-<h1>String Helper</h1>
-
-<p>The String Helper file contains functions that assist in working with strings.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('string');</code>
-
-<p>The following functions are available:</p>
-
-<h2>random_string()</h2>
-
-<p>Generates a random string based on the type and length you specify. Useful for creating passwords or generating random hashes.</p>
-
-<p>The first parameter specifies the type of string, the second parameter specifies the length. The following choices are available:</p>
-
-
-<ul>
-<li><strong>alnum</strong>: Alpha-numeric string with lower and uppercase characters.</li>
-<li><strong>numeric</strong>: Numeric string.</li>
-<li><strong>nozero</strong>: Numeric string with no zeros.</li>
-<li><strong>unique</strong>: Encrypted with MD5 and uniqid(). Note: The length parameter is not available for this type.
-Returns a fixed length 32 character string.</li>
-</ul>
-
-<p>Usage example:</p>
-
-<code>echo random_string('alnum', 16);</code>
-
-
-<h2>alternator()</h2>
-
-<p>Allows two or more items to be alternated between, when cycling through a loop. Example:</p>
-
-<code>for ($i = 0; $i < 10; $i++)<br />
-{<br />
- echo alternator('string one', 'string two');<br />
-}<br />
-</code>
-
-<p>You can add as many parameters as you want, and with each iteration of your loop the next item will be returned.</p>
-
-<code>for ($i = 0; $i < 10; $i++)<br />
-{<br />
- echo alternator('one', 'two', 'three', 'four', 'five');<br />
-}<br />
-</code>
-
-<p><strong>Note:</strong> To use multiple separate calls to this function simply call the function with no arguments to re-initialize.</p>
-
-
-
-<h2>repeater()</h2>
-<p>Generates repeating copies of the data you submit. Example:</p>
-<code>$string = "\n";<br />
-echo repeater($string, 30);</code>
-
-<p>The above would generate 30 newlines.</p>
-<h2>reduce_double_slashes()</h2>
-<p>Converts double slashes in a string to a single slash, except those found in http://. Example: </p>
-<code>$string = "http://example.com//index.php";<br />
-echo reduce_double_slashes($string); // results in "http://example.com/index.php"</code>
-<h2>trim_slashes()</h2>
-<p>Removes any leading/trailing slashes from a string. Example:<br />
- <br />
- <code>$string = "/this/that/theother/";<br />
-echo trim_slashes($string); // results in this/that/theother</code></p>
-
-
-<h2>reduce_multiples()</h2>
-<p>Reduces multiple instances of a particular character occuring directly after each other. Example:</p>
-<code>
-$string="Fred, Bill,, Joe, Jimmy";<br />
-$string=reduce_multiples($string,","); //results in "Fred, Bill, Joe, Jimmy"
-</code>
-<p>The function accepts the following parameters:
-<code>reduce_multiples(string: text to search in, string: character to reduce, boolean: whether to remove the character from the front and end of the string)</code>
-
-The first parameter contains the string in which you want to reduce the multiplies. The second parameter contains the character you want to have reduced.
-The third parameter is FALSE by default; if set to TRUE it will remove occurences of the character at the beginning and the end of the string. Example:
-
-<code>
-$string=",Fred, Bill,, Joe, Jimmy,";<br />
-$string=reduce_multiples($string, ", ", TRUE); //results in "Fred, Bill, Joe, Jimmy"
-</code>
-</p>
-
-<h2>quotes_to_entities()</h2>
-<p>Converts single and double quotes in a string to the corresponding HTML entities. Example:</p>
-<code>$string="Joe's \"dinner\"";<br />
-$string=quotes_to_entities($string); //results in "Joe&#39;s &quot;dinner&quot;"
-</code>
-
-<h2>strip_quotes()</h2>
-<p>Removes single and double quotes from a string. Example:</p>
-<code>$string="Joe's \"dinner\"";<br />
-$string=strip_quotes($string); //results in "Joes dinner"
-</code>
