$find

Usage: $find(haystack,needle)

Category: text

Implemented: Picard 2.3

Description:

Returns the zero-based index of the first occurrence of needle in haystack, or an empty string if needle was not found. The comparisons are case-sensitive. If needle is blank, it will match the beginning of haystack and return “0”. The function does not support wildcards.

Note

Prior to Picard 2.3.2 $find returned “-1” if needle was not found.

Example:

The following statements will return the values indicated:

$find(abcdef,a)     ==>  "0"
$find(abcdef,c)     ==>  "2"
$find(abcdef,cd)    ==>  "2"
$find(abcdef,g)     ==>  ""
$find(abcdef,B)     ==>  ""
$find(,a)           ==>  ""
$find(abcdef,)      ==>  "1"
