Parsing

I am wondering if someone could help me parse the text that appears above "On 15-02-19 02:31 PM, The Verse of the Day Inquiries wrote:" from the variable" $correspondence " $correspondence = <<<EOF Looking to see if this message is appended to the original ticket # 3784. Sent to inquiries@theverseoftheday.info On 15-02-19 02:31 PM, The Verse of the Day Inquiries wrote:

*=== To reply please type your response ABOVE THIS LINE ===* EOF;

What I have worked out so far is: if ( strpos( $correspondence , '=== To reply please type your response ABOVE THIS LINE ===' ) ) {

        $correspondence = substr(
            $correspondence,
            0,
            strpos(
                $correspondence,
                '=== To reply please type your response ABOVE THIS LINE

==='

            )
        );

} The date time and business e-mail account name will be dynamic. The type of pattern to match would be - starting with "On" - ending with "wrote:" Thank you for any help / guidance.
