Ob start un end

[cucumber]

Es taisu es ierakstu bildes tadus no datu bazes, ar sho metodi, bet pec ta man pazud php mainigie. Kur var but vaina?

$a = "abc";

ob_start(); // start a new output buffer
  imagejpeg($resize,"",$quality);
  $ImageData = addslashes(ob_get_contents());
ob_end_clean();

echo $a; //nekas nav

[Joyride]

ob_end_clean() funkcija atgriez output bufera saturu un "izsledz" output buffering.

[cucumber]

Izdorot ta $ImageData = addslashes(ob_end_clean()); kluda paliek.

ko tu vispār mēģini izdarīt ?

[cucumber]

Ir bilde uz servera, kuru padotu funkcijai, kas apstrada to (dabu augstumu, platumu), tad to bildi meginu samazinat un ierakstit ieksh db, nesaglabajot uz cieta diska.

 

 $im_data = getimagesize($infile);

$im=imagecreatefromjpeg($infile);	  
$resize=imagecreatetruecolor($w,$h);
imagecopyresampled($resize,$im,0,0,0,0,$w,$h,imagesx($im),imagesy($im));

ob_start(); // start a new output buffer
  imagejpeg($resize,"",$quality);
  $ImageData = addslashes(ob_get_contents());
ob_end_clean();

  //query izbilde, tikai tas nenotiek, jo pazud dati no ta
echo "aaaa"; //ari vairs neizpildisies	

imagedestroy($im);	
imagedestroy($resize);

[Delfins]

ob_start();

image_jpeg();
$data = ob_get_contents();
$data = do_smth($data);

ob_end_clean();

 

PS: vismaz man viss strādā
