极客笔记PHP bindec()函数
PHP bindec()函数是一个数学函数，用于将二进制数转换为十进制数。它返回二进制字符串的十进制值。
注意：要通过使用decbin()函数将十进制数转换为二进制数。
语法
bindec(binary_string);
| 参数 | 描述 | 必需/可选 |
|---|---|---|
| binary_string | 指定要转换的二进制字符串，参数值必须是字符串。 | 必需 |
示例1
<?php
binary='110011';
echo "Your binary number is : ".binary;
echo "<br>"."By using ?bindec()' function your decimal number is :".bindec($binary);
?>
输出：
Your binary number is : 110011
By using bindec()' function your decimal number is :51
示例2
<?php
binary='01';
echo "Your binary number is : ".binary;
echo "<br>"."By using 'bindec()' function your decimal number is :".bindec($binary);
?>
输出：
Your binary number is : 01
By using 'bindec()' function your decimal number is :1
示例3
<?php
binary='000110011';
echo "Your binary number is : ".binary;
echo "<br>"."By using 'bindec()' function your decimal number is :".bindec($binary);
?>
输出：
Your binary number is : 000110011
By using 'bindec()' function your decimal number is :51
示例4
<?php
binary='1010';
echo "Your binary number is : ".binary."<br>";
echo var_dump(bindec($binary));
?>
输出：
Your binary number is : 1010
int(10)
示例5
<?php
binary='10000';
echo "Your binary number is : ".binary."<br>";
echo "By using 'bindec()' function your decimal number is :".bindec($binary);
?>
输出：
Your binary number is : 10000
By using 'bindec()' function your decimal number is :16
