Script speed analyse

01-12-2007, 04:54 PM

Hello to all,
I have the following script. This one read pictures in a directory and show them quickly.
The $files array is about 4000 rec. big. When the variable $filtre should select only 10 to 50 pictures it take to much time for the moment and I'm looking if
I can optimize this.
Question : it is possible with PHP to analyses the used time between some scripts lines?
Could be more difficult when I'm also using Javascript!

Thanks in advance for any help.
Otto

// Session variables
$files = $_SESSION['files'];
$filtre = $_GET['filtre'];

# Display speed
$peed = 250;

# Directory of pictures
$pict_path = "camera25/";

echo "
<script type='text/javascript'>
Animation=new Array();
bild=new Array();
var i=0;
";

# Selection (filtre)
$by = 1;
while ($by < count($files))
{
if (substr($files[$by],10,6) == $filtre)
{
echo "bild[$by]='$pict_path$files[$by]';\n";
}
$by++;
}

echo "
for(r=0;r < $by; r++)
{
Animation[r]=new Image(); Animation[r].src=bild[r];
}

function anzeigen()
{
if(i < $by){
document.images.dummy.src=Animation[i].src;
i++;
}
else
{
i=0;
}
setTimeout('anzeigen()',$peed);
}
</script>

<body onLoad='anzeigen();'>
<div align=left><img name='dummy'></div>";
?>

Hello!

You should see, that a PHP Script is running on the Server, Javascript
on the Client.
So, Javascript has nothing to do with the PHP Script time.

How long is a Script running?

<?PHP
$start = time();

// Your Script

$end = time();
$scripttime = $end - $start;
// taaataaaaa
?>

Maybe you can use additionally ob_start() .....etc
