Question

I’m having trouble using strpos correctly. if I search for<br /> it will find it. If I search for <br /><br /><br /> with or without space between, it won’t and using htmlspecialchars I can tell the string is full of it.

   <?php
   $picArray = glob('projectData/' . $data['folder'] . '/*.jpg',GLOB_BRACE);

    $text = nl2br($data['definition']).'<br />';

    $cutP = 0;
    foreach($picArray AS $insert) {

        if(strpos($text,'<br /> <br /> <br />',$cutP) !== FALSE){
            $cutP = strpos($text,'<br /> <br /> <br />',$cutP)+6;
            echo $cutP.'_';
            $str_to_insert = '<img class="inTextImg" title="int" src="'.$insert.'" />';
            $text = substr($text, 0, $cutP) . $str_to_insert . substr($text, $cutP);
        }
        else {
            echo 'haha';
            $text .= '<img class="inTextImg" title="outText!" src="'.$insert.'" />';
        }
    }
    ?>

Thank your for your ideas.

This is because nl2br keeps the original line break characters in place, just after the '<br />'. You need to include the line break characters in the string to search for. Since there can be a few different patterns for this it’s easiest to use a regexp to match it:

$text = preg_replace('/(?:<br \/>\r?\n?){3}/', $str_to_insert, $text);
