substr PHP shorten lengh of a string (WordPress Plugin)

Question

I am a novice at PHP I am just learning. But I have come across a problem that I am having real trouble with.

I am working inside WordPress with a plug-in and I am trying to shorten a string within that plug-in so it just displays a small amount of text instead of a large section.

I know from reading this website and other including PHP.net that I need to use 'substr' The main problem is I think I need to add more than the string.

In my working one that does not shorten there is something with the string in ['post_content'] I am not sure how that works with the syntax of PHP.

This is what I have come up with using the resources I found. Also adding ... to the end would be great.

<?php

if (strlen($property) > 15) // if you want...
{
    $maxLength = 14;
    $property = substr($property, 0, $maxLength);
}
?>

And this is the working but without shortening

<?php echo $property['post_content']; ?>

Resources

Get first n characters of a string

Shorten a text string in PHP

Shorten string with a "..." body

To me it is not clear what you are asking. Maybe you can make your question clearer. However, you may want to have a look at mb_substr() as well. — , Apr 02 '15 at 10:28

<?php
$property = $property['post_content'];
if (strlen($property) > 15) // if you want...
{
    $maxLength = 14;
    $property = substr($property, 0, $maxLength);
}
echo $property;
?>

What if he still wants to use `$property['post_content']` or other items of the `$property` array ? – Kamran Apr 02 '15 at 10:33

On very 1st line he can declare another variable $postContent = $property['post_content'] and use it :) – Muhammad Ahmed Apr 02 '15 at 10:35
or store whole array in another variable in start if he need it again. – Muhammad Ahmed Apr 02 '15 at 10:37

Try this

$property = (strlen($property) > 15) ? substr($property,0,14): $property ;
