Php uses strip_tags () to remove html tags.

Php uses strip_tags () to remove html tags.

The example in this article describes how php uses strip_tags () to remove html tags. We will share this with you for your reference. The details are as follows:

$ Subject = strip_tags ($ newsRs ['content']); // remove the html Tag $ pattern = '/\ s /'; // remove blank $ content = preg_replace ($ pattern, '', $ subject); $ seodata ['articledescription'] = mb_substr ($ content, 0, 80 ); // intercept 80 Chinese Characters

Note: in step 1, The strip_tags (); only replaces the html tag with spaces.

For example:

<P> Zhang zhibin </p> <br/> </p> <p> alsdkjf; laskjd; flasj; </p> <p> asdjfasjd; lkafsj; lfdkj </p> <p> aksdjfl; ak </p>

After strip_tags () is processed, it becomes

Zhang zhibin ZHANG Zhi alsdkjf; laskjd; flasj; asdjfasjd; lkafsj; lfdkj aksdjfl; ak

This may not be what we want. Then we can use the regular expression replacement to remove the blank space.

Final result:

Zhang zhibin ZHANG Zhi alsdkjf; laskjd; flasj; asdjfasjd; lkafsj; lfdkjaksdjfl; ak

In addition, \ s indicates white space characters, and \ S indicates non-white space characters (case sensitive, generally case sensitive indicates the opposite meaning)
