将图像插入到html代码变量中

I have a PHP variable like this:

Example1

$data = '<p>This is paragraph.</p>
         <p title="not-special">No!</p>
        ';

Example2

$data = '<p>This is paragraph.</p>
         <p title="special">Yes!</p>
        ';

I want to have a php function, that checks whether there's p element with title="special", and if so, insert div element "YAP!".

How can this be done?

    You can accomplish it in various different ways, a working one could be:

        $data = '<p>This is paragraph.</p>
    <p title="special">Yes!</p>
    ';
    if (strpos($data, 'special') !== false) {
        $data = '<p>This is paragraph.</p>
        <p title="special">Yes!</p>
        <div>YEP</div>
        ';
    }   
    echo $data;
    

    Anyway, this was not the best way to ask a question, please have a look at: How to ask a question

    If there is a special case for formatting in a view, you can specify it easily with a variable.

    <?php
    // Check somewhere for the special case
    $specialCase = $_GET['success'];
    ?>
    
    <p>This is paragraph.</p>
    <p title="special">Yes!</p>
    
    <?php
    // Display the extra div.
    if ($specialCase === 'true') {
        echo '<div class="yap"></div>';
    }
    <?php

    You could use PHP Function to check if the variable contains a certain string, see: http://php.net/manual/de/function.strpos.php
