note 84395 added to function.microtime

I wanted to find out whether echo would be quicker in small chunks or one large chunk to test the theory mentioned in the previous post. The following experiment shows that there is no significant performance difference, in terms of execution time elapsed, between the two methods of using echo. I ran two test cases, one with a string that is 100000 bytes long and another with a string length of 1000000. The source code follows below. <?php function echobig($string, $bufferSize = 8192) { $splitString = str_split($string, $bufferSize); foreach($splitString as $chunk) echo $chunk; } global $dat; $dat = ""; function testit() { global $dat; $data = ""; for( $a = 0; $a <= 1000000; $a += 1 ) $data .= "a"; $u1= microtime(true); echobig( $data ); $u2= microtime(true); echo $data; $u3= microtime(true); $diff = $u2 - $u1; $diff2= $u3 - $u2; $dat .= "$diff2 $diff $u2 $u1\r\n"; } $i = 0; while( $i < 5 ) { testit(); $i += 1; } global $dat; $fp = fopen( "../Data/results.txt", "w" ); fwrite( $fp, $dat ); fclose( $fp ); ?> You can run the above experiment yourself or you can look at my test data.
