php converts binary to 16 Method of converting strings:
Method 1: Use base_convert() function
base_convert() function to convert numbers between arbitrary bases.
base_convert($binary_string,$frombase,$tobase);
$binary_string Required. Specifies the binary number to be converted.
#$frombase Required. Specifies the original base of the number. Between 2 and 36 (inclusive). Numbers above decimal are represented by the letters a-z, such as a for 10, b for 11, and z for 35.
#$tobase Required. Specifies the base to be converted. Between 2 and 36 (inclusive). Numbers above decimal are represented by the letters a-z, such as a for 10, b for 11, and z for 35.
Example:
<?php header("content-type:text/html;charset=utf-8"); $num1="0011"; $num2="11000110011"; echo "二进制 ".$num1." 转换成十六进制 ".base_convert($num1,2,16)."<br>"; echo "二进制 ".$num2." 转换成十六进制 ".base_convert($num2,2,16)."<br>"; ?>
2. Use bindec() dechex() function
bindec($binary_string)
Function converts binary number $binary_string
to decimal number.
dechex($number)
The function converts the decimal number $number
into a hexadecimal string.
<?php header("content-type:text/html;charset=utf-8"); $num1="0011"; $num2="11000110011"; echo "二进制 ".$num1." 转换成十六进制 ".dechex(bindec($num1))."<br>"; echo "二进制 ".$num2." 转换成十六进制 ".dechex(bindec($num2))."<br>"; ?>
