Makes a unified diff of two strings.
Indicates how many lines of context you want to include in the diff result.
Set this parameter to TRUE if you want to minimalize the size of the diff (can take a long time).
Example 1. xdiff_string_diff() example
The following code makes unified diff of two articles.
Note: This function doesn't work well with binary strings. To make diff of binary strings use xdiff_string_diff_binary().
