The target PHP file then accesses the data passed by the form through PHP's $_POST or $_GET variables, depending on the value of the method attribute used in the form. Here is a basic form handler PHP script that will display the contents of the first_name input field on the page: form.html
In HTML and XML, a numeric character reference refers to a character by its Universal Coded Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
Some document formats, such as HTML, PostScript and Rich Text Format have their own 7-bit encoding schemes for non-ASCII characters and can thus be sent without using any special email encodings. E.g. HTML email can use HTML entities to use characters from anywhere in Unicode even if the HTML source text for the email is in a legacy encoding (e ...
In PHP, it is used just before an expression to make the interpreter suppress errors that would be generated from that expression. [33] In Python 2.4 and up, it is used to decorate a function (wrap the function in another one at creation time).

Of course, when a name exists, a named reference (e.g., — for an em dash) is usually more convenient (and more easily recognized) than either numerical code. HTML character names (and the corresponding hexadecimal and decimal codes) are given in List of XML and HTML character entity references.
Special characters can often be displayed using numeric character references or character entity references. See Character encodings in HTML for more information. For example, À and À both render À (A-grave). Percent-encoding can't be used, as it works only in URLs.
