PHP - Function ereg_replace()

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.

Return Value

  • After the replacement has occurred, the modified string will be returned.

  • If no matches are found, the string will remain unchanged.
