    Question How To Check Whether An Html Element Or Plain Text Exists On A Page Or Not


    Imagine you want to only provide your download link to those who tweet about you. Now, how would you code it ?
    Let's make it simple for you to understand.
    Let's say you want to write a php script that checks if a certain html element (eg. name=username) or plain text exists or not.
    If it exists then to give you an alert "TRUE"; Else alert: FALSE.

    In this example, you want the script to check this page:

    And you want it to check if the following text (exact match) exists or not:
    "I'd like to put forward an Idea"

    How would you code it ? Can we see 2-3 examples ?
    I'd be grateful if you can show another example for a fuzzy match. Eg:
    * like to put forward *

    This is an interesting topic. Base the boolean around what exists or not on a page.
    Curious to see what the code would look like and php is capable of doing it in how many lines of code.

    I'd start by seeing if the Twitter API would give me a dependable way to do it. https://dev.twitter.com/overview/api
