Question

I have an array of values that I would like to run through htmlspecialchars but with an argument such as this:

$param = htmlspecialchars($param, ENT_QUOTES);

The problem is, I have an array of values that I want to run htmlspecialchars on:

$array = array_map('htmlspecialchars', $array);

and I would like to know if there is a way to pass ENT_QUOTES into the array_map callback?

I can always use my own function that uses htmlspecialchars, but it would be nice if there was a way to do this already.

After the answer below, here is my end result:

$array = array_map('htmlspecialchars', $array, array_fill(0, count($array), ENT_QUOTES));

Which simply fills an array with as many values as $array has and it’s filled with ENT_QUOTE.

Answer 1

This should work if you pass a second array as parameter to array_map that will contain as many ENT_QUOTES elements as your number of elements in $array:

$quote_style = ENT_QUOTES;
$array = array('"',"'","''''''''''''\"");
$ent_quotes_array = array($quote_style, $quote_style, $quote_style);
$array = array_map('htmlspecialchars', $array, $ent_quotes_array);
print_r($array);

Or, a little bit more elegant:

$array = array('"',"'","''''''''''''\"");
$ent_quotes_array = array_fill(0, sizeof($array), ENT_QUOTES);
$array = array_map('htmlspecialchars', $array, $ent_quotes_array);
