Implementation to detect if there is a specific tag in html in php
1. When publishing a document to WeChat, WeChat response failed: error code: 45166, error message: Invalid content hint:[pzRHda0286d228]Rid: 61041ffe-5cefd269-6c9611ff.
2. The final analysis shows that the content of the document contains the label: Caused by MMPVoice. The content of the document is as follows:
内容contentcontentcontentcontentcontentcontentcontentcontentcontentcontentcontentcontent
3. I finally decided to check whether there is a tag in the html before calling the WeChat interface: mpvoice, if it exists, then do not follow the follow-up process to save users waiting time
4. The final implementation code is as follows:
$mpvoicePattern = "/]+)>(?:(?!<\/mpvoice>)[\s\S])*<\/mpvoice>/s";
$audioPattern = "/]+)>(?:(?!<\/audio>)[\s\S])*<\/audio>/s";
preg_match($mpvoicePattern, $item['content'], $mpvoiceMatches);
preg_match($audioPattern, $item['content'], $audioMatches);
if (!empty($mpvoiceMatches)) {
$this->addError($attribute, Yii::t('error', Yii::t('error', Yii::t('error', '202247'), ['tag' => 'mpvoice'])));
break;
}
if (!empty($audioMatches)) {
$this->addError($attribute, Yii::t('error', Yii::t('error', Yii::t('error', '202247'), ['tag' => 'audio'])));
break;
}
5. Print $MPVOICEMATCHES and $AUDIOMATCHES respectively. The results are as follows

6. When only the text content such as <mpvoice, /mpvoice>, audio, etc. is included in the content, instead of closed and complete HTML tags, regular matching will not be triggered. as shown in Figure 1
