On my text examples it seems to look good but I think it's not much
different than using a \s
<?
if ($foo)
?>
<?= $foo ?> <?=$foo;?>
<? if($foo) ?>
<?php $foo='bar'; ?>
<?= $foo ?>
<?=$foo?>
<?echo 'i told you so';?>
<?phpecho 'this one fails';?>
If I substitute '<?php' then I end up with this:
<?php
if ($foo)
?>
<?= $foo ?> <?=$foo;?>
<?php if($foo) ?>
<?php $foo='bar'; ?>
<?= $foo ?>
<?=$foo?>
<?phpecho 'i told you so';?> <-- this one breaks now though
<?phpecho 'this one fails';?> <-- don't care as it was broken to begin
with
Is there a way to tweak the substitution with that same lookahead idea
so if
it was <? Followed by a character NOT a = then it adds a space?

Use a lookahead:
<\?(?!(=|php))

The ONLY one that gives a parser error is the LAST one where yes, a
space is required after a <?php
That is NOT the case for <? or <?=

What I posted (and all the others) would work, replacing all
instances of
"<? " (notice the space) with "<?php " should work, it will leave
all
existing <?= and <?php alone (since having a space after ? and
before
=/php would produce a parser error.
Not sure why you are saying that spaces are irrelevant thou.

<?=$foo?> is perfectly valid so is <?=$foo;?> or any combination
WITH
SPACES OR NOT.
If this were trivial, I wouldn't have asked the list. I've been
coding PHP
since 1996. ;-)
So if you have <? you have to make sure it doesn't have a '='
after
the
'?' to convert to '<?php'
Spaces are irrelevant and can NOT be relied upon as a unique
feature.

Thanks guys for the replies so far, however, if it were a simple
search
and
replace I wouldn't have to ask ;-)
The trick is that "<?=" is valid and legal and I want to keep
those. I
only
want to change if they are specifically "<?"
Maybe there is some regex guru out there that knows the magic
incantation.
Related, for extra credit it drives me bonkers to see this:
Hello <?= $username; ?>
Note the end semicolon on the variable. I'd want to strip all
those
off
too,
but that is also not a trivial task if you think about it as it
can
only
be
removed if proceeded with <?=
