To John Galt:
remember that eval is a costly operation ( eval is evil )
some alternatives:
<?php
$score = array();
$start = microtime( true );
explode( ';', 'A;B;C;D' );
$score['explode'] = microtime(true) - $start;
$start = microtime(true);
unserialize('a:4:{i:0;s:1:"A";i:1;s:1:"B";i:2;s:1:"C";i:3;s:1:"D";}');
$score['unserialize'] = microtime(true) - $start;
$start = microtime(true);
eval('return array("A", "B", "C", "D");');
$score['eval'] = microtime(true) - $start;
print sprintf( "method %s is slowest\n", array_search( max( $score ), $score ));
?>
