Надо ли повторно экранировать массив после разбора его на строку?



Выражение такого вида :



$col = $this->res($column); // res() - экранирует символы (в зависимости от типа, массива или строки)is_array($column)? $cols = implode(',', $col) : $cols = $col; // Если массив ( разбить его на строку), если строка - оставить

Или все-таки лучше сделать так


is_array($column)? $cols = implode(',', $this->res($col) ) : $cols = $this->res($col);

повторно не нужно, экранированные символы никуда не денутся.


как примеры

implode(',', array(1,'\r\n',2,3));// вернет строку // 1,\r\n,2,3implode(',', array(1,"\r\n",2,3));// вернет строку c переносом строки// 1,// ,2,3
