php - codeigniter and fpdf code blockin during pdf output -

-

i have big problem fpdf

in page have lot of code , @ end create pdf file sample:

require('fpdf.php'); $pdf = new fpdf(); $pdf->addpage(); $pdf->setfont('arial','b',16); $pdf->cell(40,10,'hello world!'); ob_end_clean(); $pdf->output();

the result creatioin of pdf make , other code no !

first code of sample is:

require('fpdf.php'); $pdf = new fpdf(); $pdf->addpage(); $pdf->setfont('arial','b',16); $pdf->cell(40,10,'hello world!'); //ob_end_clean(); $pdf->output();

like code before execute without problem not pdf , receive on browser:

fpdf error: data has been output, can't send pdf file

can me ? im newbie fpdf libraries

that because php code has already outputted data browser. check php not write data browser yet ( except headers ) before calling $pdf->output(), avoiding sending unknown data has pdf binary data appended @ end.

the ob_end_clean() function call ensure script clean previous output php script have made.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
