Hello,
I am trying to get ob_start to work the way I expect but I am running
into some problems.
Take the following example code:
/* Start of code snippet */
function ob_spit_content_length ($buffer) {
$len=strlen($buffer);
if($len>0) Header( "Content-Length: $len" );
return $buffer;
}
if( !function_exists("ob_end_clean_all") ) {
function ob_end_clean_all () {
while ( ob_get_level() ) {
ob_end_clean();
}
}
}
ob_start("ob_spit_content_length");
ob_start("ob_gzhandler");
print "There is lots of stuff right here!";
ob_end_clean_all();
/* End of code snippet */
I am running PHP 4.3.0 and my desire is to compress all output (if
browser supports) and also send the content-length header rather than
sending chunked so that my output looks as close to static as possible.
My understanding is that ob_start can be nested and since I registered
"ob_spit_content_length" first and then "ob_gzhandler" second that
"ob_gzhandler" will run first and therefor $buffer being send to
"ob_spit_content_length" with either be clear text "browser does not
support compression" or the compress version of the page. Either way
strlen will get me my length.
Well I get very strang effects and as soon as I comment out my 2 ob_start
calls every think works fine. Often times op_spit_content_length will
say 0 bytes even though I *KNOW* output was sent.
Am I missing something here? Did I layer things wrong? Any suggestions
would be much appreciated.
Thanks,
Serge.
