Hi there,
I'm not trying to change this list into a PHP forum, but I have a
question
regarding speed optimization in PHP, especially about data accumulation
into strings...
I need to accumulate a large number of pixel values into a string before
passing the string back to my Rev cgi script.
Below is the best I managed to code, which is still painfully slow when
compared to what can be achieved with Rev...
Question : is there a way to speed up things ?
In javascript, it is possible to accumulate data into an array, and then
change the
array into a string, which is much much faster than simply accumulating
data in
the string... Is anything similar possible with PHP ?
$s0 = "" ;
$s = "" ;
for($y = 0; $y < $h; $y++) {
$s0 = "" ;
for($x = 0; $x < $w; $x++) {
$s0 .= $myValue1 . " " . $myValue1 . " " . $myValue1 . "\t" ;
}
$s .= $s0 . "\n" ;
}
Thanks,
JB
