Replacing text within a string

Question

I would like to use PHP to replace hash-tagged words in strings of text.

My String:

"Working on some cool things for shareit.me #ui #webdesign #ux"

I would like to encapsulate each hash-tagged keyword with span tags to give them a different color. How can I do this?

Thanks!

Try with 'preg_replace' like

preg_replace('/(^|\s)#(\w+)/','<span style="color:green;">\2</span>',$my_string);

if you want each tag different color

str_replace(array('#ui', '#webdesign', '#ux'), array('<span style="color:red">#ui</span>', '<span style="color:green">#webdesign</span>', '<span style="color:blue">#ux</span>'), "Working on some cool things for shareit.me #ui #webdesign #ux");

if you want replace all #tag

preg_replace('/#(\w\d+?)/', '<span style="color: red">#$1</span>', "Working on some cool things for shareit.me #ui #webdesign #ux");
