RE: [PHP] Client side fatal PHP error

Well, what you have said here isn't that clear, however consider the following revised code: $teststr = strtoupper(substr($xmbrcode,11,1)); if(($teststr != "B") && ($teststr != "P") && ($teststr != "H") && ($teststr != "O")){ do.. } What you are doing is executing the substr and strtoupper many times, which, on a slow connection which may have backlog (thus slower time for the html stream buffer to be delivered), it could timeout. More detail on a: the error, and b: the code *in context* would help.
