Can you provide a _self-contained_ sample script which reproduces the
problem.
BTW: $X = 1.22; is not bad syntax. It's just the way you represent
decimal values in PHP, no matter what the current locale is.

This is the problem of syntax checking and locale settings.
This script print a warning:
setlocale(LC_ALL, "en_US"); // US have a decimal pointer
$X = 1,22; // !!! bad syntax
This script doesn't print a warning:
setlocale(LC_ALL, "cs_CZ"); // CZ have a decimal comma
$X = 1.22; // !!! also bad syntax
The error caused by incorrect parsing of a float number is propagated
into the next script lines and cause a false alerts in a many
situations. When the variable is parsed as a string

Sometimes (1-10 times a day) appears a fatal bug
in my php code. Sometime this sprintf expression returns me string like
'0.05-0%':
<?echo $rs["pol_sazbadph"]."-".sprintf("%1.0f",$rs["pol_sazbadph"] *
100)."%"?>
This bug appears to me on two different servers:
1) Athlon based 2.4.12-k6 kernel - Apache/1.3.22 - php 4.1.0 RC3
'./configure' '--prefix=/usr' '--with-apxs=/usr/bin/apxs'
'--with-config-file-path=/ etc/php4/apache'
'--with-ibm-db2=/home/db2inst1/sqllib'
2) Pentium II based - 2.2.19pre17 kernel - Apache/1.3.9 -
php 4.0.3pl1
'./configure' '--prefix=/usr' '--with-apxs=/usr/bin/apxs'
'--with-regex=system' '--with- config-file-path=/etc/php4/apache'
'--with-db2' '--with-zlib' '--without-pgsql' '-- disable-static'
'--with-layout=GNU' '--with-zlib-dir=/usr' '--with-mysql=shared,/usr'
'-- with-ibm-db2=/home/db2inst1/sqllib'
The bug appears after we have compiled php against db2 libraries. I've
found another bug in sprintf with the same frequency of appearance in
bugs database. There is something bad in sprintf in some cases, but
what?
