PHPで複数の文字列の中から特定の文字列を置換（変換）する方法

Question

実現したいこと

表題のとおり、PHPで以下のような文字列を用意します。
特定の部分を変換したいのですが、どのような方法があるでしょうか。

a:20:{i:0;a:4:{s:7:"id01";s:12:"no010";s:9:"date";s:8:"20120721";s:9:"name";s:6:"ソング";s:4:"code";s:169:"track:01_music:1_min:1500_dist:2_news:1_class:1_copy:1_ninki:5_giant:1_cd:01144_icd:00379_ocd:061800_song:1995103211_gmc:1985109002_human:2010102688_label:4__0:0:9";}

前提

PHP version 7.0ですが、問いません。
事前にわかっている情報は 、「id07」、「no016」が含まれているところの「cd:01095」の「01095」を「07111」に変換したいということです。

$search = '_cd:';
$replace = '07111';
$subject = str_replace($search, $replace, $text);
echo $subject;

問題となっていること

「id07」、「no016」が含まれているところを特定し、「_cd:」以降の数値を変換できていません。

Answer 1

こういうことでしょうか？

$pattern="/(id07.*?no016.*?1_cd:)(\d+)/";
print preg_replace($pattern,'${1}07111',$text);
