How to convert a String to an array(the data from PHP)

Projects Programming
1

My php file will echo some string in a webpage.

And the data has been stored into a string use the following code.
String line = client.readStringUntil

The problem is that eventually I want to store the format as an array. I can call the binary digits of different fields for some control, it doesn't matter if it is a string array. As long as it can be converted into an array.

char line[13] = client.readStringUntil It can't work like this .
I originally wanted to save the data format displayed by the php web page as an array to define it directly,
like this:{"0","0","0","0","0","0","0","0","0","0","0","0","0"} 13 values are read from MySQL
but he was a string after all.

Can someone clear me about this ?

You can use myString.toCharArray(buf, len) or myString.getBytes(buf, len)

The principles equally apply to networking (just replace Serial by client).

The use of strtok() allows you to store each element in an array.
