PHP: Assignment
Assignment Operators. The basic assignment operator is "=". Your first inclination might be to think of this as "equal to". Don't. It really means that the left operand gets set to the value of the expression on the right (that is, "gets set to").
Reference assignment operator in PHP, =&
I agree with Artefacto, this answer is wrong and actively misleading. There is no such thing in PHP as "accessing a variable by reference", and assignment by reference is not the same operation as a normal assignment. I realise it was a long time ago that you wrote this answer, but can see that you're still active, so please can you have a look at this answer with more experienced eyes, and ...
PHP Operators
PHP Assignment Operators. The PHP assignment operators are used with numeric values to write a value to a variable. The basic assignment operator in PHP is "=". It means that the left operand gets set to the value of the assignment expression on the right.
PHP Assignment Operators
Use PHP assignment operator ( =) to assign a value to a variable. The assignment expression returns the value assigned. Use arithmetic assignment operators to carry arithmetic operations and assign at the same time. Use concatenation assignment operator ( .= )to concatenate strings and assign the result to a variable in a single statement.

PHP: Operators
An operator is something that takes one or more values (or expressions, in programming jargon) and yields another value (so that the construction itself becomes an expression). Operators can be grouped according to the number of values they take. Unary operators take only one value, for example ! (the logical not operator) or ++ (the increment ...
PHP: Comparison
If both operands are numeric strings, or one operand is a number and the other one is a numeric string, then the comparison is done numerically.These rules also apply to the switch statement. The type conversion does not take place when the comparison is === or !== as this involves comparing the type as well as the value.
PHP Operators
An operator takes one or more values, known as operands, and performs a specific operation on them. For example, the + operator adds two numbers and returns the sum of them. PHP supports many kinds of operators: Arithmetic Operators. Assignment Operators. Bitwise Operators. Comparison Operators.
PHP assignment operators
The value of an assignment expression is the final value assigned to the variable. In addition to the regular assignment operator "=", several other assignment operators are composites of an operator followed by an equal sign. Interestingly all five arithmetic operators have corresponding assignment operators, Here is the list. +=-= *= /= %=
Difference between the (=), (==), and (===) operators in PHP
In PHP, the '=' operator is used for assignment, while the '==' operator is used for loose equality comparison, meaning it checks if two values are equal without considering their data types. On the other hand, the '===' operator is used for strict equality comparison, meaning it checks if two values are equal and of the same data type.
PHP
Assignment Operators. The basic assignment operator is =, which takes the right-hand operand and assigns it to the variable that is the left-hand operand. PHP also has a number of additional assignment operators that are shortcuts for longer expressions. Arithmetic Assignment Operators. There is an assignment operator for each arithmetic ...
PHP Comparison Operators
A comparison operator allows you to compare two values and returns true if the comparison is truthful and false otherwise. The following table illustrates the comparison operators in PHP: Return true if both operands are equal; otherwise, it returns false. Return true if both operands are equal; otherwise, it returns false.
PHP Operators
Operators are symbols that instruct the PHP processor to carry out specific actions. For example, the addition (+) symbol instructs PHP to add two variables or values, whereas the greater-than (>) symbol instructs PHP to compare two values.PHP operators are grouped as follows: Arithmetic operators; Assignment operators; Comparison operators; Increment/Decrement operators
How do the PHP equality (== double equals) and identity (=== triple
PHP Double Equals ==: In most programming languages, the comparison operator (==) checks, on the one hand, the data type and on the other hand the content of the variable for equality. The standard comparison operator (==) in PHP behaves differently. This tries to convert both variables into the same data type before the comparison and only ...
How do the PHP equality (== double equals) and identity (=== triple
This should always be kept in mind that the present equality operator == is different from the assignment operator =. The assignment operator changes and assigns the variable on the left to have a new value as the variable on right, while the equal operator == tests for equality and returns true or false as per the comparison results. Example:
PHP: Operator Precedence
Operators of equal precedence that are non-associative cannot be used next to each other, for example 1 < 2 > 1 is illegal in PHP. The expression 1 <= 1 == 1 on the other hand is legal, because the == operator has a lower precedence than the <= operator. Associativity is only meaningful for binary (and ternary) operators.

PHP: Variable functions
Variable functions. ¶. PHP supports the concept of variable functions. This means that if a variable name has parentheses appended to it, PHP will look for a function with the same name as whatever the variable evaluates to, and will attempt to execute it. Among other things, this can be used to implement callbacks, function tables, and so forth.

PHP Null Coalescing Operator
Summary: in this tutorial, you'll learn about the PHP Null coalescing operator to assign a value to a variable if the variable doesn't exist or null.. Introduction to the PHP null coalescing operator. When working with forms, you often need to check if a variable exists in the $_GET or $_POST by using the ternary operator in conjunction with the isset() construct.
PHP: Array
Note that + will not renumber numeric array keys. If you have two numeric arrays, and their indices overlap, + will use the first array's values for each numeric key, adding the 2nd array's values only where the first doesn't already have a value for that index.
