limit text length in php and provide Read more link

Question

I have text stored in the php variable  text  This text can be 100 or 1000 or 10000 words  As currently implemented  my page extends based on the text  but if the text is too long the page looks ugly   I want to get the length of the text and limit the number of characters to maybe 500  and if the text exceeds this limit I want to provide a link saying   Read more   If the  Read More  link is clicked  it will show a pop with all the text in  text

There is an appropriate PHP function  substr replace  text   replacement   start    For your case  because you already know all the possibilities of the text length  100  1000 or 10000 words   you can simply use that PHP function like this   echo substr replace  your text         20     PHP will automatically return a 20 character only text with       Se the documentation by clicking here
