Php htmlentities () function

Write your php code

(PHP 3, PHP 4 , PHP 5)

htmlentities -- Convert all applicable characters to HTML entities

Syntax

string htmlentities ( string string [, int quote_style [, string charset]] )

This function is identical to htmlspecialchars() in all ways, except with htmlentities(), all characters which have HTML character entity equivalents are translated into these entities.

Like htmlspecialchars(), the optional second quote_style parameter lets you define what will be done with 'single' and "double" quotes. It takes on one of three constants with the default being ENT_COMPAT:

Table 1. Available quote_style constants

Constant Name	Syntax
`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.

Support for the optional quote parameter was added in PHP 4.0.3.

Like htmlspecialchars(), it takes an optional third argument charset which defines character set used in conversion. Support for this argument was added in PHP 4.1.0. Presently, the ISO-8859-1 character set is used as the default.

Following character sets are supported in PHP 4.3.0 and later.

Table 2. Supported charsets

Charset	Aliases	Syntax
ISO-8859-1	ISO8859-1	Western European, Latin-1
ISO-8859-15	ISO8859-15	Western European, Latin-9. Adds the Euro sign, French and Finnish letters missing in Latin-1(ISO-8859-1).
UTF-8		ASCII compatible multi-byte 8-bit Unicode.
cp866	ibm866, 866	DOS-specific Cyrillic charset. This charset is supported in 4.3.2.
cp1251	Windows-1251, win-1251, 1251	Windows-specific Cyrillic charset. This charset is supported in 4.3.2.
cp1252	Windows-1252, 1252	Windows specific charset for Western European.
KOI8-R	koi8-ru, koi8r	Russian. This charset is supported in 4.3.2.
BIG5	950	Traditional Chinese, mainly used in Taiwan.
GB2312	936	Simplified Chinese, national standard character set.
BIG5-HKSCS		Big5 with Hong Kong extensions, Traditional Chinese.
Shift_JIS	SJIS, 932	Japanese
EUC-JP	EUCJP	Japanese

Note: Any other character sets are not recognized and ISO-8859-1 will be used instead.

If you're wanting to decode instead (the reverse) you can use html_entity_decode().

Example 1. A htmlentities() example


<?php
$str = "A 'quote' is <b>bold</b>";

// Outputs: A 'quote' is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str);

// Outputs: A &#039;quote&#039; is &lt;b&gt;bold&lt;/b&gt;
echo htmlentities($str, ENT_QUOTES);
?>
