Hello there..

Doubling the quote is the standard way and it works from php in my
case:

$result = mssql_query("select 'it''s a giraffe!' ");

I don't use pear, you should check if Pear does some mangling with your
string before sending it off to SQL Server.

For future reference: PHP has very similar string represtentation as
Perl, double quoted strings are expanded for variables (f.x. "you are
number $i") and expressions inside {} (f.x. "my name is
{$userObject->somevariable['array index']}"), as well as
escape-sequences such as \n,\t etc. Single quoted strings are not
expanded, except for \'.

You should be able to double the single quote:

1> select 'It''s alright. Da doo du da doo du....'
2> go

 -------------------------------------
 It's alright. Da doo du da doo du....

That's the only standard way, afaik.  It works in tsql and sqsh.  If
it
doesn't work in PHP, it's a bug.  You could work around it with:

1> select 'It' + char(39) + 's alright'
2> go

 ------------
 It's alright

You can also alternate quoting characters (select "It's alright").  

Note these are SQL quoting rules, which are weird.  Other languages
have
their own.  I don't use PHP, so I don't know how strings are expressed,
but
for instance Perl wouldn't permit doubling up the quote; the
delimiting
character can't appear in the string without being escaped. 
(Fortunately
Perl is very flexible on the point, accepting as a delimiter single or
double quotes, or even any arbitrary character prefixed with "qq".)  

HTH.
