php function What should I do if I get an error?

php error "Function name must be a string in xxxx"Solution

Problem description:

When writing php code, I mistakenly wrote the code $name = $_GET("name"); when running, it prompts "Function name must be a string"

Solution:

$ The _GET[""] method is written incorrectly. It is written as $_GET(""),

Reason:

is written as $_GET(""), PHP will first think that get() is a method, but there is an extra $ symbol in front of it, and PHP thinks it is a variable, and the variable name cannot be used as the name of the function, so "Function name must be a string" will be thrown.
