php -r ’echo "Hello World\n";’
This command simply writes the text "Hello World" to standard
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)."\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
php -E ’echo "Lines: $argi\n";’
Using this PHP command you can count the lines being input.
php -R ’@$l+=count(file($argn));’ -E ’echo
In this example PHP expects each input line being a file. It
counts all lines of the files specified by each input line and
shows the summarized result. You may combine this with tools like
find and change the php scriptlet.
php -R ’echo "$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.
Making Apache use compiled PHP instead of bundled package on Debian
Debian can actually help you here--
apt-get has a
mode for downloading the source and build-dependencies for a
package, which you can then tweak and build yourself. In theory,
the setup should be identical to what Debian's repository
contains, so it ought to integrate well with your version of
I originally found this is PHP Magazine where they used it to
customize the version of GD they were compiling with PHP. But you
could use it for changing other build flags just as easily.
Since the original site isn't available any more (link above is
through the Way Back Machine), I'm reproducing the instructions
# Install build tools, debian helpers and fakeroot
apt-get install build-essential debhelper fakeroot
# Get PHP source (it should go into /usr/src)
apt-get source php5
# Install all packages required to build PHP5
apt-get build-dep php5
#Now what we need is to update compile options,
# so we need to edit debian/rules file:
# locate the line having "--with-gd=shared,/usr --enable-gd-native-ttf \"
# replace with "--with-gd=shared --enable-gd-native-ttf \"
# that's remove reference to /usr so that bundled library is used
# compile (drink some coffee, walk you dog, see the latest House episode)
# install the new php5-gd package
dpkg -i php5-gd_5.2.6.dfsg.1-3ubuntu4.2_i386.deb
# finally restart apache
Obviously, change the version number to match the version you're
actually compiling, and replace the flags with the ones you

How to execute home directory shell script file in php
Check the value of
return_var and display the value of
output - this will probably tell you that you have
the wrong permissions set on either /home, /home/scripts or on
ubuntu 10.04 command "# type php" returns nothing
PHP comes in several forms (Server APIs): CLI, CGI, Apache, Java
Servlet... Each of them has a separate binary.
php command is the CLI
version, intended only for running scripts on your
shell. Apache/LAMP does not use it.
Apache uses the Apache module version, which
comes in the
libapache-mod-php5 package and does
not have a visible command.
In other words, there is nothing wrong. You're just looking for a
different PHP SAPI.
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.
-r you can directly execute PHP code simply as
you would do inside a .php file when using the
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
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.
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
