Array formatting doesn't look correct - php

Question

In the code below, I'm pulling apart a CSS file and trying to return in an array. It's working, but my formatting looks weird. What did I do wrong?
Sample of what I'm looking for:
Array
(
[body] => Array
(
[width] => 100%
[background-color] => #e6e6e6
)
)
My code:
$file = file_get_contents($_SERVER['DOCUMENT_ROOT'] . '../parse-css-upload/' . $this->newFileName);
$element = explode('}', $file);
$css_array = array(); // master array to hold all values
$element = explode('}', $file);
foreach ($element as $element) {
// get the name of the CSS element
$a_name = explode('{', $element);
$name = $a_name[0];
// get all the key:value pair styles
$a_styles = explode(';', $element);
// remove element name from first property element
$a_styles[0] = str_replace($name . '{', '', $a_styles[0]);
// loop through each style and split apart the key from the value
$count = count($a_styles);
for ($a=0;$a<=$count;$a++) {
if ($a_styles[$a] != '') {
$a_key_value = explode(':', $a_styles[$a]);
// build the master css array
$css_array[$name][$a_key_value[0]] = $a_key_value[1];
}
}
}
Actual outpt:
Array
(
[body, html ] => Array
(
[
width] => 100%
[
background-color] => #e6e6e6
[
] =>
)
[
body ] => Array
(
[
font-family] => "Open Sans", sans-serif
[
color] => #686868
[
font-size] => 16px
[
font-weight] => 300
[
line-height] => 1.7
[
] =>
)

Answer 1

Try :
$css_array[$name][trim($a_key_value[0])] = trim($a_key_value[1]);
You have new line characters around.

Answer 2

Try this hope this will help
for ($a=0;$a<=$count;$a++) {
if (trim($a_styles[$a]) != '') {
$a_key_value = explode(':', $a_styles[$a]);
// build the master css array
$css_array[trim($name)][trim($a_key_value[0])] = trim($a_key_value[1]);
}
}
Use trim in your code
