I'd be inclined to do it with the tokenizer functions with something
like this (untested):
<?php
$source = file_get_contents($argv[1]);
$token = token_get_all($source);
foreach ($token as $t) {
if (is_string($t)) {
print $t;
continue;
}
switch ($t[0]) {
case T_OPEN_TAG_WITH_ECHO:
print '<?php echo ';
break;
case T_OPEN_TAG:
print '<?php ';
break;
case T_CLOSE_TAG:
print ' ?>';
break;
default:
print $t[1];
}
}
?>
