Question

我正在使用以下代码删除Wordpress添加到媒体文件名的大小。

function replace_content($content) {
    $content = preg_replace('/-([^-]*(\d+)x(\d+)\. ((?:png|jpeg|jpg|gif|bmp)))"/', '.${4}"', $content);
    return $content;
}
add_filter('the_content','replace_content');

如何更改正则表达式以仅将其应用于href属性值？

Answer 1

带有preg_replace（）函数的正则表达式

s = '\xd1\x84\xd0\xbe\xd1\x80\xd1\x83\xd0\xbc'.encode().decode('unicode_escape') [having the bytes part between '' been gotten from a file using the open(file,"r") function, in my case]
s.encode('latin-1').decode('utf-8') [or ISO-8859-1, as it seems it's the same thing]

清除此可怕的img标签

$replaced_content = preg_replace( '#<img[^>]*?src[\s]?=[\s]?[\'"]?([^\'">]*?(https|http|\/\/)[^\'">]*?(png|jpeg|jpg|gif|bmp))[^\'" >]*?)[\'" ][^>]*?>#',
                                  '<img src="$1">', $content );

这个干净漂亮的代码
