Using PHP to generate random user names in batches

Basically handle the hand, the above generated 2.7W a random user name, hehe, to ensure that you use.

Generate a number of 6 ~ 16 user names, mainly text operations, the colleague premise is to have a string package. consists of three programs.

Program one: Responsible for the random extraction of data from the dictionary, write a new file. (1.php)

<?php
* * Extract the random value from the dictionary file.

File1 = "./words.dic";
File2 = "./common_pass_mini.dic";
File3 = "./sys_month_date.dic";
Rfile = "./5.dic";
n = 2000;

Extracting dictionaries
Basef = file (file1);
EXTF = file (file2);
EXTF2 = file (file3);
Bf_sum = (count (Basef)-1);
Ef_sum = (count (EXTF)-1);
Ef2_sum = (count (EXTF2)-1);

Get random user name
for (i=0; i<n; i++)
{
bn = Crand (0, bf_sum);
En = Crand (0, ef_sum);
EN2 = Crand (0, ef2_sum);
Name = Basef[bn]. " _ ". Extf[en];
Name = Str_replace ("\ r \ n", "", name);
all_name[] = name;
}

Write to File
result = Implode ("\ r \ n", all_name);
fp = fopen (Rfile, "A +") or Die (' Open rfile failed ');
if (fwrite (FP, result)) {
Echo ' Write user succeed! ';
} else {
Echo ' Write user failed ';
}

Generating random number functions
function Crand (start, end)
{
Return Mt_rand (start, end);
}
?>

Program two: Responsible for merging the results of several files generated above. (2.php)

<?php
/* Merge all Build results knowsky.com*/

Result_file = "./result.dic";

fp = fopen (Result_file, "A +") or Die ("Open result_file failed");

Combined 1.dic ~ 5.dic
for (I=1; i<=5; i++)
{
Cur_file = file_get_contents (i.). DiC ");
Fwrite (FP, cur_file);
}

Combined 10.dic ~ 11.dic
for (i=10; i<=11; i++)
{
Cur_file = file_get_contents (i.). DiC ");
Fwrite (FP, cur_file);
}
Fclose (FP);
Echo ' Write succeed ';

?>

Program three: Responsible for filtering duplicate values and values that are not part of 6~16 and generating final results (3.php)

<?php
/* Generate final result * *

File = "./result.dic";
target = "./target.dic";

Remove duplicate values
Files = file (file);
Files = array_unique (files);

Determines whether the value is greater than 6 bits or less than 16 bits
sum = count (files);
for (i=0; i<sum; i++)
{
if (strlen (Files[i]) >=6 && strlen (files[i)) <=16) {
Rs[] = files[i];
} else {
Continue
}
}

Write to destination file
result = Implode ("", RS);
FP = fopen (Target, "A +") or Die ("Open target Failed");
Fwrite (FP, result);
Echo ' Write succeed ';

?>
