How can I solve the problem of whether socket_write in php can directly send hexadecimal data?

In php, can socket_write directly send hexadecimal data? if the hexadecimal data is directly sent, he will first Convert hexadecimal to hexadecimal and then split the string, calculate the split string in hexadecimal notation and send the code as follows: $ str = 0xFA; & nbsp; socket_write ($ connection, $ str ); the data obtained through the packet capture tool is whether socket_write in php 3 can directly send hexadecimal data.
If the hexadecimal data is directly sent, it will first convert the hexadecimal data into a hexadecimal data, then split the string, calculate the hexadecimal string after the split, and finally send the data, the code is as follows:

$ Str = 0xFA;
Socket_write ($ connection, $ str );

The data obtained through the packet capture tool is 32 35 30, for example:



Is there a way to directly send hexadecimal data, that is, the data I captured through the packet capture tool is FA?
