(PHP 3 >= 3.0.6, PHP 4, PHP 5)str_replace -- Replace all occurrences of the search string with the replacement string
This function returns a string or an array with all occurrences of
replaced with the given
replace value. If you
don't need fancy replacing rules (like regular expressions), you should
always use this function instead of ereg_replace() or
As of PHP 4.0.5, every parameter in str_replace() can be an array.
In PHP versions prior to 4.3.3 a bug existed when using arrays as
subject is an array, then the search
and replace is performed with every entry of
subject, and the return value is an array
replace are arrays, then
str_replace() takes a value from each array
and uses them to do search and replace on
replace has fewer values than
search, then an empty string is used for
the rest of replacement values. If
is an array and
replace is a string, then
this replacement string is used for every value of
search. The converse would not make sense,
are arrays, their elements are processed first to last.
