Should I use == or === PHP?

The equality == does not assign values, but compares them without checking their data types. The triple equals sign operator === won't do assignment, but will check for equality of values and the data type.

Can you use == for arrays?

On the other hand, to check if two arrays are equal in terms of their contents, Java provides the Arrays. equals static method. This method will iterate through the arrays, per position in parallel, and apply the == operator, for every pair of elements.

How do you compare two elements in an array list?

The ArrayList. equals() is the method used for comparing two Array List. It compares the Array lists as, both Array lists should have the same size, and all corresponding pairs of elements in the two Array lists are equal.

Which is faster == or === PHP?

In conclusion === is faster because don't converts the data type to see if two variables have same value, but when you need to see if two variables have same value you will use == if doesen't mather what type are variables, or === if is important also the type of variables.

Can arrays be compared with ==?
