index, IndexCase
| Format: index ( string, substring [ , position ] ) |
| Format: IndexCase ( string, substring [ , position ] ) |
Purpose: Looks for a substring in a string. The string and substring parameter must be strings. The position parameter must be an integer. If position is not given, it defaults to 0.
The IndexCase() function works very similar but is not case sensitive.
Return Values: Looks for substring in string from the position denoted by position and returns the position where it starts. If the substring is not contained within the string, null is returned.
Example:
| resulting output: | |
<? index("Hello World","ello")> | 1 |
<? index("Hello World","xello")> | |
<? index("Hello World","ello", 5)> | |
<? index("Hello World","world")> | |
<? indexCase("Hello World","world")> | 6 |
