[SOLVED] Reading/Writing to text file help.

[shazman]

I have a page that gets it's content from a text file. When the user modifies the page's content and uses a single quote anywhere, it puts a slash in front of it.

Example: When you type "We're" it prints "We/'re" to the text file and displays that on the page.

How can I make it not print the slashes. It also does this for double quotes. This makes things difficult when the user is adding a hyperlink.

before writing text into a file, use addslashes().... then when retrieving, use stripslashes() before displaying.

 

did it work?

Use this:

 

function unescape_data($string) {

  if (get_magic_quotes_gpc()) {

      return stripslashes($string);

   }

  else {

      return $string;

  }

}

 

You shouldn't need to escape data for writing it directly to a text file.

bluejay002 is right. `

When you type "We're" it prints "We/'re"

should be

When you type "We're" it prints \"We\'re\"

involking the addslashes() method

There's no reason to escape content in a text file. 

 

The whole purpose for magic_quotes_gpc was to prevent database injection attacks, because php developers, in the day of php 3, apparently couldn't be trusted to be smart enough to prevent it.  It has nothing to do with text files, and should most certainly be disabled if possible.  In php 6 magic_quotes_gpc won't even exist (along with register_globals), so this won't even be an issue.

 

Darkwater's response is a viable method of removing the slashes if you can not disable the directive in php.ini.

Indeed. =P  Never rely on magic_quotes_gpc.

yeah... i forgot, my bad.

 

i looked back with my previous codes... and i did not use addslashes() at all when saving to a file.

 

thanks,

Thanks. Everything is working great.

Any time.
