In PHP, when we are going to declare a array directly, we have the => operator.
I know that in PHP we have -> , which is object separator , but I needed to give the name to => and could not explain.
What's his name?
=> ) according to the manual is used to assign a value to a specific key in the array definition and also to separate a key from a value in a foreach, as quoted by bigown .
For arrays, assigning a value to a named key is performed using the "= >" operator . The precedence of this operator is the same as the other assignment operators.

On the precedence page you can see this line, note the last element of the second column.
Associativity |Operators |Additional Information
right | = += -= *= **= /= .= %= &= |= ^= <<= >>= => |assignment
As for the name of the symbol => in the PHP documentation there seems to be no specific name, the closest to the formal would be T_DOUBLE_ARROW (as pointed out in the comments), which appears in syntax errors.
Informally it is known as fat comma , term that probably came from Perl language PHP inherited some features .
Not an operator, contrary to popular belief and error in Wikipedia, at least for PHP. The language has these operators . It's just a language-building element that separates the key from associative arrays .
