PHP Operators. Operators are used to perform operations on variables and values. PHP divides the operators in the following groups: Arithmetic operators; Assignment operators; Comparison operators; Increment/Decrement operators; Logical operators; String operators; Array operators; Conditional assignment operators

A full list of PHP operators follows in the section Operator Precedence. The section also explains operator precedence and associativity, which govern exactly how expressions containing several different operators are evaluated.

Jun 2, 2024 · It’s meaning is to say that what is on the right of the operator is a member of the object instantiated into the variable on the left side of the operator. Instantiated is the key term here. So -> is like the . in JAVA. $ages = ["Peter" => 32, "Quagmire" => 30, "Joe" => 34, 1 => 2]; . foreach ($ages as $name => $age) {

It's the "null coalescing operator", added in php 7.0. The definition of how it works is: It returns its first operand if it exists and is not NULL; otherwise it returns its second operand. So it's actually just isset() in a handy operator. Those two are equivalent 1: $foo = $bar ?? 'something'; $foo = isset($bar) ? $bar : 'something';

Jul 4, 2010 · When the left part is an object instance, you use ->. Otherwise, you use ::. This means that -> is mostly used to access instance members (though it can also be used to access static members, such usage is discouraged), while :: is usually used to access static members (though in a few special cases, it's used to access instance members).

Oct 18, 2021 · 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 value

Apr 5, 2025 · In PHP, operators are special symbols used to perform operations on variables and values. Operators help you perform a variety of tasks, such as mathematical calculations, string manipulations, logical comparisons, and more.

PHP uses a temporary variable for combined assign-operators (unlike JavaScript), therefore the left-hand-side (target) gets evaluated last. Input: $a += $b + $c; Meaning: $a = ($b + $c) + $a; …

Use the PHP AND operator (and, &&) to combine two boolean expressions and return true if both expressions evaluate to true; otherwise, it returns false. The logical AND operator is short-circuiting. Did you find this tutorial useful?

Searches for needle in haystack using loose comparison unless strict is set. The searched value. If needle is a string, the comparison is done in a case-sensitive manner. The array. If the third parameter strict is set to true then the in_array () function will also check the types of …
