Example:</p> - -<code> -$string = "Here is a nice text string consisting of eleven words.";<br /> -<br /> -$string = word_limiter($string, 4);<br /><br /> - -// Returns: Here is a nice… -</code> - -<p>The third parameter is an optional suffix added to the string. By default it adds an ellipsis.</p> - - -<h2>character_limiter()</h2> - -<p>Truncates a string to the number of <strong>characters</strong> specified. It maintains the integrity -of words so the character count may be slightly more or less then what you specify. Example:</p> - -<code> -$string = "Here is a nice text string consisting of eleven words.";<br /> -<br /> -$string = character_limiter($string, 20);<br /><br /> - -// Returns: Here is a nice text string… -</code> - -<p>The third parameter is an optional suffix added to the string, if undeclared this helper uses an ellipsis.</p> - - - -<h2>ascii_to_entities()</h2> - -<p>Converts ASCII values to character entities, including high ASCII and MS Word characters that can cause problems when used in a web page, -so that they can be shown consistently regardless of browser settings or stored reliably in a database. -There is some dependence on your server's supported character sets, so it may not be 100% reliable in all cases, but for the most -part it should correctly identify characters outside the normal range (like accented characters). Example:</p> - -<code>$string = ascii_to_entities($string);</code> - - -<h2>entities_to_ascii()</h2> - -<p>This function does the opposite of the previous one; it turns character entities back into ASCII.</p> - -<h2>convert_accented_characters()</h2> - -<p>Transliterates high ASCII characters to low ASCII equivalents, useful when non-English characters need to be used where only standard ASCII characters are safely used, for instance, in URLs.</p> - -<code>$string = convert_accented_characters($string);</code> - -<p>This function uses a companion config file <dfn>application/config/foreign_chars.php</dfn> to define the to and from array for transliteration.</p> - -<h2>word_censor()</h2> - -<p>Enables you to censor words within a text string. The first parameter will contain the original string. The -second will contain an array of words which you disallow. The third (optional) parameter can contain a replacement value -for the words. If not specified they are replaced with pound signs: ####. Example:</p> - -<code> -$disallowed = array('darn', 'shucks', 'golly', 'phooey');<br /> -<br /> -$string = word_censor($string, $disallowed, 'Beep!');</code> - - -<h2>highlight_code()</h2> - -<p>Colorizes a string of code (PHP, HTML, etc.). Example:</p> - -<code>$string = highlight_code($string);</code> - -<p>The function uses PHP's highlight_string() function, so the colors used are the ones specified in your php.ini file.</p> - - -<h2>highlight_phrase()</h2> - -<p>Will highlight a phrase within a text string. The first parameter will contain the original string, the second will -contain the phrase you wish to highlight. The third and fourth parameters will contain the opening/closing HTML tags -you would like the phrase wrapped in. Example:</p> - -<code> -$string = "Here is a nice text string about nothing in particular.";<br /> -<br /> -$string = highlight_phrase($string, "nice text", '<span style="color:#990000">', '</span>'); -</code> - -<p>The above text returns:</p> - -<p>Here is a <span style="color:#990000">nice text</span> string about nothing in particular.</p> - - - -<h2>word_wrap()</h2> - -<p>Wraps text at the specified <strong>character</strong> count while maintaining complete words. Example:</p> - -<code>$string = "Here is a simple string of text that will help us demonstrate this function.";<br /> -<br /> -echo word_wrap($string, 25);<br /> -<br /> -// Would produce:<br /> -<br /> -Here is a simple string<br /> -of text that will help<br /> -us demonstrate this<br /> -function</code> - -<h2>ellipsize()</h2> - -<p>This function will strip tags from a string, split it at a defined maximum length, and insert an ellipsis.</p> -<p>The first parameter is the string to ellipsize, the second is the number of characters in the final string. The third parameter is where in the string the ellipsis should appear from 0 - 1, left to right. For example. a value of 1 will place the ellipsis at the right of the string, .5 in the middle, and 0 at the left.</p> -<p>An optional forth parameter is the kind of ellipsis. By default, <samp>&hellip;</samp> will be inserted.</p> - -<code>$str = 'this_string_is_entirely_too_long_and_might_break_my_design.jpg';<br /> -<br /> -echo ellipsize($str, 32, .5);</code> - -Produces: - -<code>this_string_is_e…ak_my_design.jpg</code> - - -</div> -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="string_helper.html">String Helper</a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="typography_helper.html">Typography Helper</a> -</p> -<p><a href="http://codeigniter.com">CodeIgniter</a> · Copyright © 2006 - 2011 · <a href="http://ellislab.com/">EllisLab, Inc.</a></p> -</div> - -</body> -</html>
