XtScript Function: strrpos and strripos

Find the last occurrence of a case-sensitive, or case-insensitive substring and return the position.

XtScript strrpos and strripos is XtScript function that will search and return the position of the last occurrence of a matched substring.

The difference between strrpos and strripos is that strrpos will search the substring as CASE-SENSITIVE, while strripos as CASE-INSENSITIVE.

If you want the function to search and return the position of the first occurrence of a substring, you can use XtScript strpos and stripos function instead.

XtScript strrpos and strripos function basic syntax:

<!--parser:xtscript-->
	# Find the last occurrence of a case-sensitive substring and return the position
	call strrpos $haystack=...; $needle=...; $offset=...

	# Find the last occurrence of a case-insensitive substring and return the position
	call strripos $haystack=...; $needle=...; $offset=...
<!--/parser:xtscript-->

Available arguments in XtScript strrpos and strripos function:

XtScript strrpos and strripos function arguments
ArgumentValueMandatoryExplanation
$haystackstringRequiredSpecify the main string where the substring will be searched in.
$needlestringRequiredSpecify the substring that searched for.
$offsetnumberOptionalSpecify the index of a character the search will be started from. Negative value will make the function work started from the number from the end of string, making it has backward behaviour.

	var $fname = Jordan
	var $name = Michael

	print Names: $string <br/><br/>

	print "$fname" family name found on position: <b>
	call strrpos $haystack=$string; $needle=$fname
	print </b> <br/><br/>

	print "$name" found on position: <b>
	call strrpos $haystack=$string; $needle=$name
	print </b>
<!--/parser:xtscript-->
- Result:
Names: Adam Jordan | Michael Jordan | Angela Jordan | michael Heissenberg

"Jordan" family name found on position: 38

"Michael" found on position: 14

Remember that index on programming like Javascript, PHP, and also XtScript is always started at 0.

Search and return the position of the last occurrence of a case-insensitive substring using XtScript strripos function

- Code: 
<!--parser:xtscript-->
	var $string = Go Goes Going GOal
	var $srch = go

	print String: $string <br/><br/>

	print "$srch" found at position: <b>
	call strripos $haystack=$string; $needle=$srch;
	print </b> <br/><br/>

	print With \$offset=-5, "$srch" found at position: <b>
	call strripos $haystack=$string; $needle=$srch; $offset=-5
	print </b>
<!--/parser:xtscript-->
- Result:
String: Go Goes Going GOal

"go" found at position: 14

With $offset=-5, "go" found at position: 8
