将字符串转换为数字，代码如下−
示例
<?php $str = "150"; $num = (int)$str; echo "Number (Converted from String) = $num"; ?>
输出
将产生以下输出−
Number (Converted from String) = 150
示例
现在让我们看另一个例子 −
<?php $str = "100.56"; echo "String = $str"; $num = floatval($str); echo "
Number (Converted from String) = $num"; ?>
输出
这将产生以下输出−
String = 100.56 Number (Converted from String) = 100.56
