"Random" number being generated along with md5 hash

Question

I am developing an application in Laravel and at a certain moment I need to generate a value in MD5 to assign to a field in the database.

The problem is that when generating this hash of MD5, a "random number" is appearing and is entering the variable, instead of entering the variable the hash created. Behold:

 if($this->emptyField === 0)
 {
   
     //Criando um id do lote
     $fileId = md5(time() . rand(0, 9999) . time());
     print_r($fileId);
 }

See what is generated:

If you notice there, 4 numbers (9634) are generated along with the MD5 hash. When you enter the database, only these 4 numbers enter the column.

Sometimes it happens to only generate the MD5 hash even.

The field in the database is varchar(100). And the database is Mysql.

Could you help me ?

Answer 1

Dear, The hash generated by md5 contains 32 characters, your output in pewview is correct, there is nothing wrong. to check, check the Rand in a separate variable, then join it with the time() in a separate string, print both before generating the md5, generate the md5 and then re-generate with the previous outputs on a website that provides md5 for conference purposes, and you’ll see it’s all right. Thus:

//Criando um id do lote
       $father = rand(0, 9999);
       print_r($father);
       echo "<br>";
       $pre_print = (time() . $father . time());
       print_r($pre_print);
       echo "<bR>";
       $fileId = md5($pre_print);
       print_r($fileId);
