Does PHP have logical operators?
The PHP logical operators are used to combine conditional statements.
What are == and === operators in PHP?
The operator == casts between two different types if they are different, while the === operator performs a ‘typesafe comparison’. That means that it will only return true if both operands have the same type and the same value.
What is logical operators PHP?
In PHP, the logical operator xor stands for exclusive or. It takes two different boolean values or expressions as its operands and returns a single boolean value. xor evaluates to TRUE only if either its left operand or its right operand evaluate to TRUE , but not both.
What are the 5 PHP operators?

Is equal to operator in PHP?
The comparison operator called Equal Operator is the double equal sign “==”. This operator accepts two inputs to compare and returns true value if both of the values are same (It compares only value of variable, not data types) and return a false value if both of the values are not same.
What’s the difference between == and === PHP?
Introduction: Two of the many comparison operators used by PHP are ‘==’ (i.e. equal) and ‘===’ (i.e. identical). The difference between the two is that ‘==’ should be used to check if the values of the two operands are equal or not. On the other hand, ‘===’ checks the values as well as the type of operands.
Why are there so many logical operators in PHP?
PHP has many logical operators which make it easy to use. The PHP compiler helps in compiling these operators fast. The logical operators help in performing logical operations. These can be arithmetic operations, logical operations, string operations or array operations.
When to use the not operator in PHP?
The NOT operator is used when it is required to check if a particular variable is not true. Which means we can use NOT when we have to check if any condition is not true. In this example, you can see that we are checking if the variable is not 90. The variable x is 100 and which is clearly satisfying the NOT condition.
Do you know the Boolean operators in PHP?
Note that PHP’s boolean operators *always* return a boolean value… as opposed to other languages that return the value of the last evaluated expression. For example: $a = 0 || ‘avacado’; print “A: $a\ “; will print: A: 1 in PHP — as opposed to printing “A: avacado” as it would in a language like Perl or JavaScript.
When to use parenthesys and and in PHP?
But a more acurate one would be same goes for “&&” and “AND”. If you find it hard to remember operators precedence you can always use parenthesys – ” (” and “)”. And even if you get to learn it remember that being a good programmer is not showing you can do code with fewer words.
