I'm reading a file in server with php and storing the file content in a variable. now i want to access the variable with javascript, Since I need to split the contents with tab delimited and add the content as options to a Select tag.

               <?php
                       //read the 'file' content to lines variable
                       $lines = file('file');
                ?>

Javascript to access the PHP variable($lines):

<script type="text/javascript" >
    function readData(){
        var s = '<? echo $lines ?>';
        alert(s);
        }
</script>

Where alert pops up only with Array text

What Should I do so that the data stored in $lines array will be accessed in javascript array variable

Answer 1

file_get_contents('file') instead of file('file') is your best bet.
