Replacing a phrase containing a variable

[etrader]

I have phrases in a string with the structure of "Note: some description" I want to replace "Note with (, but how can I replace the second " with )?

[BlueSkyIS]

use str_replace twice?

 

$string = '"Note: some description"';
$string = str_replace('"Note: ','(', $string);
$string = str_replace('"',')', $string);

echo "string: $string";

Thanks for your suggestion, but this phrase is within a long string; the string is not limited to this phrase. I need a replacing method to look for "Note: ..... "

same thing. neither the length of the string or other content in the string matter.

 

<?php
$string = 'AS FASDGASPING asdg aosgiha sgasgoiasrog rag 09u0er70   asr gas "Note: some description" asdga0idsajg0 s0gasrgho aisg';
$string = str_replace('"Note: ','(', $string);
$string = str_replace('"',')', $string);

echo "string: $string";
?>

output:
string: AS FASDGASPING asdg aosgiha sgasgoiasrog rag 09u0er70 asr gas (some description) asdga0idsajg0 s0gasrgho aisg
