<para>
|
|
This function returns a string or an array with all occurences of
|
|
<parameter>search</parameter> in <parameter>subject</parameter>
|
|
replaced with the given <parameter>replace</parameter> value. If
|
|
you don't need fancy replacing rules, you should always use this
|
|
function instead of <function>ereg_replace</function> or
|
|
<function>preg_replace</function>.
|
|
</para>
|
|
<para>
|
|
In PHP 4.0.5 and later, every parameter to
|
|
<function>str_replace</function> can be an array.
|
|
</para>
|
|
<para>
|
|
If <parameter>subject</parameter> is an array, then the search
|
|
and replace is performed with every entry of
|
|
<parameter>subject</parameter>, and the return value is an array
|
|
as well.
|
|
</para>
|
|
<para>
|
|
If <parameter>search</parameter> and
|
|
<parameter>replace</parameter> are arrays, then
|
|
<function>str_replace</function> takes a value from each array
|
|
and uses them to do search and replace on
|
|
<parameter>subject</parameter>. If
|
|
<parameter>replace</parameter> has fewer values than
|
|
<parameter>search</parameter>, then an empty string is used for
|
|
the rest of replacement values. If <parameter>search</parameter>
|
|
is an array and <parameter>replace</parameter> is a string; then
|
|
this replacement string is used for every value of
|
|
<parameter>search</parameter>.

<function>str_replace</function> was added in PHP 3.0.6, but was

buggy up until PHP 3.0.8.

As of <literal>PHP 5.0</literal> the number of matched and replaced
|
|
<parameter>needle</parameter>s will be returned in
|
|
<parameter>count</parameter> which is passed by reference.
