These do not require loading any libraries or helpers.</p> - -<h2>is_php('<var>version_number</var>')</h2> - -<p>is_php() determines of the PHP version being used is greater than the supplied <var>version_number</var>.</p> - -<code>if (is_php('5.3.0'))<br /> -{<br /> - $str = quoted_printable_encode($str);<br /> -}</code> - -<p>Returns boolean <kbd>TRUE</kbd> if the installed version of PHP is equal to or greater than the supplied version number. Returns <kbd>FALSE</kbd> if the installed version of PHP is lower than the supplied version number.</p> - - -<h2>is_really_writable('<var>path/to/file</var>')</h2> - -<p>is_writable() returns TRUE on Windows servers when you really can't write to the file as the OS reports to PHP as FALSE only if the read-only attribute is marked. This function determines if a file is actually writable by attempting to write to it first. Generally only recommended on platforms where this information may be unreliable.</p> - -<code>if (is_really_writable('file.txt'))<br /> -{<br /> - echo "I could write to this if I wanted to";<br /> -}<br /> -else<br /> -{<br /> - echo "File is not writable";<br /> -}</code> - -<h2>config_item('<var>item_key</var>')</h2> -<p>The <a href="../libraries/config.html">Config library</a> is the preferred way of accessing configuration information, however config_item() can be used to retrieve single keys. See Config library documentation for more information.</p> - -<h2>show_error('<var>message</var>'), show_404('<var>page</var>'), log_message('<var>level</var>', '<samp>message</samp>')</h2> -<p>These are each outlined on the <a href="errors.html">Error Handling</a> page.</p> - -<h2>set_status_header(<var>code</var>, '<var>text</var>');</h2> - -<p>Permits you to manually set a server status header. Example:</p> - -<code>set_status_header(401);<br /> -// Sets the header as: Unauthorized</code> - -<p><a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">See here</a> for a full list of headers.</p> - - -<h2>remove_invisible_characters(<var>$str</var>)</h2> -<p>This function prevents inserting null characters between ascii characters, like Java\0script.</p> - - -<h2>html_escape(<var>$mixed</var>)</h2> -<p>This function provides short cut for htmlspecialchars() function. It accepts string and array. To prevent Cross Site Scripting (XSS), it is very useful.</p> - -</div> - - -<!-- END CONTENT --> - - -<div id="footer"> -<p> -Previous Topic: <a href="autoloader.html">Auto-loading Resources</a><a href="hooks.html"></a> - · -<a href="#top">Top of Page</a> · -<a href="../index.html">User Guide Home</a> · -Next Topic: <a href="routing.html">URI Routing</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>
