After upgrading to PHP v4.0.6 from v4.0.5 this problem seems to have started. When using yp_match() the documentation states:

"yp_match() returns the value associated with the passed key out of the specified map or FALSE"

However, FALSE is *NOT* returned if the key does not exist. Instead, I get the warning:

"Warning: no such key in map in [my script] on line [my line]"

As a quick fix, I surpress the error with @yp_match(). Has the function changed or is the documentation wrong?

My config is as follows:
./configure  
--with-apxs=/afs/rcf/apps/apache/sun4x_57/1.3.20/bin/apxs 
--with-config-file-path=/afs/rcf/apps/apache/sun4x_57/1.3.20/conf
--prefix=/afs/rcf/apps/apache/sun4x_57/1.3.20 
--with-pgsql=/afs/rcf/apps/pgsql 
--with-imap=/afs/rcf/admin/local 
--with-ldap=/afs/rcf/admin/local 
--with-xml 
--without-mysql 
--enable-track-vars 
--enable-magic-quotes 
--enable-yp 
--enable-debug 
--disable-short-tags

Changes were made between version 4.0.5 and 4.0.6 to display this warning.

However, the function still returns FALSE, and should work as before if warning is suppressed via @yp_match() or error_reporting()

R.

yp_match() returns the value correctly, but generates a warning on a "sucessful failure", meaning that a warning is generated when the match fails, and the return value is false (this is as of 4.2.3).

When there is no match, a warning should not be generated. This is the purpose of the call, to find or not find something.
