If speed is of any concern there are a few immediate things you can do 
to optimize.

1) quotes -- use single unless the string truly needs evaluation.  This 
is an extra step for php that is largely not needed. Especially inside 
loops.
ex: echo time2sec('1:36') . "\n";
ex: if( $char == ':' ) {

2) echo -- use commas not periods, when there is no need to concatenate.
ex: echo time2sec('1:36'), "\n";


HTH,
