Php generates random strings

You can specify whether it is a pure number, a pure letter, or a combination.

You can specify the length.

The Code is as follows:

Function rand_zifu ($ what, $ number ){
$ String = '';
For ($ I = 1; $ I <= $ number; $ I ++ ){
// Hybrid
$ Panduan = 1;
If ($ what = 3 ){
If (rand (1, 2) = 1 ){
$ What = 1;
} Else {
$ What = 2;
}
$ Panduan = 2;
}

// Number
If ($ what = 1 ){
$ String. = rand (0, 9 );
} Elseif ($ what = 2 ){
// Letter
$ Rand = rand (0, 24 );
$ B = 'a ';
For ($ a = 0; $ a <= $ rand; $ a ++ ){
$ B ++;
}
$ String. = $ B;
}
If ($ panduan = 2) $ what = 3;
}
Return $ string;
}
Echo rand_zifu (3,10 );
