在这段代码中,我们首先定义了一个Ascii码值,并将其强制转换为char类型,得到对应的字符。 步骤2:将char类型转换成String类型 // 将char类型转换成String类型Stringstr=String.valueOf(ch);// 输出结果System.out.println("String类型结果:"+str); 1. 2. 3. 4. 5. 在这段代码中,我们使用String类的valueOf...
$string = ‘Hello, World!’; $length = strlen($string); for ($i = 0; $i < $length; $i++) { $char = $string[$i]; $ascii = ord($char); echo "The ASCII value of $char is $ascii" . PHP_EOL;}```总结在PHP中获取ASCII码可以使用ord()函数、chr()函数、printf()函数、ASCII码...

ASCII 码使用指定的7 位或8 位二进制数组合来表示128 或256 种可能的字符。标准ASCII 码也叫基础ASCII码,使用7 位二进制数(剩下的1位二进制为0)来表示所有的大写和小写字母,数字0 到9、标点符号,以及在美式英语中使用的特殊控制字符。其中: 0～31及127(共33个)是控制字符或通信专用字符(其余为可显示字符...
