Regex 替换替代方案的PHP正则表达式

我有一个需求，我正试图找到一个正则表达式模式来替换代码。我知道我可以得到正常的正则表达式来查找和替换文本，但要求是交替查找和替换实例

比如说,

{code}
UPDATE tenants SET end_user_uuid = '32392464c8a19a15dd8dc982ae3d574b' WHERE end_user_uuid = '9e194bfeace6c2d17cc71cc15e84f93a' AND instance_id = '265358' AND domain = 'automobieljansen';
{code}

Rollback: 

{code}
UPDATE tenants SET end_user_uuid = '9e194bfeace6c2d17cc71cc15e84f93a' WHERE end_user_uuid = '32392464c8a19a15dd8dc982ae3d574b' AND instance_id = '265358' AND domain = 'automobieljansen';
{code}

Find:    \{code\}(.*?)\{code\}
Replace: <pre>$1</pre>

这是原文。我需要将

{code}

的第一个实例替换为

<pre>
UPDATE tenants SET end_user_uuid = '32392464c8a19a15dd8dc982ae3d574b' WHERE end_user_uuid = '9e194bfeace6c2d17cc71cc15e84f93a' AND instance_id = '265358' AND domain = 'automobieljansen';
</pre>

Rollback: 

<pre>
UPDATE tenants SET end_user_uuid = '9e194bfeace6c2d17cc71cc15e84f93a' WHERE end_user_uuid = '32392464c8a19a15dd8dc982ae3d574b' AND instance_id = '265358' AND domain = 'automobieljansen';
</pre>

预期结果

更新租户集end_-user_-uuid='32392464C8A19A115DD8DC982AE3D574B'，其中end_-uuid='9e194bfeace6c2d17cc71cc15e84f93a'和instance_-id='265358'，domain='automobieljansen'；
回降：
更新租户集end_-user_-uuid='9e194bfeac6c2d17cc71cc15e84f93a'，其中end_-uuid='32392464c8a19a15dd8dc982ae3d574b'，instance_-id='265358'，domain='automobieljansen'；

有没有关于如何轻松做到这一点的帮助

在正则表达式模式下，尝试以下查找和替换操作：

<pre>
UPDATE tenants SET end_user_uuid = '32392464c8a19a15dd8dc982ae3d574b' WHERE end_user_uuid = '9e194bfeace6c2d17cc71cc15e84f93a' AND instance_id = '265358' AND domain = 'automobieljansen';
</pre>

Rollback: 

<pre>
UPDATE tenants SET end_user_uuid = '9e194bfeace6c2d17cc71cc15e84f93a' WHERE end_user_uuid = '32392464c8a19a15dd8dc982ae3d574b' AND instance_id = '265358' AND domain = 'automobieljansen';
</pre>

在PHP中-搜索开始和结束

{code}

并捕获它们之间的文本，在

之间输出，$text）；

输出：

更新租户集end_-user_-uuid='32392464C8A19A115DD8DC982AE3D574B'，其中end_-uuid='9e194bfeace6c2d17cc71cc15e84f93a'和instance_-id='265358'，domain='automobieljansen'；
回降：

echo preg_replace('/{code}(.*?){code}/s', '<pre>$1</pre>', $text);

<pre>
UPDATE tenants SET end_user_uuid = '32392464c8a19a15dd8dc982ae3d574b' WHERE end_user_uuid = '9e194bfeace6c2d17cc71cc15e84f93a' AND instance_id = '265358' AND domain = 'automobieljansen';
