlers(1));'\fP
.RE
.TP
\fIphp \-R 'echo strip_tags($argn)."\\n";'\fP
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
\'\fIphp \-d html_errors=1 \-i\fP\' which uses PHP to output HTML formatted
configuration information. If you then combine those two
\'\fIphp \.\.\.|php \.\.\.\fP\' you'll see what happens.
.TP
\fIphp \-E 'echo "Lines: $argi\\n";'\fP
Using this PHP command you can count the lines being input.
.TP
\fIphp \-R '@$l+=count(file($argn));' \-E 'echo "Lines:$l\\n";'\fP
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.
.TP
\fIphp \-R 'echo "$argn\\n"; fgets(STDIN);'\fP
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.
.SH 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:
.P
.PD 0
.RS
#!/bin/php
.P
<?php
.P
 // your script
.P
?>
