php - Get string length of each element in an array

I'm trying to set the max length of each post on a site, but strlen() doesn't work with arrays. So I need to break it down to check each post in the array.

How could I adapt what I have to get this if statment to work correctly. The issue is the strlen() not accepting object.

    for($i = 0, $size = count($somePosts); $i < $size; ++$i) {
        if (strlen(utf8_decode($somePosts[$i])) > $max_length) {
            $offset = ($max_length - 3) - strlen($somePosts);
            $somePosts = substr($somePosts, 0, strrpos($reviewPosts, ' ', $offset)) . '...';
        }
    }

I'm using Doctrine to generate the array, which works fine.

Thanks.

Edit:

Error - Warning: strlen() expects parameter 1 to be string, object given

Edit 2:

No error messages now, but the code doesn't work in terms of limiting the length of the posts.

As alternative you can use array_map

<?php

$strs = array('abcdefgh', 'defghjklmn', 'ghjefggezgzgezg');
$max = 5;
$strs = array_map(function($val) use ($max) {
    if (strlen($val.'') < $max) return $val.'';
    return substr($val.'', 0,$max-3).'...';
},$strs);

var_dump($strs);

EDIT implicit casts added to cast object to string

You need to access the current array item like $somePosts[$i] and not $somePosts

for($i = 0, $size = count($somePosts); $i < $size; ++$i) {
    if (strlen(utf8_decode($somePosts[$i])) > $max_length) {
        $offset = ($max_length - 3) - strlen($somePosts[$i]);
        $somePosts[$i] = substr($somePosts[$i], 0, strrpos($reviewPosts, ' ', $offset)) . '...';
    }
}
