Implementation code of phpradio single-region acquisition and holding value

In php, the method for reading single-choice radio values is the same as that for retaining single-choice button values in php. Php read single-choice button radio value
The code is as follows:



Php read single-choice button radio value





If ($ _ POST)
{
Echo 'Select a single Select', $ _ POST ['radiogroup1'];
// Since the attributes of a single-choice button can only be selected at the same time, it is OK to directly change their names to the same one.
}
?>

The main idea is how to maintain the value of a single-choice button in php.
The code is as follows:
/>男
/> Female

We also recommend that you do not use Chinese characters for identification. 0, 1 represents male and female.
