There is an extension for operator overloading in PHP 7, [pecl-php-operator](https://github.com/php/pecl-php-operator), but it has been broken since PHP 7.4. This extension is a rewrite of that extension, but for PHP 8. Regular Operators ----------------- [](#regular-operators) These operators are the ones that make the most sense to overload. They are assignment, unary, binary, and comparison operators. ### [Arithmetic Operators](https://www.php.net/manual/en/language.operators.arithmetic.php) [](#arithmetic-operators) Operator NameOperatorImplementedFunction CallIdentity`+$a`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)Negation`-$a`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)Addition`$a + $b`Yes`$a::__add($b)`Subtraction`$a - $b`Yes`$a::__sub($b)`Multiplication`$a * $b`Yes`$a::__mul($b)`Division`$a / $b`Yes`$a::__div($b)`Modulo`$a % $b`Yes`$a::__mod($b)`Exponent`$a ** $b`Yes`$a::__pow($b)`### [Assignment Operators](https://www.php.net/manual/en/language.operators.assignment.php) [](#assignment-operators) Operator NameOperatorImplementedFunction CallAssignment`$a = $b`Yes`$a::__assign($b)`### [Bitwise Operators](https://www.php.net/manual/en/language.operators.bitwise.php) [](#bitwise-operators) Operator NameOperator UseImplementedFunction CallAnd`$a & $b`Yes`$a::__bw_and($b)`Or`$a | $b`Yes`$a::__bw_or($b)`Xor`$a ^ $b`Yes`$a::__bw_xor($b)`Not`~$a`Yes`$a::__bw_not($b)`Shift left`$a > $b`Yes`$a::__sr($b)`### [Comparison Operators](https://www.php.net/manual/en/language.operators.comparison.php) [](#comparison-operators) Operator NameOperator UseImplementedFunction CallEqual`$a == $b`Yes`$a::__is_equal($b)`Identical`$a === $b`Yes`$a::__is_identical($b)`Not equal`$a != $b`Yes`$a::__is_not_equal($b)`Not equal`$a $b`Yes`$a::__is_not_equal($b)`Not identical`$a !== $b`Yes`$a::__is_not_identical($b)`Less than`$a < $b`Yes`$a::__is_smaller($b)`Greater than`$a > $b`Yes[2](#user-content-fn-4-d6399168c96e5415e25a1281eb032679)`$a::__is_greater($b)`Less than or equal`$a = $b`Yes[2](#user-content-fn-4-d6399168c96e5415e25a1281eb032679)`$a::__is_greater_or_equal($b)`Spaceship`$a $b`Yes`$a::__spaceship($b)`Ternary`$a ?: $b`NoNull coalescing`$a ?? $b`No[3](#user-content-fn-3-d6399168c96e5415e25a1281eb032679)### [Incrementing/Decrementing Operators](https://www.php.net/manual/en/language.operators.increment.php) [](#incrementingdecrementing-operators) Operator NameOperator UseImplementedFunction CallPre-increment`++$a`Yes`$a::__pre_inc`Post-increment`$a++`Yes`$a::__post_inc`Pre-decrement`--$a`Yes`$a::__pre_dec`Post-decrement`$a--`Yes`$a::__post_dec`### [Logical Operators](https://www.php.net/manual/en/language.operators.logical.php) [](#logical-operators) Operator NameOperator UseImplementedFunction CallAnd`$a and $b`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)Or`$a or $b`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)Xor`$a xor $b`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)Not`$a ! $b`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)And`$a && $b`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)Or`$a || $b`Maybe[1](#user-content-fn-1-d6399168c96e5415e25a1281eb032679)### [String Operators](https://www.php.net/manual/en/language.operators.string.php) [](#string-operators) Operator NameOperator UseImplementedFunction CallConcatenation`$a . $b`Yes`$a::__concat($b)`Combination Assignment Operators -------------------------------- [](#combination-assignment-operators) There are a few assignment operators that are overloaded. These are an operator and an assignment operator combined[4](#user-content-fn-2-d6399168c96e5415e25a1281eb032679). For example, `+=` is an addition assignment operator.

Many of them don't make sense to overload. The full opcode list can be found in the `php-src` repo [here](https://github.com/php/php-src/blob/master/Zend/zend_vm_opcodes.h#L86). Footnotes --------- 1. This might be the same as other opcodes, or maybe there is no opcode for it, but I'm not sure. I haven't tested it yet.
