基本上我收到的是：

<iframe width='425' height='350' frameborder='0' scrolling='no' marginheight='0' marginwidth='0' src='https://maps.google.com.br/maps?f=q&amp;source=s_q&amp;hl=pt-BR&amp;geocode=&amp;q=R.+Alm%C3%A9ria,+242+-+Penha,+S%C3%A3o+Paulo+-+S%C3%A3o+Paulo&amp;aq=0&amp;oq=Rua++Almeria&amp;sll=-14.239424,-53.186502&amp;sspn=79.602428,135.263672&amp;t=h&amp;ie=UTF8&amp;hq=&amp;hnear=R.+Alm%C3%A9ria,+242+-+Penha,+S%C3%A3o+Paulo,+03654-000&amp;z=14&amp;ll=-23.524401,-46.518859&amp;output=embed'></iframe>

我需要做的是用另一个值替换width="引号或双引号内的任何值。

我不擅长正则表达式，尝试用这个来学习似乎很复杂。

知道吗？

谢谢。

不久前我回答了一个类似的问题->如何使用php替换iframe html标记的宽度和高度？

更好地使用str_replace()，它更容易，尤其是当您对正则表达式不熟悉时。

找到一种方法，现在，425 ans 350可以是任何值，并用单引号或双引号报价：

<?php
