JavaScript regex for PHP block <?php echo $imagePath; ?>

Question

I want to write a regex for the below PHP block and want to replace it with the actual image path.

<?php echo $imagePath; ?>

I have tried

str.replace(/<\?[=|php]?[\s\S]*?\?>/g, 'images/dir1/');

but it is replacing all other PHP blocks of the page also. I want a regex which replaces a particular PHP block.

you should not operate php code from js code. This <?php echo $imagePath; ?> should be rendered, then you may do replacement — RomanPerekhrest

I know we should not. But I am using ckEditor to edit php files and there i want actual path to show images. ckEditor can't render php tags. — Abhi Andhariya

Try using the following regex ...

<\?php\secho\s\$imagePath;\s\?>

JavaScript

var phpblock = '<?php echo $imagePath; ?>';
var result = phpblock.replace(/<\?php\secho\s\$imagePath;\s\?>/g, 'images/dir1/');
console.log(result);

Hey Thanks. It worked. Earlier i tried <\?php\secho \$imagePath;\s\?>. and missed \s between echo and imagePath. Silly.. :P
