"MICROSOFT CORP CIK#: 0000789019 (see all company filings)"

我想在“CORP”位之后切断一切.我将如何在PHP中执行此操作？我习惯了Python,所以我不确定这是怎么做的.

要清楚,这是我想要的输出：

"MICROSOFT CORP"

我在尝试：

$companyname = substr($companyname,strpos($companyname," CIK"));

而我什么也没有显示出来.

这是我的完整代码：

<?PHP
include 'simple_html_dom.PHP';
$htML = file_get_html('http://www.sec.gov/cgi-bin/browse-edgar?company=&amp;match=&CIK=MSFT&filenum=&state=&Country=&SIC=&owner=exclude&Find=Find+Companies&action=getcompany');
$companyname = $html->find('span[class=companyName]',0);
$companyname = substr($companyname," CIK#")+5);
$bizadd = $html->find('div[class="mailer"]');
echo $companyname;
echo "<br />";
foreach ($bizadd as $value) {
    $addvals = $value->find('span[class="mailerAddress"]');
    echo "<br />";
    foreach ($addvals as $value) {
        echo $value;
        echo "<br />";
    }
}
?>
