Passing values from PHP

[anush]

In a javascript file, I have to pass PHP values to the innerHTML. Can
anybody tell how I could do it.

innerHTML = "<?php echo $escapedToBeSafeForJSValue; ?>";

innerHTML = "<?php echo $escapedToBeSafeForJSValue; ?>";

That may be a little ambiguous though - as innerHTML is a property of
DOM element nodes. Maybe:

html_value1 = "<?php echo $escapedToBeSafeForJSValue; ?>";
.. . .
your_element.innerHTML=html_value1;

And of course, make sure you've had PHP escape the value properly (as
implied by David).

I am sure that was meant.

Maybe:

html_value1 = "<?php echo $escapedToBeSafeForJSValue; ?>";

Always declare your identifiers:

var html_value1 = ...

. . .
your_element.innerHTML=html_value1;

There is little reason for another variable here:

Full ACK. http://php.net/addslashes

Good point.

your_element.innerHTML = "<?php echo $escapedToBeSafeForJSValue; ?>";

Unless you wanted to pre-populate a variable for insertion at a later
point (an assumption)

A tip: I like to use json_encode for this:

var value = (<?php echo json_encode($variable); ?>);

If it's a string, it will automatically be escaped properly and
surrounded with quotes. But you can also pass numeric data, arrays, and
anonymous objects in this fashion, which is pretty convenient.

json_encode/decode is included with PHP >= 5.2.
