Final answer:
The PHP operator to check if the expression on the left is greater than or equal to the expression on the right is the >= operator.
Step-by-step explanation:
The PHP operator to check if the expression on the left is greater than or equal to the expression on the right is the >= operator.
In PHP, the 'greater than or equal to' operator denoted by '>=' evaluates if the left expression is greater or equal to the right expression.
The greater than or equal to operator in PHP is denoted by '>='. This operator returns a TRUE value if the expression on its left side is greater than or equal to the expression on its right side. For instance, in the comparison 5 >= 3, since 5 is indeed greater than 3, this expression would evaluate to TRUE.
