Xiaobian to share with you whether php can delete html tag content, I hope you have gained something after reading this article, let's discuss it together!

php can delete html tag content, the specific methods are: 1, use php's own function strip_tags to delete all or retain the specified html tag;2, through the strip_html_tags() function to delete the specified html tag and tag content, and so on.

Operating environment: Windows 7 system, PHP 7.1 version, Dell G3 computer.

php delete html tags and tags inside the method

Often dig other people's website articles pit people; I mean the kind of batch collection does not look at the content, and will inevitably use the function to delete html tags; here are three different uses of the method;

$str='

Here's the p tag.

Here's the a-tag.

';

1: Delete all or keep specified html tags

php comes with the function strip_tags can meet the requirements,

strip_tags(string,allow);

string: string to be processed;

allow: the specified label to be retained, multiple labels can be written;

//Output:

Here's the p tag.

Here's the a-tag.

The advantage of the subfunction is simple and rude, but the disadvantage is also obvious; if there are a lot of labels; and I just want to delete a specified one; then write a lot of labels that need to be preserved; so there is a second method;

2: Delete the specified html tag

strip_html_tags($tags,$str);

$tags: tags to delete (array format)

$str: string to be processed;

//output here is p label here is a label

;

3: Delete labels and label content

strip_html_tags($tags,$str);

$tags: tags to delete (array format)

$str: string to be processed;

//Output

Here's the p tag.

;

Many website articles will bring website names and links, such as Bai Junyao blog; this function is exclusive to this; do not take this function collection site ah; otherwise guarantee not to kill you;

4: Ultimate function, delete the specified label; delete or retain the contents of the label;

strip_html_tags($tags,$str,$content);

$tags: tags to delete (array format)

$str: string to be processed;

$content: Delete the content in the tag 0 Keep the content 1 Do not keep the content

//Output

Here's the p tag.
