getting all values from h1 tags using php

Viewed 107 times

I want to receive an array that contains all the h1 tag values from a text

Example, if this where the given input string:

<h1>hello</h1>
<p>random text</p>
<h1>title number two!</h1>

I need to receive an array containing this:

titles[0] = 'hello',
titles[1] = 'title number two!'

I already figured out how to get the first h1 value of the string but I need all the values of all the h1 tags in the given string.

I'm currently using this to receive the first tag:

function getTextBetweenTags($string, $tagname) 
 {
  $pattern = "/<$tagname ?.*>(.*)</$tagname>/";
  preg_match($pattern, $string, $matches);
  return $matches[1];
 }

I pass it the string I want to be parsed and as $tagname I put in "h1". I didn't write it myself though, I've been trying to edit the code to do what I want it to but nothing really works.

I was hoping someone could help me out.

Thanks in advance.

you could use simplehtmldom:

function getTextBetweenTags($string, $tagname) {
    // Create DOM from string
    $html = str_get_html($string);

    $titles = array();
    // Find all tags 
    foreach($html->find($tagname) as $element) {
        $titles[] = $element->plaintext;
    }
}

<form name="add" method="post">
     <p>Age:</p>
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     </select>
     <input type="submit" name="submit"/>
</form>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

The usual workflow:

Provide a Javascript rich-text editor for your users such as TinyMCE: http://tinymce.moxiecode.com/
Grab the source generated by the RTE and filter it through HTML Purifier before saving to the database.
Escape the existing HTML: <div id="myHtml" style="display: none"><?php echo htmlentities($html); ?></div>
Re-populate the RTE via Javascript - in the case of TinyMCE as follows: tinyMCE.activeEditor.setContent($('#myHtml').html());

You can also load the HTML content via AJAX.

SELECT userID, userName, userProfession, userPic FROM tbl_users WHERE userProfession = "Teacher" ORDER BY userID DESC

is what you need.

Note that this answer is outdated! The mysql extension is no longer available out of the box as of PHP7. If you want to use the old mysql functions in PHP7, you will have to compile ext/mysql from PECL. See the other answers for more current solutions.

This would work, see more documentation here : http://php.net/manual/en/function.mysql-fetch-array.php

$result = mysql_query("SELECT names FROM Customers");
$storeArray = Array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    $storeArray[] =  $row['names'];  
}
// now $storeArray will have all the names.
