не удается разделить строку, проанализированную с веб-страницы?

@user1518659 user1518659 попробуйте это, чтобы решить проблему, просто замените   пробелом перед переходом к DOMDocument, я также добавил разделение имени и фамилии :) надеюсь, это поможет.

<?php 
header('Content-Type: text/html; charset=utf-8'); //Required if your outputting, as the description contains utf-8 characters
//Load the source (input)
$html_source = file_get_contents('http://www.reuters.com/finance/stocks/companyOfficers?symbol=AOS');
$html_source = str_replace('&nbsp;',' ',$html_source);

//Dom document
$dom = new DOMDocument('1.0');
@$dom->loadHTML($html_source);

$out =array();
$i=0;
foreach($dom->getElementsByTagName('table') as $table) {
    if($table->getAttribute('class')=='dataTable'){

        foreach($table->getElementsByTagName('tr') as $tr){
            if(isset($tr->getElementsByTagName('td')->item(0)->nodeValue)){

                $out[$i]['fullname'] = $tr->getElementsByTagName('td')->item(0)->nodeValue;

                $name = explode(' ',$out[$i]['fullname']);
                $out[$i]['first_name'] = $name[0];
                $out[$i]['last_name'] = $name[1];

                if(!isset($tr->getElementsByTagName('td')->item(2)->nodeValue)){

                    foreach ($out as $key=>$value){
                        if($value['fullname'] == $tr->getElementsByTagName('td')->item(0)->nodeValue &&
                        !is_numeric(substr($tr->getElementsByTagName('td')->item(1)->nodeValue,0,1)) && 
                        $tr->getElementsByTagName('td')->item(1)->nodeValue != "--" ){
                            $out[$key]['description']= $tr->getElementsByTagName('td')->item(1)->nodeValue;
                        }
                    }

                }else{
                    if(!isset($tr->getElementsByTagName('td')->item(2)->nodeValue)){continue;}
                    if(isset($tr->getElementsByTagName('td')->item(3)->nodeValue)){
                        $out[$i]['age']= $tr->getElementsByTagName('td')->item(1)->nodeValue;
                        $out[$i]['since']= $tr->getElementsByTagName('td')->item(2)->nodeValue;
                        $out[$i]['position']= $tr->getElementsByTagName('td')->item(3)->nodeValue;
                    }
                }
                $i++;
            }
        }
    }
}

//Clean up
$return = array();
foreach ($out as $key=>$row){
    if(isset($row['fullname']) && isset($row['age']) && isset($row['since']) && isset($row['position']) && isset($row['description'])){
        $return[$key] = $out[$key];
    }
}


print_r($return);

Попробуйте решить проблему  :

explode(chr(0xC2).chr(0xA0), $str)

Неразрывный пробел существует в UTF-8 из двух байтов: 0xC2 и 0xA0.

Ссылка - Проблема синтаксического анализа PHP - и

Сущность неразрывного пробела, которая у вас есть, сломана. Должно быть  . Обратите внимание на точку с запятой.

Чтобы ответить на ваш вопрос, вы можете просто сделать:

var_dump(explode('&nbsp', $out[$i]['name']));

Или, если сущность фиксирована:

var_dump(explode(' ', $out[$i]['name']));

Это должно сделать это

<?php

$a = preg_split( "/[\s]|[&nbsp;]|[ ]/", $out[$i]['name'] ); //$a is an array with keys: Mark, Smith

explode() позволяет только один разделитель разделить строку/массив, в то время как preg_split() используется для множества разделителей
