replace \n with actual new line character code

问题

I'm pulling content from a DB that has been sanitized using mysql_real_escape_string. Accordingly the new line characters now appear as "\n". The issue is that this content is displayed to users inside a < pre > tag so I cannot replace \n with < br/> for instance.

I suppose I could replace \n with the actual utf8 character code before inserting the result inside the < pre>.

Can somoneone assist here? Not using mysql_real_escape_string isn't really an option due to security policy.

Thanks.

回答1:

echo '<pre>'.str_replace('\n', "\n", $string).'</pre>';

回答2:

str_replace("\\n","\n",$data);

回答3:

why not ...

echo str_replace('\\n', PHP_EOL, "few lines\nof text here,\nblah, blah! etc!");

If you've not done anything to the raw data pulled back from the database then the ptoblem is that it has been 'sanitized' twice when inserted.

This might help a bit:

echo('test\ntest'); shows as

test test

but echo("test\ntest"); shows as

test
