php operator precedence

Operator Precedence is an important point of knowledge that a programmer must understand and hold, let's take a look at the PHP operator precedence article. Today in Lao Wang's technical manual saw a problem: The code is as follows

The two priorities are the same, and the comparison (comparision) and Assignment (Assignment) operations are slightly different. The comparison operator has a, =, and so on, the assignment operator has =, + =, *=, and so on. The comparison

The operator precedence specifies how tightly the two expressions are bound. For example, the result of the expression 1 + 5 * 3 is that it is because multiplication sign ("*") has a higher priority than the plus sign ("+"). You can use

Today in Lao Wang's technical handbook see a problem: The code is as follows Copy Code What is the output? This question may seem simple at first glance, but it is not easy to scrutinize it, If the Boolean

The operator precedence specifies how tightly the two expressions are bound. For example, the result of the expression 1 + 5 * 3 is that It is because multiplication sign ("*") has a higher priority than the plus sign ("+"). You can use

When we talked about the PHP logical operators, we mentioned the precedence of the PHP operators, the so-called operator precedence, which is the calculation of which operation Mr. Foo in the expression, which is calculated as if the result of the

Arithmetic operators Operator name Result $a + $b addition $a and $b and $a-the difference between $b subtraction $a and $b $a * $b multiplication $a and the product of $b $a/$b division $a divided by the quotient of the $b $a% $b modulo $a divided
