Name

str_replace

Synopsis

mixed str_replace(mixed search, mixed replace, mixed string[, int &count])

Searches for all occurrences of search in string and replaces them with replace. If all three parameters are strings, a string is returned. If string is an array, the replacement is performed for every element in the array and an array of results is returned. If search and replace are both arrays, elements in search are replaced with the elements in replace with the same numeric indices. Finally, if search is an array and replace is a string, any occurrence of any element in search is changed to replace. If supplied, count is filled with the number of instances replaced.
