/**

* Navigates through an array and removes slashes from the values.

*

* If an array is passed, the array_map() function causes a callback to pass the

* value back to the function. The slashes from this value will removed.

*

* @since 2.0.0

*

* @param mixed $value The value to be stripped.

* @return mixed Stripped value.

function stripslashes_deep($value) {

} elseif ( is_object($value) ) {

}

} elseif ( is_string( $value ) ) {

}

// array (size=3)

// 0 => string 'I\'m bean' (length=9)

// 1 => string 'I\'m bean' (length=9)

// 2 =>

// array (size=2)

// 0 => string 'I\'m bean' (length=9)

// 1 => string 'I\'m bean' (length=9)
