Automatic Addslashes

I do

copy tmp from '/home/algobit/product.txt

tmp ia a table with one record (line varchar(255))

in product.txt I have many line as:

2;"100";"Parmigiano Reggiano";"Parmigiano Reggiano stagionato 2
anni";4;"parmigiano4.jpg";2;"Fette 1 Kg";0.18;1;1.00;"true"

Then with "select * from tmp" the result is exactly like in the original
file

2;"100";"Parmigiano Reggiano";"Parmigiano Reggiano stagionato 2
anni";4;"parmigiano4.jpg";2;"Fette 1 Kg";0.18;1;1.00;"true"

But when i fetch in a variable the rercords (with php) i READ in the
variable

2;\"100\";\"Parmigiano Reggiano\";\"Parmigiano Reggiano stagionato 2
anni\";4;\"parmigiano4.jpg\";2;\"Fette 1 Kg\";0.18;1;1.00;\"true\"

the question is : The SLASH are effectively in the record ?
