Example
$text = 'This is a test'; println( strlen($text) ); // 14 // the string is reduced to 't', so it prints 1 println( "1: " . SubstrCount($text, 't', 13, 1) ); // the string is reduced to 'This is a test', so it prints 2 println( "2: " . SubstrCount($text, 'is') ); // the string is reduced to 's is a test', so it prints 1 println( "1: " . SubstrCount($text, 'is', 3) ); // the text is reduced to 's i', so it prints 0 println( "O: " . SubstrCount($text, 'is', 3, 3) ); // the text is reduced to '', because 5+10 > 14, so it prints 0 println( "O: " . SubstrCount($text, 'is', 5, 10) ); // prints only 1, because it doesn't count overlapped substrings $text2 = 'gcdgcdgcd'; println( "1: " . SubstrCount($text2, 'gcdgcd') );
