为什么转义字符（\）出现在一个表单字段中而不出现在另一个表单字段中？

Question

I've been building a database input form. There are three fields for notes. They were all build at the same time. They have the same logic & class system - but one of them is returning with escape marks when I update the record, e.g. I enter

1
2
3

and the updated record returns

1
2
3

I'm confused as the other return the text as formatted. Can you sugggest why this is happening?

Answer 1

As it is, your question lacks a lot of crucial information. Obviously, if everything is done identically, the data will be the same as well. Additionally, you probably don't mean that there are escape marks in your data (or do you?). In that case, you must have explicitly called a function to convert line breaks into a string containing the characters '\' and 'n'.

Lacking any code, I assume that you display your data differently; once using a normal echo and once using something like var_dump.
