Heredoc Returning Unexpected End

PHP Heredoc unexpected end of file error

That specific error can result from white-space / tab indentation on the same line after the closing HEREDOC: Most people catch the opening white-space issue, this one is obviously harder to see.

When in doubt with HEREDOC blocks try and eliminate all possible white-space and indentations.

Possible Dupe: Why do these Heredoc and Nowdoc cause errors?

here-document gives 'unexpected end of file' error

The EOF token must be at the beginning of the line, you can't indent it along with the block of code it goes with.

If you write <<-EOF you may indent it, but it must be indented with Tab characters, not spaces. So it still might not end up even with the block of code.

Also make sure you have no whitespace after the EOF token on the line.

PHP Unexpected end of file

You appear to have some spaces after your heredoc closing identifier.

From the manual:

It is very important to note that the line with the closing identifier
must contain no other characters, except a semicolon (;). That means
especially that the identifier may not be indented, and there may not
be any spaces or tabs before or after the semicolon.

Parse error: syntax error, unexpected $end

The HereDOC ( $og_video = <<<HTML ) is wrong, it has to be a the direct start of a line.
Check: http://php.net/manual/en/language.types.string.php for details on this.
Also remove any whitespace after HTML, that causes errors too.

Otherwise, there's really nothing wrong with it, should work quite nicely.

in bash, heredoc inside function returns syntax error

Your function declaration is wrong:

get_instance{

should be one of

function get_instance {
get_instance() {

Put the close bracket on a different line:

dbname=$(sqlplus -s / as sysdba<<EOF
...
EOF
)

The terminating word of the heredoc should be the only characters on the line (except tabs when using <<-). Demo:

$ x=$(cat <<END
> one
> two
> END)
bash: warning: here-document at line 5 delimited by end-of-file (wanted `END')
$ echo "$x"
one
two

So it worked, accidentally. Better practice is:

$ y=$(cat <<END
> 1
> 2
> END
> )
$ echo "$y"
1
2

Heredoc not working

The parser is complaining because you have whitespace after the angled brackets declaring a heredoc. You need to make sure you're actually following the heredoc syntax, which you can find on the PHP Manual site (specifically: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc).

<?php
$information = <<<ENDHEREDOC
this is my text
ENDHEREDOC;
echo $information;

here document - unexpected end of file

The <<- form of here documents are very sensitive to leading whitespace. They only allow for tabs. If you accidentally used leading space or your editor expands tabs automatically, the here document would never find its closing token, and that would account for the error you see.

If you want to maintain your indentation, but want an alternative to the <<- notation, consider just using echo or printf, like so:

report() {
    printf '<H2>%s</H2>\n<PRE>%s</PRE>\n' "$1" "$2"
}

report_home_space() {
    report 'Home Space Utilization' "$(du -sh ~/*)"
}
