Prepares an item before it is being written and escapes fields.
All characters from \000 to \037 (this includes new line and tab characters) as well as the backslash (`\`) and the double quote (`"`) are escaped. Literal Windows CRLFs (`\r\n`) are converted to LFs (`\n`) to improve cross platform compatibility. Escaped single quotes (`'`) are unescaped as they should not need to be. Double escaped characters are maintained and not escaped once again.

Parameters

  • array $item

Returns

array
