sprintf	sprintf( format, ...args ) — format is operatorValue, args are template params Uses vsprintf internally to accept a flat list of positional parameters.
str_contains	str_contains( haystack, needle ) — PHP 8.0+; fallback for older PHP
str_ends_with	str_ends_with( haystack, needle ) — PHP 8.0+; fallback for older PHP
str_getcsv	str_getcsv( string [, separator [, enclosure [, escape]]] ) PHP 8.4+ deprecates non-empty $escape; pass '' to opt-in to the RFC 4180-compliant behaviour and silence the deprecation notice.
