如何使用Carbon在传递到视图前修改日期格式（Laravel场景）

Got it, let's swap out those strtotime() and date() calls with Carbon—Laravel's built-in date utility makes this way cleaner and more reliable. Here's how to adjust your graphheheByDate method:

Updated Code #

public function graphheheByDate(Request $request, $companyID) 
{ 
    $companyID = $this->decode($companyID); 
    $matchs = DiraChatLog::whereBetween('date_access', [$request->from, $request->to])
        ->orderBy('date_access', 'asc')
        ->get(); 

    $a = [];
    foreach ($matchs as $match) { 
        // Use Carbon to format the date directly
        $newformat = $match->date_access->format('Y-m-d'); 
        $a[$newformat] = $this->testing($newformat, $match); 
    } 

    // Removed the dd($a) since it was halting execution before processing data for the view
    $user = array_values($a); 
    $dates = array_keys($a); 

    // Continue with your existing logic to pass data to the view
    return view('your-target-view', compact('user', 'dates'));
}

Key Details to Note: #

• Automatic Carbon Conversion: Ensure your DiraChatLog model is set up to turn the date_access field into a Carbon instance automatically.
  • For Laravel 7 and earlier, add this property to the model:

    protected $dates = ['date_access'];
    

  • For Laravel 8+, use the $casts property instead:

    protected $casts = ['date_access' => 'datetime'];
    

  • If you can't modify the model, you can still parse the date manually:

    $newformat = \Carbon\Carbon::parse($match->date_access)->format('Y-m-d');
    

• Simpler, Safer Syntax: Carbon removes the need for manual timestamp conversion—calling format() directly on the date instance is more readable and less likely to cause edge-case errors.
• Fix Execution Flow: The original dd($a) was stopping your code before you could prepare $user and $dates for the view, so I removed that line to let the rest of the logic run.
