To rectify this, declare $pass as an array and use implode() to convert it to a string.</p><p><strong>Security Warning:</strong></p><p>It's crucial to note that rand() is not cryptographically secure for creating passwords. Consider using more secure alternatives for generating random passwords.</p><p><strong>Character Repetition Issue:</strong></p><p>The code produces only 'a's potentially because the variable $alphabet does not include the letter 'a'.
