Question

我是初学者，在php中，我想在我发现的第一个空格后使用正则表达式删除字符串。我的代码就像：

<?php

   $barcode = $_POST['barcode'];
   $adress = "https://...";
   $timeout = 40;
   $ch = curl_init($adress);
   curl_setopt($ch, CURLOPT_FRESH_CONNECT, true); 
   curl_setopt($ch, CURLOPT_TIMEOUT, $timeout); 
   curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 

    if (strpos($adress, 'https://') === 0) {
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
    }

    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

    $page_content = curl_exec($ch); 
    $dom = new \DOMDocument('1.0', 'UTF-8');
    $internalErrors = libxml_use_internal_errors(true);

    $node = $dom->loadHTML($page_content);
    $listeImages = $dom->getElementsByTagName('img');
    foreach ($listeImages as $image)
    {
        $link = $dom->createElement("a");
        $href = $dom->createAttribute('srcset');
        $href->value = $image->getAttribute('srcset');
        $value_img = print( $href -> nodeValue.'<br />');
        $image->parentNode->replaceChild($link, $image);
        $link->appendChild($href);

        /*$exclusion_space_url=array(' ', ' 1x');
        $url_cleaned=$this->$value_img;
        foreach ($exclusion_space_url as $key=>$value) {
        $url_cleaned=str_replace($value," ",$url_cleaned);*/ ***what i tried to do***
        }     
    }

   curl_close($ch);
?>

结果是：

一个html页面，其中有3-4行url serparate with space

感谢您的帮助
