从数组键PHP删除方括号

Question

I'm needing some help with an array. I know this is more than likely a simple solution, but I'm new so I apologize! I've been stuck on this for a while.

This is the current array that I've got:

Array ( [0] => 3 [1] => 2 [2] => 5 [3] => 2 )

I need the array to look like this:

Array ( 0 => 3, 1 => 2, 2 => 5, 3 => 2 )

I'm trying to pass this information to HighCharts and it won't accept the array in the format I currently have.

Thank you!!!

Answer 1

Something like this should work

// your array according to your question
$someArray = array();
$someArray[0] = 3;
$someArray[1] = 2;
$someArray[2] = 5;
$someArray[3] = 2;

// begin string output
$toHighCharts = 'Array(';

// loop through current array items
foreach($someArray as $k=>$v)
{
    // append string with desired format
    $toHghCharts.= $k.'=>'.$v.',';
}

// remove trailing comma
$toHighCharts = substr($toHighCharts, 0, -1);

// end string output
$toHghCharts.= ')';

// output string output
echo $toHighCharts;

have you tried to convert the Array to a JavaScript Array with jsonencode?

For example:

var jsarray= <?php echo json_encode($phparray); ?>;
