52.1k

These operators are used to compare two elements and return a boolean result. The comparison operators in PHP, along with their syntax and operations, are listed below. Example: The comparison operator in PHP is demonstrated in this example.

To perform comparisons, comparison operators are needed. Strings are combined using concatenation operators. AND, OR, and NOT are logical operators that are utilised to conduct logical operations. AND, OR, XOR, and NOT are examples of Boolean Operators, which can have one of two values: true or false.

PHP supports the common logical operators and, or, not, and xor. Logical operators convert their operands to boolean values before comparing them.

Equal to, not equal to, greater than, greater than or equal to, less than, and less than or equal to are the six main comparison operators. These operators are expressed in different ways in different programming languages, but their meanings are the same.

Tilde, dot, wedge, horseshoe, and triple bar are the five logical operator symbols.
