Where di you hear that output buffers are expensive? I have found the
following:
<?php
ob_start();
for( $i = 0; $i < 10000000; $i++ )
{
echo 'blaaaaaaaaaaaaaaaaaaaaaaaaaah';
}
$foo = ob_get_contents();
ob_end_clean();
?>
To consistently be faster than the following:
<?php
for( $i = 0; $i < 10000000; $i++ )
{
$foo .= 'blaaaaaaaaaaaaaaaaaaaaaaaaaah';
}
?>
However, if I do the following:
<?php
for( $i = 0; $i < 10000000; $i++ )
{
ob_start();
echo 'blaaaaaaaaaaaaaaaaaaaaaaaaaah';
$foo .= ob_get_contents();
ob_end_clean();
}
?>
The run-time is approximately 3 times slower... not exactly expensive
considering it incorporates the concatenation as well as the output
buffering.
Cheers,
Rob.
