The meaning of = in PHP

In PHP, the = operator is used for assignment operations. The value is assigned to the variable on the left. The assignment operation is a basic operation in PHP that can be used to create and modify variable values.

Assignment operation

The syntax of the assignment operation is as follows:

$variable = value;

Among them:

• $variable is the name of the variable to be assigned.
• value is the value to be assigned to the variable.

When the code executes, the value will be assigned to the $variable, and $variable will contain the value.

Example

The following example creates and assigns a variable:

$name = "John Doe";

After executing this code, the $name variable will contain String "John Doe".

Note

In PHP, the = operator cannot be used to compare two values. To compare two values, use comparison operators (such as ==, !=, ).

For example:

if ($a == $b) {
    // 两个值相等
} else {
    // 两个值不相等
}
