HomeBackend DevelopmentPHP Tutorial关于php 用html2pdf 生成 pdf 文件问题

各位高手:请教您一个问题,我用php html2pdf 生成动态pdf,发现一个问题,例如在html文件中输入超过一行长度的字符(如:200个字符),那么生成的pdf,只能显示一行,不会自动换行,除非我手工在html文件中通过\n 或 
做了换行处理才显示正常。通过实例top bottom righ  left设置边距没有用。谢谢!有遇到这样问题的人不??

代码如下:
      $html2pdf = new HTML2PDF('P', 'A4', 'fr', true, 'UTF-8', array(30, 20, 25, 25));
        $html2pdf->pdf->SetDisplayMode('fullpage');

注:此代码中array(30, 20, 25, 25)  设置的边距仅仅对html已换行起作用。


回复讨论(解决方案)

附图如下:

问题aaaaaaa超过pdf页面了,而且很多aaa没有显示

html2pdf 是通过分析 css 来实现在 pdf 中构图的
就是说,如果你的 css 是错的或是他不认识的,则必然会影响到pdf页的效果

如果你的 aaaa.... 在用主流浏览器观看时,会有折行的话,那么 html2pdf 也会折行

这是HTML2PDF的问题,你改变不了它,只能适应它。
如果是你自己能控制的网站页面,还可以适应。
但如果是你想处理其它网站的页面,那你只能另寻工具。

非常感谢两位,我想问的是我通过表格或div来控制宽度(如width=500px;或width=50%,

aaaaaaaaaaaa(很长))如果是网页的形式展示是能自动换行的,但用html2pdf生成pdf就不行,是html2pdf还有些功能我没研究透彻还是压根没有这个功能???谢谢

有谁用过这个功能的,这个问题很常见呀。我现在是通过php判断字符长度来换行,但这有个问题,汉字和字母、数字占的大小不一样,例如如果全是汉字,我字体大小为14px,那么32个汉字刚好一行,我就写入
,但关键是有很多情况汉字夹杂字母数字,如果还是按照32个字符来换行,整个就长短不一。

对于 

aaaaaaaaaaaaaaaaaaaaaaaaa(很长)

没有指定排列方式时:
如果没有“(很长)”则不会折行,只有“(很长)”处会折行

已超过页面长度,很长很长,正常情况下网页形式展示能换行,但通过html2pdf生成的pdf文件就不换行,只能显示这个页面的长度,就一行
