Additional flags for specifying the used doctype:

«;

Php echo(html_entity_decode($user));

This tutorials show you how to use html_entity_decode.

html_entity_decode is used in the following way.

echo(html_entity_decode($user)); More precisely, this function decodes all the entities (including all numeric entities) that a) are necessarily valid for the chosen document type ' i.e., for XML, this function does not decode named entities that might be defined in some DTD ' and b) whose character or characters are in the coded character set associated with the chosen encoding and are permitted in the chosen document type. All other entities are left as is.

The html_entity_decode is declared as follows:

html_entity_decode( string $string, int $flags = ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401, ?string $encoding = null): string 

The return value is Returns the decoded string.

Examples

// w w w . d em o 2 s . c o m /* if ($_FILES["file"]["error"] > 0) < echo "Error: " . $_FILES["file"]["error"] . "
"; > else < echo "Upload: " . $_FILES["file"]["name"] . "
"; echo "Type: " . $_FILES["file"]["type"] . "
"; echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb
"; echo "Stored in: " . $_FILES["file"]["tmp_name"]; > */ //d?but analyse du fichier // Read the file into an array $myfile=$_FILES["file"]["tmp_name"]; // Read the file into an array $users = file($myfile); foreach ($users as $user) < /* list($name)=explode(";",$line); print($name."\n");*/ echo(html_entity_decode($user)); > //echo var_dump($_FILES); ?>

Convert HTML Entities and Special Characters

Learn how to encode or decode all or special HTML characters within a string.

htmlspecialchars()

1. $string – The input string.
2. $flags – A bitmask of one or more flags.
3. $encoding – The default is UTF-8 character set. To use a different character set, pass the character set, for example, BIG5 .
4. $double_encode – If false PHP will not encode existing HTML entities in the string, the default is true to convert everything.

If you want to display HTML coding on a web page, you should convert the HTML special characters to HTML entities. The htmlspecialchars() function converts the following characters to their HTML entities. This results in the characters being displayed exactly as entered, rather than parsed and rendered by the browser as if they were actual HTML.

• & (ampersand) converts to &
• ‘ (single quote) converts to '
• » (double quote) converts to "
• < (less than) converts to <
• > (greater than) converts to >

See the following example:

Note: Use the ENT_QUOTES flag to escape both single and double quotes into HTML entities.

htmlspecialchars_decode()

 echo htmlspecialchars_decode (' " '); // " echo htmlspecialchars_decode (' ' '); // ' echo htmlspecialchars_decode (' ' ', ENT_QUOTES); // ';

htmlentities()

1. $string – The input string.
2. $flags – A bitmask of one or more flags.
3. $encoding – The default is UTF-8 character set. To use a different character set, pass the character set, for example, BIG5 .
4. $double_encode – If false PHP will not encode existing HTML entities in the string, the default is true to convert everything.

This htmlentities() function is helpful if you need to convert every character with a special meaning in HTML coding. For example, the copyright symbol © , the cent sign ¢ , or the grave accent è . See the following example:

html_entity_decode()

Using this function you can reverse the effect of the htmlentities() function. For example, the © coverts to copyright symbol © , the ¢ converts to cent sign ¢ , or the è coverts to grave accent è . See the following example:

 echo html_entity_decode (' " '); // " echo html_entity_decode (' ' '); // ' echo html_entity_decode (' ' ', ENT_QUOTES); // ';

Flags

The above functions use a bitmask of one or more flags, which specify how to handle quotes, invalid code unit sequences, and the used document type. The default is ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401 .

• ENT_COMPAT – Converts only double-quotes.
• ENT_QUOTES – Converts both single and double quotes.
• ENT_NOQUOTES – Doesn’t convert either single or double quotes.
• ENT_IGNORE – Doesn’t convert anything.
• ENT_SUBSTITUTE – Replaces invalid code with Unicode replacement characters instead of returning an empty string.
• ENT_DISALLOWED – Replaces invalid code with Unicode replacement characters instead of leaving them as is.
• ENT_HTML401 – Handles the code as HTML version 4.01.
• ENT_XML1 – Handles the code as XML version 1.
• ENT_XHTML – Handles the code as XHTML.
• ENT_HTML5 – Handles the code as HTML5.

Double encoding

By default, htmlspecialchars() , htmlspecialchars_decode() , htmlentities() , and html_entity_decode() functions double encode existing character entities. As a result, & is converted to &amp; and " is converted to &quot; . You can use the double_encode named argument to turn off this default behavior, see the following example:

html_entity_decode

html_entity_decode() is the opposite of htmlentities() in that it converts HTML entities in the string to their corresponding characters.

More precisely, this function decodes all the entities (including all numeric entities) that a) are necessarily valid for the chosen document type — i.e., for XML, this function does not decode named entities that might be defined in some DTD — and b) whose character or characters are in the coded character set associated with the chosen encoding and are permitted in the chosen document type. All other entities are left as is.

Parameters

A bitmask of one or more of the following flags, which specify how to handle quotes and which document type to use. The default is ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401 .

Available flags constants

Constant Name	Description
ENT_COMPAT	Will convert double-quotes and leave single-quotes alone.
ENT_QUOTES	Will convert both double and single quotes.
ENT_NOQUOTES	Will leave both double and single quotes unconverted.
ENT_SUBSTITUTE	Replace invalid code unit sequences with a Unicode Replacement Character U+FFFD (UTF-8) or � (otherwise) instead of returning an empty string.
ENT_HTML401	Handle code as HTML 4.01.
ENT_XML1	Handle code as XML 1.
ENT_XHTML	Handle code as XHTML.
ENT_HTML5	Handle code as HTML 5.

An optional argument defining the encoding used when converting characters.

If omitted, encoding defaults to the value of the default_charset configuration option.

Although this argument is technically optional, you are highly encouraged to specify the correct value for your code if the default_charset configuration option may be set incorrectly for the given input.

The following character sets are supported:

Supported charsets

Charset	Aliases	Description

MacRoman	Charset that was used by Mac OS.
»	An empty string activates detection from script encoding (Zend multibyte), default_charset and current locale (see nl_langinfo() and setlocale() ), in this order. Not recommended.

Note: Any other character sets are not recognized. The default encoding will be used instead and a warning will be emitted.

Returns the decoded string.
