title: How can i read a file in php only to a certain character
body: <p>the fseak function sets a cursor to the file but only an offset, a number.  Is there a function or a way i can set the cursor to a text file after reading a character or a string?  Example, lets say i have this text file:</p>
  
  <p>Hi, welcome to your page!</p>
  
  <p>Is there a way i can insert my name for instance, right after the word "Hi" in the text file?</p>
