<para>
|
|
This function returns a copy of <parameter>str</parameter>,
|
|
translating all occurrences of each character in
|
|
<parameter>from</parameter> to the corresponding character in
|
|
<parameter>to</parameter> and returning the result.
|
|
</para>
|
|
<para>
|
|
If <parameter>from</parameter> and <parameter>to</parameter> are
|
|
different lengths, the extra characters in the longer of the two
|
|
are ignored.

<function>strtr</function> can be called with only two
|
|
arguments. If called with two arguments it behaves in a new way:
|
|
<parameter>from</parameter> then has to be an array that contains
|
|
string -> string pairs that will be replaced in the source
|
|
string. <function>strtr</function> will always look for the
|
|
longest possible match first and will *NOT* try to replace stuff
|
|
that it has already worked on.

<![CDATA[

$trans = array("hello" => "hi", "hi" => "hello");

|
echo strtr("hi all, I said hello", $trans) . "\n";
|
|
]]>
|
|
</programlisting>
|
|
</informalexample>
|
|
This will show: "hello all, I said hi",

<note>

<simpara>
|

This optional <parameter>to</parameter> and

<parameter>from</parameter> parameters were added in PHP 4.0.0
