PHP how to save file with "\"?

Question

PHP

I have a string with "=" instead of "\u003d". I fixed it with str_replace. But when I saved it to a json file, the "\" in "\u003d" was replaced with "\\". If it is displayed using echo, then this is not observed. How to save a file normally so that there is only one "\"?

Normal - this is just when you have such characters escaped. Any normal JSON parser reads correctly, and when the data is deserialized, there is no more escaping backslash.
