PHP Operator (3) 'Assignment Operator' Example Explanation
What is php assignment operator?
The most basic form of the assignment operator is "=". The "=" here does not mean "equal", but means assignment. Its function is simply to assign a value to a variable. For example, $A=10 means assigning 10 to $A, so the value of $A is 10.

Of course this Just the most basic assignment operator. In addition to the most basic "=" assignment operator, we also have other forms of assignment operators, which we call compound assignment operators, as shown in the following table
| Operator | Explanation | Example | is equivalent to | Meaning |
| = | Assignment | $a=b | $a=b | Assign the value on the right to the left |
| += | Add | $a+=b | $a=$a+b | Add the value on the right to the left |
| -= | minus | $a-=b | $a=$a-b | Subtract the value on the right to the left |
| *= | Multiply | $a*=b | $a=$a*b | Multiply the value on the right by the value on the left divided by |
| /= | $a/=b | $a=$a/b | Divide the value on the right by the value on the left | |
| .= | Connection characters | $a.=b | #$a=$a.b | Add the characters on the right to the left |
| % | Get the remainder | $a%=b | $a=$a+%b | Take the remainder of the value on the left to the right |

The code is as follows
<?php $a=20; echo $a."<br/>"; // 输出 20 $y=20; $y += 80; echo $y."<br/>"; // 输出 100 $z=50; $z -= 25; echo $z."<br/>"; // 输出 25 $i=5; $i *= 5; echo $i."<br/>"; // 输出 25 $j=10; $j /= 5; echo $j."<br/>"; // 输出 2 $k=15; $k %= 4; echo $k."<br/>"; // 输出 3 ?>
