A small follow-up:
After doing some reading, it turns out that PHP has a more efficient
manner of reading text files (which uses mem-mapping to avoid extra
string copying), called file_get_contents(). So here's a slightly
expanded version which uses that function (using fopen() and friends
would probably be optimal, though) and takes an array of JS files,
effectively concatenating the results into one script:
<?php
ob_start( 'ob_gzhandler' );
// optional: header( "Expires: Fri, 27 Aug 2010 12:12:12 GMT" );
foreach( array(
'jquery-1.1.3.1.yuimin.js',
'jquery.cycle.all.yuimin.js'
)
as $fn ) {
echo file_get_contents($fn);
echo ";\n"; // accommodate scripts which are missing a
trailing semicolon
}
ob_end_flush();
?>
Happy hacking!
