bin2hex()函数是一个字符串函数,用于将给定的ASCII字符串转换为十六进制值。
它接受字符串并返回十六进制转换后的字符串。
语法:
bin2hex(string);
例子:
Input: str = Hello world Output: hex_str = 48656c6c6f20776f726c64 Input: str = ABC 123 @#$%. XYZ Output: hex_str = 4142432031323320402324252e2058595a
PHP代码:
<?php $str = "Hello world"; $hex_str = bin2hex($str); //打印两个字符串 echo ("str = " . $str . "\n"); echo ("hex_str = " . $hex_str . "\n"); $str = "ABC 123 @#$%. XYZ"; $hex_str = bin2hex($str); //打印两个字符串 echo ("str = " . $str . "\n"); echo ("hex_str = " . $hex_str . "\n"); ?>
输出结果
str = Hello world hex_str = 48656c6c6f20776f726c64 str = ABC 123 @#$%. XYZ hex_str = 4142432031323320402324252e2058595a
