Difference between == and === operators in PHP

In PHP, the '==' operator is used for comparison between two values, but it does not check the data type of the values. On the other hand, the '===' operator not only compares the values but also ensures that the data types of the values are the same. This means that '===' is a strict comparison operator.

When using '==' operator, PHP will attempt to convert the values to the same data type before making the comparison. However, with '===', the data types must be the same in order for the comparison to return true.

It is recommended to use '===' when comparing values in PHP to ensure accurate and reliable results, especially when dealing with different data types.
