money_format() is deprecated starting with PHP 7.4. Use NumberFormatter Class instead.
I recently switched to an new machine, so I installed my local dev environment again. Brew provided 7.4, so I ran into a deprecation Error in an older poject.
The solution is fairly simple:
Rewrite the money_format function
setlocale( LC_MONETARY, 'de_DE.UTF-8' );
$amount = money_format( '%!n €', 2499 );
return $amount;
// 2.499,00 €to the NumberFormatter Class
$amount = new \NumberFormatter( 'de_DE', \NumberFormatter::CURRENCY );
return $amount->format( 2499 );
// 2.499,00 €Additionally I needed to maintain the amount's display without decimals so I had to rewrite
setlocale( LC_MONETARY, 'de_DE.UTF-8' );
$amount = money_format( '%!n €', 2499 );
return preg_replace( '/[,]00/', '', strval( $amount ) );
// 2.499 €to
$amount = new \NumberFormatter( 'de_DE', \NumberFormatter::CURRENCY );
$amount->setAttribute( \NumberFormatter::MAX_FRACTION_DIGITS, 0 ) ;
return $amount->format(2499);
// 2.499 €
