Php 从输出中删除空白行

我有一个为谷歌购物创建XML文档的代码。谷歌被挂在一个空行上。我不知道如何把线去掉。代码来自Magento Commerce数据库

新的
有现货的
你可以试着像这样去掉新词

<description><?php echo str_replace(array("\r\n", "\n"), ' ', $row['short_description']); ?></description>



请参阅PHP手册中的函数。
您可以尝试此函数

function removeSpaces($buffer){
    $buffer = str_replace(array('\n', '\r'), array('', ''), $data);
    return $buffer;
}

@ob_start("ob_gzhandler");
@ob_start("removeSpaces");

把它放在任何php页面上，它就会解决您的问题。
函数将删除字符串开头和结尾的空白。如果要删除字符串中任何位置的换行符，可以执行以下操作：

[...snip...]
            echo $row2['value'];
} ?></g:brand>   <---closing tag up against closing PHP tag
<g:mpn><?php echo $row['sku']; ?></g:mpn>
</item>
<?php    <---eliminated blank lines before php tag
}
mysql_close($con);
?>
[...snip...]


str_replace（数组（“\n”，“\r\n”），“，$row['short_description']；）；

如果你对数据如何存储在数据库中有控制权，我会考虑用类似的函数“清洗”输入，这样你就不必把这个页面弄乱了。
 你可以把它变成这样的：

[...snip...]
            echo $row2['value'];
} ?></g:brand>   <---closing tag up against closing PHP tag
<g:mpn><?php echo $row['sku']; ?></g:mpn>
</item>
<?php    <---eliminated blank lines before php tag
}
mysql_close($con);
?>
[...snip...]

[…剪断…]
echo$row2['value']；
} ?>   
[…剪断…]
