Question

I have the following code:

<?php
    if ($zweck == "buchhaltung") {
        echo <<<EOF
        <script type="text/javascript">
            jQuery(document).ready(function() {
            jQuery("#$grid_name").jqGrid({
                url: 'modules/mod_jqgrid/ex_get3.php?tb=$tb'
                .....
        </script>
EOF;
    };
?>

… which does not seem to render properly.
Can’t we use PHP variables in heredoc in JavaScript code like I use it on the second last line?

On the last line I use ” ‘ ” around the PHP variable $tb. Is this syntax correct?

The following code is inside the heredoc as JavaScript code:

dataInit:function(el){
    $(el).datepicker({dateFormat:'dd.mm.yy'});
},
defaultValue: function(){

// Maybe PHP "thinks" that $(el) is a PHP variable?

var currentTime = new Date();

Answer 1

Variable expansion is performed in heredoc strings, so that’s not the problem. The code you give should work fine; if it does not, maybe something else is amiss? What exactly do you mean “does not render properly”?
