.SH EXAMPLES
.TP 5
-php -r "echo 'Hello World';"
+php \-r 'echo "Hello World\\n";'
This command simply writes the text "Hello World" to stabdard out.
.TP
-php -d html_errors=1 -i | php -R 'echo strip_tags($argn)."\\n";'
+php \-r 'print_r(gd_info());'
+This shows the configuration of your gd extension. You can use this
+to easily check which imag formats you can use. If you have any
+dynamic modules you may want to use the same ini file that php uses
+when executed from your webserver. There are more extensions which
+have such a function. For dba use php \-r 'print_r(dba_handlers(1));'
+.TP
+php \-d html_errors=1 \-i | php \-R 'echo strip_tags($argn)."\\n";'
This example uses PHP first to generate a HTML output. This is
meant to be replaced with any tool that displays HTML (for instance
you could use 'cat file.html'). The second php command now strips off
the HTML tags line by line and outputs the result.
.TP
-php -E 'echo "Lines: $argi\\n";'
+php \-E 'echo "Lines: $argi\\n";'
This command shows the number of lines being input.
.TP
-php -R '@$l+=count(file($argn));' -E ' echo "Lines: $l\\n";'
+php \-R '$l+=count(file($argn));' \-E'echo "Lines:$l\\n";'
This commands 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.
+.TP
+php \-R 'echo $argn; fgets(STDIN);'
+Since you have access to STDIN from within \-B \-R and \-F 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
