PHP uses the DOMDocument class to generate HTML instances (including common tag elements) _ PHP Tutorial

PHP uses the DOMDocument class to generate HTML instances (including common tag elements ). In this section, we will learn how to use core PHP to generate HTML files. recently, when I was querying php.net, I found the DOMDocument class very interesting, in this section, we can learn how to use core PHP to generate HTML files.

Recently, when I was querying php.net, I found that the DOMDocument class is very interesting and can be used to generate XML or HTML files, DOMDocument provides us with a series of methods to generate XML/HTML tags and insert them into the DOM. now let's look at how to generate

Here, let's take a look at the effect generated using the method provided by it. for details, see:

1. create a new DOM file

The code is as follows:

// Instantiate the DOMDocument class and specify the version number
$ Dom = new DOMDocument ('1. 0 ');

// Output the generated tag or code to the page
Echo $ dom-> saveHTML ();

2. add new HTML elements to the DOM file

The code is as follows:

$ Css_text = 'p {color: # ff00ff ;}';

// Create a new style label and CSS content
$ Style = $ dom-> createElement ('style', $ css_text );

// Add the style label to the DOM file
$ Dom-> appendChild ($ style );

// The output result is as follows:

Here we need to talk about the createElement method. when you want to create

The code is as follows:

$ P_text = 'This is a paragraph .';

// Create a new p tag and content
$ P = $ dom-> createElement ('P', $ p_text );

// Create a new property 'id'
$ Domattriattribute = $ dom-> createAttribute ('id ');

// Add a value for the property 'id'
$ DomAttribute-> value = 'description ';

// Add this property to the p tag
$ P-> appendChild ($ domattrichild );

// Add the p tag to the DOM file
$ Dom-> appendChild ($ p );

// The output result is as follows:

One day

4. Add Form elements

Add textbox

The code is as follows:

$ Input = $ dom-> createElement ('input ');

$ Domattriattribute = $ dom-> createAttribute ('type ');
$ DomAttribute-> value = 'text ';
$ Input-> appendChild ($ domattrichild );

$ Domattriattribute = $ dom-> createAttribute ('name ');
$ DomAttribute-> value = 'e-mail ';
$ Input-> appendChild ($ domattrichild );

$ Dom-> appendChild ($ input );

// The output result is as follows:

5. create a Table

The code is as follows:

$ Table = $ dom-> createElement ('table ');

$ Domattriattribute = $ dom-> createAttribute ('id ');
$ DomAttribute-> value = 'My _ table ';

$ Tr = $ dom-> createElement ('tr ');
$ Table-> appendChild ($ tr );

$ Td = $ dom-> createElement ('TD ', 'label ');
$ Tr-> appendChild ($ td );

$ Td = $ dom-> createElement ('TD ', 'value ');
$ Tr-> appendChild ($ td );

$ Table-> appendChild ($ domattrichild );

$ Dom-> appendChild ($ table );

// The output result is as follows:

Label

Value

Finally, let's get Complete and complex example:

The code is as follows:

$ Dom = new DOMDocument ('1. 0 ');

// CSS content
$ Css_text = '';
$ Css_text. = 'body {width: 285px; margin: auto; margin-top: 50px ;}';
$ Css_text. = '# my_table {border: 1px solid # ececec ;}';
$ Css_text. = '# my_table th {border: 1px solid # ececec; padding: 5px; text-decoration: underline ;}';
$ Css_text. = '# my_table td {border: 1px solid # ececec; padding: 5px ;}';
$ Css_text. = '# my_table td: first-child {text-align: right; color: #333333; font-weight: bold; color: #999999 ;}';

// Create a new style label and CSS content
$ Style = $ dom-> createElement ('style', $ css_text );

// Create a new property 'type'
$ Domattriattribute = $ dom-> createAttribute ('type ');

// Add a value for the attribute 'type'
$ DomAttribute-> value = 'text/css ';

// Add this attribute to the style label
$ Style-> appendChild ($ domattrichild );

// Add the style label to the DOM file
$ Dom-> appendChild ($ style );

// Add form
$ Form = $ dom-> createElement ('form ');
$ Dom-> appendChild ($ form );
$ Formattriattribute = $ dom-> createAttribute ('method ');
$ FormAttribute-> value = 'post ';
$ Form-> appendChild ($ formattrichild );

// Add a table
$ Table = $ dom-> createElement ('table ');
$ TableAttribute = $ dom-> createAttribute ('id ');
$ TableAttribute-> value = 'My _ table ';
$ Table-> appendChild ($ tableAttribute );

// Add a new row)
$ Tr = $ dom-> createElement ('tr ');
$ Table-> appendChild ($ tr );

// Add a new column)
$ Th = $ dom-> createElement ('th', 'generate HTML using php ');
$ Tr-> appendChild ($ th );
$ ThAttribute = $ dom-> createAttribute ('colspan ');
$ ThAttribute-> value = '2 ';
$ Th-> appendChild ($ thAttribute );

// Add a new row)
$ Tr = $ dom-> createElement ('tr ');
$ Table-> appendChild ($ tr );

$ Domattriattribute = $ dom-> createAttribute ('value ');
$ Domattrie-> value = 'male ';
$ Opt-> appendChild ($ domattrichild );
$ Select-> appendChild ($ opt );

$ Opt = $ dom-> createElement ('option', 'female ');
$ Domattriattribute = $ dom-> createAttribute ('value ');
$ Domattriale-> value = 'female ';
$ Opt-> appendChild ($ domattrichild );
$ Select-> appendChild ($ opt );

// Add a new row)

// Add the input element to the column
$ Radio = $ dom-> createElement ('input ');
$ Td-> appendChild ($ radio );
$ Radattriattribute = $ dom-> createAttribute ('type ');
$ RadAttribute-> value = 'Radio ';
$ Radio-> appendChild ($ radattrichild );
$ Radattriattribute = $ dom-> createAttribute ('name ');
$ Radattriest-> value = 'interest ';
$ Radio-> appendChild ($ radattrichild );
$ Radattriattribute = $ dom-> createAttribute ('id ');
$ RadAttribute-> value = 'php ';
$ Radio-> appendChild ($ radattrichild );

$ Label = $ dom-> createElement ('label', 'php ');
$ LabelAttribute = $ dom-> createAttribute ('');
$ LabelAttribute-> value = 'php ';
$ Label-> appendChild ($ labelAttribute );
$ Td-> appendChild ($ label );

$ Radio = $ dom-> createElement ('input ');
$ Td-> appendChild ($ radio );
$ Radattriattribute = $ dom-> createAttribute ('type ');
$ RadAttribute-> value = 'Radio ';
$ Radio-> appendChild ($ radattrichild );
$ Radattriattribute = $ dom-> createAttribute ('name ');
$ Radattriest-> value = 'interest ';
$ Radio-> appendChild ($ radattrichild );
$ Radattriattribute = $ dom-> createAttribute ('id ');
$ RadAttribute-> value = 'jquery ';
$ Radio-> appendChild ($ radattrichild );

$ LabelAttribute-> value = 'jquery ';
$ Label-> appendChild ($ labelAttribute );
$ Td-> appendChild ($ label );

$ Input-> appendChild ($ tdattrichild );

// Add table to form
$ Form-> appendChild ($ table );

Echo $ dom-> saveHTML ();

Finally, let's take a look at how to use core PHP to generate HTML files. recently, when I was querying php.net, I found the DOMDocument class very interesting...
