PHP gmp_import()函数

PHP GMP导入函数将字符串值转换为二进制值．我们可以使用gmp_import()函数操作字符串数据的数学函数。

语法

PHP GMP导入函数的语法如下所示。

参数

如上语法所示，GMP gmp_import()函数接受三个参数:

美元的数字: GMP gmp_import()函数的基本参数。它是函数将从字符串值中导入的数字。
num_size美元:该参数表示每个二进制数据中有多少字节。有时，main参数与options参数一起工作。该参数的默认值为1。
option_num美元: GMP MSW FIRST |缺省设置为GMP NATIVE INDIAN。

返回值

如果函数有效，则返回一个字符串。如果它不起作用，则返回FALSE。

例子

下面的示例展示了使用不同数据的多种类型的导入函数操作。

例二:下面的示例显示了具有基本值的gmp_import()函数。给定的参数显示负数和正数的导入值。
