The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
Tested and works :)
ReplyDelete$array = array( "a" => "1", "b" => "2", "c" => "3" );
function replace_key($array, $old_key, $new_key) {
$keys = array_keys($array);
if (false === $index = array_search($old_key, $keys)) {
throw new Exception(sprintf('Key "%s" does not exit', $old_key));
}
$keys[$index] = $new_key;
return array_combine($keys, array_values($array));
}
$new_array = replace_key($array, "b", "e");
One way would be to simply use a foreach iterating over the array and copying it to a new array, changing the key conditionally while iterating, e.g. if $key === 'foo' then dont use foo but bar:
ReplyDeletefunction array_key_rename($array, $oldKey, $newKey)
{
foreach ($array as $key => $value) {
$newArray[$key === $oldKey ? $newKey : $key] = $value;
}
return $newArray;
}
Another way would be to serialize the array, str_replace the serialized key and then unserialize back into an array again. That isnt particular elegant though and likely error prone, especially when you dont only have scalars or multidimensional arrays.
A third way - my favorite - would be you writing array_key_rename in C and proposing it for the PHP core ;)
Something like this may also work:
ReplyDelete$langs = array("EN" => "English",
"ZH" => "Chinese",
"DA" => "Danish",
"NL" => "Dutch",
"FI" => "Finnish",
"FR" => "French",
"DE" => "German");
$json = str_replace('"EN":', '"en":', json_encode($langs));
print_r(json_decode($json, true));
OUTPUT:
Array
(
[en] => English
[ZH] => Chinese
[DA] => Danish
[NL] => Dutch
[FI] => Finnish
[FR] => French
[DE] => German
)
Do a double flip! At least that is all I can think of:
ReplyDelete$array=("foo"=>"bar","asdf"=>"fdsa");
$array=array_flip($array);
$array["bar"]=>'newkey';
$array=array_flip($array);
You could use array_combine. It merges an array for keys and another for values...
ReplyDeleteFor instance:
$original_array =('foo'=>'bar','asdf'=>'fdsa');
$new_keys = array('abc', 'def');
$new_array = array_combine($new_keys, $original_array);
