This is a function to convert a PHP Array to a Javascript Object variable. The object variable can be accessed like any other object variable. You can traverse the object using the for...in loop.
The first argument to the function is the php array to be converted. The second argument is the name for the javascript object. The third parameter should not be set directly.
| <?php
function arrayToJSObject($array, $varname, $sub = false ) {
$jsarray = $sub ? $varname . "{" : $varname . " = {\n";
$varname = "\t$varname";
reset ($array);
// Loop through each element of the array
while (list($key, $value) = each($array)) {
$jskey = "'" . $key . "' : ";
if (is_array($value)) {
// Multi Dimensional Array
$temp[] = arrayToJSObject($value, $jskey, true);
} else {
if (is_numeric($value)) {
$jskey .= "$value";
} elseif (is_bool($value)) {
$jskey .= ($value ? 'true' : 'false') . "";
} elseif ($value === NULL) {
$jskey .= "null";
} else {
static $pattern = array("\\", "'", "\r", "\n");
static $replace = array('\\', '\\\'', '\r', '\n');
$jskey .= "'" . str_replace($pattern, $replace, $value) . "'";
}
$temp[] = $jskey;
}
}
$jsarray .= implode(', ', $temp);
$jsarray .= "}\n";
return $jsarray;
}
$fruits = array(
array('id' => 1, 'name' => 'Apple', 'color' => 'Red'),
array('id' => 2, 'name' => 'Orange', 'color' => 'Orange'),
array('id' => 3, 'name' => 'Mango', 'color' => 'Yellow')
