New Comment:
Here is a shorter version based off of xdecock's code which has been
working well. I see value in having this available when using PHP in
CLI mode.
-------------------------------------------
#include <php.h>
#include <SAPI.h>
#include <dlfcn.h>
#include <string.h>
static char *argv0 = NULL;
#define MAX_TITLE_LENGTH 128
void setproctitle(char *title)
{
char buffer[MAX_TITLE_LENGTH];
int tlen = strlen(title);
memset(buffer, 0x20, MAX_TITLE_LENGTH);
buffer[MAX_TITLE_LENGTH-1] = '\0';
if( tlen < (MAX_TITLE_LENGTH-1) )
memcpy(buffer, title, tlen);
if( argv0 )
snprintf(argv0, MAX_TITLE_LENGTH, "%s", buffer);
}
void set_proctitle_init()
{
sapi_module_struct *symbol = NULL;
symbol = (sapi_module_struct *)dlsym(NULL, "sapi_module");
if( symbol )
argv0 = symbol->executable_location;
}
PHP_FUNCTION(setproctitle)
{
char *title;
long tlen;
if(zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "s",&title,
&tlen) == FAILURE)
RETURN_FALSE;
setproctitle(title);
}

I've tried to make a port of the apache thing used for wikipedia to a
more generic one.
If it can be usefull for anyone (only tested it on cli, as i search the
way of doing this for cli primary)
Not sure how good is this method, at first seen, it works
proctitle.h & config.m4 are almost the same (except for MREQUEST_INIT &
MREQUEST_SHUTDOWN), but it is not usefull for CLI
the url for those files:
http://wikipedia.svn.sourceforge.net/viewvc/wikipedia/trunk/extensions/pecl-proctitle/php_proctitle.h?revision=9174&view=markup
#proctitle.c

Is there currently a way to do this in php 5? It doesn't appear that
the pecl module listed below is actually around any longer:
http://cvs.sourceforge.net/viewcvs.py/wikipedia/extensions/pecl-proctitl
e/
and a search for it turned up nothing. I'm just curious if this has
been implemented or is this possible now on linux systems?

It appears someone has implemented this:
http://cvs.sourceforge.net/viewcvs.py/wikipedia/extensions/pecl-proctitle/
I'm going to try and compile it now.

This would be a very nice feature. Using perl you can change $0
variable. PHP do lack this functionality.
---From perlvar doc-----
$0 Contains the name of the program being executed.
On some (read: not all) operating systems assigning to $0 modifies the
argument area that the "ps" program sees. On some platforms you may
have to use special "ps" options or a different "ps" to see the
changes.
Modifying the $0 is more useful as a way of indicating the current
program state than it is for hiding the program you're running.
(Mnemonic: same as sh and ksh.)
Note that there are platform specific limitations on the the maximum
length of $0. In the most extreme case it may be limited to the space
occupied by the original $0.
In some platforms there may be arbitrary amount of padding, for example
space characters, after the modified name as shown by "ps". In some
platforms this padding may extend all the way to the original length of
the argument area, no matter what you do (this is the case for example
with Linux 2.2).
Note for BSD users: setting $0 does not completely remove "perl" from
the ps(1) output. For example, setting $0 to "foobar" may result in
"perl: foobar (perl)" (whether both the "perl: " prefix and the "
(perl)" suffix are shown depends on your exact BSD variant and version).
This is an operating system feature, Perl cannot help it.
In multithreaded scripts Perl coordinates the threads so that any
thread may modify its copy of the $0 and the change becomes visible to
ps(1) (assuming the operating system plays along). Note that the the
view of $0 the other threads have will not change since they have their
own copies of it.
