Limiting the output of PHP to 100 characters

Question

Am trying to limit the output of this code <tr><td valign=\"middle\" style=\"font-size:12px; padding-left:10px; padding-bottom:5px; height:10px\">".$postDetails['big_title']."</td></tr>

So it will be from this "blah blah blah blah" to 100 characthers "blah blah.." in UTF8?

Use the function substr to keep at most 100 characters of your string. Example:

<tr><td valign=\"middle\" style=\"font-size:12px; padding-left:10px; padding-bottom:5px; height:10px\">".substr($postDetails['big_title'], 0, 100)."</td></tr>

You can use

substr(strip_tags($postDetails['big_title']), 0, 70);

It will strip out any additional elements within the output.

Just check whether the string exceeds 100 chars, if yes, the use substr and append the ellipsis, if not just leave it as it is. Example:

$big_title = (strlen($postDetails['big_title']) > 100) ? substr($postDetails['big_title'], 0, 100) . '&hellip;' : $postDetails['big_title'];

echo "
    <tr>
        <td 
            valign=\"middle\" 
            style=\"font-size:12px; padding-left:10px; padding-bottom:5px; height:10px\"
        >"
        .$big_title.
        "</td>
    </tr>";

The asker states that he wanted ellipses. I think a custom function would work very nice for this:

function limitOutput($string, $limit){
    if (strlen($string) > $limit){
        $string = substr($string, 0, $limit - 3) . '...';
    }
    return $string;
}

This can be used like so:

<tr><td valign=\"middle\" style=\"font-size:12px; padding-left:10px; padding-bottom:5px;height:10px\">".limitOutput($postDetails['big_title'],100)."</td></tr>

EDIT - Response to it not working:

<?php

function limitOutput($string, $limit){
    if (strlen($string) > $limit){
        $string = substr($string, 0, $limit - 3) . '...';
    }
    return $string;
}

$postDetails['big_title'] = str_repeat('12345678901234567890', 20);

echo $postDetails['big_title'].'<br><br>';

echo "<tr><td valign=\"middle\" style=\"font-size:12px; padding-left:10px; padding-bottom:5px;height:10px\">".limitOutput($postDetails['big_title'],100)."</td></tr>";

@user3590788 I tested it with the code above in my edited answer and it seems to work just fine. — Tim, Aug 30 '14 at 17:23
