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?
