Pass a PHP array to a JavaScript function

Use JSON.

In the following example $php_variable can be any PHP variable.

<script type="text/javascript">
    var obj = <?php echo json_encode($php_variable); ?>;
</script>

In your code, you could use like the following:

drawChart(600/50, <?php echo json_encode($day); ?>, ...)

In cases where you need to parse out an object from JSON-string (like in an AJAX request), the safe way is to use JSON.parse(..) like the below:

var s = "<JSON-String>";
var obj = JSON.parse(s);

$('#urlresults .concept-name').each(function(){$(this).html()});

$('#urlresults .concept-name').each(function (){if ($(this).html() === 'tarot readings') {$(this).html("test")}});

$('#urlresults .concept-name').each(function (){if ($(this).html() === 'test') {$(this).next(".block").html("block")}});

$('#urlresults .concept-name').each(function (){if ($(this).html() === 'bikini photos') {$next = $(this).next(".block"); $next.html($next.attr('data-tld'))}});

$('#urlresults .concept-name').each(function (){if ($(this).html() === 'bikini photos') {$next = $(this).next(".block"); $next.html(generateUnblockConceptLink($next.attr('data-tld'), $next.attr('data-basis'), $next.attr('data-admin-id'), $next.attr('data-url')))}});
