hex2bin

Available since Exponential 6.0.13.

Summary

Returns false on invalid input; suppress PHP's E_WARNING for odd-length or non-hex strings so the template doesn't crash.

Description

PHP string function operators for Exponential templates.

Provides template access to PHP string functions documented at
https://www.php.net/manual/en/ref.strings.php that are NOT already
covered by existing Exponential template operators.

The piped input value maps to the primary string argument of each PHP
function. Additional template parameters map to the remaining PHP arguments
in left-to-right positional order.

The following operators are intentionally NOT implemented in this class
because they are already available as built-in Exponential template operators:
  chr, ord, trim, nl2br, rot13/str_rot13, crc32, md5, sha1, concat,
  indent, upcase/strtoupper, downcase/strtolower, count_chars (mb_strlen),
  count_words, break (nl2br), wrap/wordwrap, shorten, pad/str_pad,
  upfirst/ucfirst, upword/ucwords, simplify, wash/htmlspecialchars,
  append, prepend, merge, contains, compare, extract, extract_left,
  extract_right, begins_with, ends_with, implode, explode,
  repeat/str_repeat, reverse/strrev, insert, remove, replace, unique,
  array_sum.

Creative additions:
- ristring: str_replace(search, replace, subject) — case-sensitive replace
- rstring:  str_ireplace(search, replace, subject) — case-insensitive replace
