Question

In order to pass an array in the code of create_function(), passing it to the parameter works,

$array = array('a', 'b', 'c');

$func = create_function('$arr', '
            foreach($arr as $var) echo "$var<br />";
        ');

$func($array);

But I’d like to embed an array in the code directly like the eval() capability. Like this,

$array = array('a', 'b', 'c');
eval( 'foreach($array as $var) echo "$var<br />";');

However, this doesn’t work.

$array = array('a', 'b', 'c');

$func = create_function('', '
            foreach(' . $array . ' as $var) echo "$var<br />";
        ');

$func();

So how do I do it? Thanks for your info.

Answer 1

In case you insist on create_function instead of lambda functions

$func = create_function('', '
  foreach(' . var_export($array, true) . ' as $var) echo "$var<br />";
');

You need a (valid) string representation of the array for the php parser. var_export provides that.
