substr_replace

Synopsis

string substr_replace(mixed string, mixed replace, mixed offset[, mixed length])

Replaces a substring in string with replace. The substring replaced is selected using the same rules as those of substr(). If string is an array, replacements take place on each string within the array. In this case, replace, offset, and length can either be scalar values, which are used for all strings in string, or arrays of values to be used for each corresponding value in string.
