I use these little doo-dads quite a bit. I just thought I'd share them and maybe save someone a little time. No biggy. :)
// returns true if $str begins with $sub
function beginsWith( $str, $sub ) {
return ( substr( $str, 0, strlen( $sub ) ) == $sub );
}
// return tru if $str ends with $sub
function endsWith( $str, $sub ) {
return ( substr( $str, strlen( $str ) - strlen( $sub ) ) == $sub );
}
// trims off x chars from the front of a string
// or the matching string in $off is trimmed off
function trimOffFront( $off, $str ) {
if( is_numeric( $off ) )
return substr( $str, $off );
else
return substr( $str, strlen( $off ) );
}
// trims off x chars from the end of a string
// or the matching string in $off is trimmed off
function trimOffEnd( $off, $str ) {
if( is_numeric( $off ) )
return substr( $str, 0, strlen( $str ) - $off );
else
return substr( $str, 0, strlen( $str ) - strlen( $off ) );
