    <p>I have the following function to generate a random string:</p> <pre><code>public function generateString(){ function generateCharacter () { $possible = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"; $char = substr($possible, mt_rand(0, strlen($possible)-1), 1); return $char; } function generateNumber () { $GUID = generateCharacter().generateCharacter().generateCharacter().generateCharacter().generateCharacter().generateCharacter().generateCharacter().generateCharacter().generateCharacter(); return $GUID; } $string = generateNumber(); return $string; } </code></pre> <p>I then need to be able to generate these random strings x amount of times using a for loop and insert them into my MySQL table:</p> <p><code>$how_many</code> is where i would select how many times i want to loop.</p> <pre><code>for ($i = 1; $i &lt;= $how_many; $i++) { $random = $this-&gt;generateString(); $query_params = array( ':code' =&gt; $random, ); $query = " INSERT INTO table ( code ) VALUES ( :code ) "; try { $stmt = DB::get()-&gt;prepare($query); $stmt-&gt;execute($query_params); } catch(PDOException $ex) {} } </code></pre> <p>The above gives me an error though of:</p> <pre><code>Fatal error: Cannot redeclare generateCharacter() (previously declared in.... </code></pre> <p>I know i cannot have the function in the for loop otherwise i get this error but if i have it outside the loop it just generates the string once and inserts the same string everytime.</p> <p>How can i get it so each insert in my loop is a new random string?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
