PHP:传递变量给函数
PHP: Pass variable to function
看起来很简单(也许),但我需要将一个函数中接收到的变量传递给另一个函数。这是我的代码:
PD:我使用 Laravel Eloquent 的作用域
class myParentModel extends Model {
public function scopeMyScope($query, $VAR_I_WANT_TO_PASS=[]) {
return $query->with('model'])->whereHas('model', function($q, $VAR_I_WANT_TO_PASS=[]) {
$q->where('colum1',$VAR_I_WANT_TO_PASS[0])->where('colum2',$VAR_I_WANT_TO_PASS[1])->where('colum3',$VAR_I_WANT_TO_PASS[2]);
})->take(10);
}
}
我想这样做:
$result = myParentModel::myScope([3,1,6])->get();
我使用 use
:
解决了这个问题
class myParentModel extends Model {
public function scopeMyScope($query, $VAR_I_WANT_TO_PASS) {
return $query->with('model'])->whereHas('model', function($q) use ($VAR_I_WANT_TO_PASS) {
$q->where('colum1',$VAR_I_WANT_TO_PASS[0])->where('colum2',$VAR_I_WANT_TO_PASS[1])->where('colum3',$VAR_I_WANT_TO_PASS[2]);
})->take(10);
}
}
