Index function returns the location of the first occurrence of a substring within a string

#  $start = index($string, $look_for); #  If you intend to search a string for multiple occurrences of the look-for substring, you can use the optional start position: #  $start = index($string, $look_for, $start_position); #!/usr/bin/perl -w # Look for a substring with index. $look_for = "then"; $start = index("First A, then B", $look_for); print "$look_for starts at $start\n";
