–(int):将值转换为整数类型。 –(float) 或 (double):将值转换为浮点数类型。 –(string):将值转换为字符串类型。 –(array):将值转换为数组类型。 –(bool) 或 (boolean):将值转换为布尔类型。 示例代码: “`php $value = 5; $intValue = (int) $value; $floatValue = (float) $value; $str...
可以使用多种方法,以下是一些常用的方法: 1. 使用强制类型转换:可以使用`(int)`或`(float)`将字符串转换为整数或浮点数。例如: ```php $str = "123"; $int =...
function convertToBytes($size) { $unit = strtolower(substr($size, -2)); $value = (int) $size; switch ($unit) { case 'kb': $value *= 1024; break; case 'mb': $value *= 1024 * 1024; break; case 'gb': $value *= 1024 * 1024 * 1024; break; case 'tb': $value *= 1024...
Download:PHP IPv6 to 128 bit ints Note If you just want to store the IP addresses in MySQL you can store them as a VARBINARY(16) and use the built in PHPinet_ptonandinet_ntopfunctions. They will convert IPv6 and IPv4 addresses into binary and back again. ...

So if you’re handling large numbers stored as float (especially on 32-bit systems where 32-bit int overflow will implicitly convert to float) and getting strange bugs, remember that string conversion might let you down. sprintf(), on the other hand, is always a friend when it comes to ...
