Does anyone know how to add text/code before the “<!DOCTYPE html>”?
You can add text before or after the header, but I need to add text/code before the start of the HTML tag. The reason for this, is that PHP prevents redirection/processing if HTML text has already been written to the output buffer.
Any suggestions on how this can be undertaken?
Development Idea: Replicate the same Header “add code/text before/after header” capability but at a page level and global level.
