PHP preg_replace（）使用

Question

I'm trying to change some parts of a string. I used preg_replace() function for this stuation but I couldn't succeed.

Here is an example.

$str = "Suspendisse rutrum rhoncus leo vitae vehicula. <span class="sdsad"> Nunc nec dapibus nisi.</span> Donec facilisis mauris sapien, eget blandit enim  dignissim auctor. <span style="text-decoration: underline;" class="sadsad">Nullam a porta orci.</span>";

I need to get parts begin with "<span" and after all till ">" charecter and turn it <p> or something else.

$str = preg_replace('/<span.*>/', '<p>', $str);

I'm trying to solve this like that but it returns the same value.

What do I need to do this ?

Thank you..

Answer 1

This Regex will do the trick for you.

$str = 'Suspendisse rutrum rhoncus leo </span> vitae vehicula. <span class="sdsad"> Nunc nec dapibus nisi.</span> Donec facilisis mauris sapien, eget blandit enim  dignissim auctor. <span style="text-decoration: underline;" class="sadsad">Nullam a porta orci.</span>';
$str_replaced = preg_replace('/<(\/{0,1})span[^>]*>/','<$1p>',$str);
echo $str_replaced;

It will optionally put the trailing slash into the tags so you will only need one call.

Answer 2

You forgot the capturing group here ()

$str = preg_replace('/<span(.*)>/', '<p>', $str);
