The following path for cli version is concerned with passing arguments
to scripts. I found out that not all ways work correct and $PHP_SELF is not set
at all. The four example below explain the patch. All four execute:
echo "$PHP_SELF\n";
echo join($argv,',')."\n";
1) Execute a file using -f and pass 'a -b c' -> before patch scriptfile was
set to a -> didn't work
$ php -f /t/temp/arg.php a -b c
/t/temp/arg.php
/t/temp/arg.php,a,-b,c
2) Execute a file using without and pass 'a -b c' -> before patch
scriptfile was set to a -> didn't work
$ php /t/temp/arg.php a -b c
/t/temp/arg.php
/t/temp/arg.php,/t/temp/arg.php,a,-b,c
3) Execute code directly and pass 'a -b c' -> before patch scriptfile was
set to a -> didn't work
$ php -r 'echo "$PHP_SELF\n".join($argv,",")."\n";' a -b c
-
-,a,-b,c
4) Execute stdin and pass 'a -b c' -> before patch passing arguments wasn't
possible at all
$ echo '<?echo "$PHP_SELF\n".join($argv,",")."\n";?>' | php -- a -b c
-
-,a,-b,c
There was no need to change function ap_php_getopt as it does handle -- to
end interpreting arguments.
But i added PHP_SELF and set it to either the executed script or "-" for
stdin/run code. The
value for argv[0] seen by script is set to the same value to make argument
enumerating consistent.
An opportunity would be setting argv[0] of script to argv[0] of cli. This
way the user could get the
execution-path on some systems.
Any suggenstions? May i commit the change?
