Re: Include file

[John Nichel <john@xxxxxxxxxxxx>]

Because I'm bored, I decided to test the theory.

AMD 3200xp
1.5gb Memory
RHEL AS 3

I ran the test 20 times, and 18 of those times, double quotes were 
faster than single quotes.  Don't always trust what you read.  Not to 
mention the fact that the 'faster' of the two was 'faster' by an average 
of less than .003 seconds to include 1000 files.

<?php

function microtime_float() {
	list ( $usec, $sec ) = explode ( " ", microtime() );
	return ( ( float ) $usec + ( float ) $sec );
}

for ( $i = 0; $i < 1000; $i++ ) {
	$fp = fopen ( "file_" . $i . ".php", "w" );
	fwrite ( $fp, "<?php\n\n\n?>" );
	fclose ( $fp );
}

$single_start = microtime_float();
for ( $i = 0; $i < 1000; $i++ ) {
	include ( 'file_' . $i . '.php' );
}
$single_end = microtime_float();

$double_start = microtime_float();
for ( $i = 0; $i < 1000; $i++ ) {
	include ( "file_" . $i . ".php" );
}
$double_end = microtime_float();

$single = $single_end - $single_start;
$double = $double_end - $double_start;

echo ( "Single Quotes : " . $single . " seconds.<br />\n" );
echo ( "Double Quotes : " . $double . " seconds.<br /><br />\n" );

if ( $double > $single ) {
	$time = $double - $single;
	echo ( "Single Quotes are " . $time . " seconds faster than double 
quotes." );
} else {
	$time = $single - $double;
	echo ( "Double Quotes are " . $time . " seconds faster than single 
quotes." );
}

?>
