PHP Function ereg_replace()
string ereg_replace (string pattern, string replacement, string originalstring);
Definition and Usage
The ereg_replace() function searches for string specified by pattern and replaces pattern with replacement if found. The ereg_replace() function operates under the same premises as ereg(), except that the functionality is extended to finding and replacing pattern instead of simply locating it.
Like ereg(), ereg_replace() is case sensitive.
After the replacement has occurred, the modified string will be returned.
If no matches are found, the string will remain unchanged.
Following is the piece of code, copy and paste this code into a file and verify the result.
$copy_date = "Copyright 1999";
$copy_date = ereg_replace("([0-9]+)", "2000", $copy_date);
