Some time you may need to encode a javascript function into a JSON object. json_encode does not
support it yet.
array example:
<?php
$series = array("name"=>"N51",
"data"=>array(1024,
array("y"=>2048,
"events"=>array("mouseOver"=>'function(){$reporting.html(\'description
of value\');}')
),
4096)
);
json_encode($series);
?>
output:
{"name":"N51","data":[1024,{"y":2048,"events":{"mouseOver":"function(){$reporting.html('description
of value');}"}},4096]}
<?php json_encode_jsfunc($series); ?>
output:
{"name":"N51","data":[1024,{"y":2048,"events":{"mouseOver":function(){$reporting.html('description
of value');}}},4096]}
The difference is quotes around function, there should not be quotes.
<?php
function json_encode_jsfunc($input=array(), $funcs=array(), $level=0)
{
foreach($input as $key=>$value)
{
if (is_array($value))
{
$ret = json_encode_jsfunc($value, $funcs, 1);
$input[$key]=$ret[0];
$funcs=$ret[1];
}
else
{
if (substr($value,0,10)=='function()')
{
$func_key="#".uniqid()."#";
$funcs[$func_key]=$value;
$input[$key]=$func_key;
}
}
}
if ($level==1)
{
return array($input, $funcs);
}
else
{
$input_json = json_encode($input);
foreach($funcs as $key=>$value)
{
$input_json = str_replace('"'.$key.'"', $value,
$input_json);
}
return $input_json;
}
}
?>
