#What does = mean in PHP?

#The basic assignment operator in PHP is "=". This means that the right-hand assignment expression sets the value of the left-hand operand.

Example:

<?php 
$x=17; 
echo $x; // 输出 17$y=17; 
$y += 8;
echo $y; // 输出 25$z=17;
$z -= 8;
echo $z; // 输出 9$i=17;
$i *= 8;
echo $i; // 输出 136$j=17;
$j /= 8;
echo $j; // 输出 2.125$k=17;
$k %= 8;
echo $k; // 输出 1?>
