This simple function should do the trick. It does no verification on the string format, though.

function reformat_time_string($timestr) {
    $vals = sscanf($timestr, "%dh %dm");
    $total_min = ($vals[0] * 60) + $vals[1];
    return "$total_min mins";
}

$timestr = "2h 15m";
echo reformat_time_string($timestr); /* echoes '135 mins' */

$str="1h 38 min";
$s = explode(" ",$str);
if ( strpos ( $s[0] ,"h" ) !==FALSE) {
    $hr=str_replace("h","",$s[0]);
    print ($hr*60) + $s[1]."\n";
}

$pattern = '!(\d+)\s*h\s*(\d+)\s*min!';
foreach( array('1h 38 min', '2h 20 min') as $input) {
  echo preg_replace_callback($pattern, function($x) { return ($x[1]*60+$x[2]).' minutes'; }, $input), "\n";
}

prints

98 minutes
140 minutes

for php versions prior to 5.3 you'd have to use

function foo($x) {
  return ($x[1]*60+$x[2]).' minutes';
}
$pattern = '!(\d+)\s*h\s*(\d+)\s*min!';
foreach( array('1h 38 min', '2h 20 min') as $input) {
  echo preg_replace_callback($pattern, 'foo', $input), "\n";
}
