I need to change my css style using preg_replace

Answer 1

From what I see, you need to apply pattern delimiters and case-insensitivity. See the ~ delimiting characters on the outside of the pattern and the trailing i to signify that case-insensitivity should be used by the regex engine (because the hex color code is in all-caps).
Also, you should avoid needlessly fetching and saving the same content over and over. Instead, fetch the file content once, do all the processing, then save it once.
Code: (Demo)
$settings['new_primary_colour_ccs'] = '#777777'; // test color
foreach ($appPats as $path) {
$styleSettings = [
'primary_colour' => [
'reg' => "~\bprimaryColour:\s?['\"][a-z0-9 ,._+;()'#!?&#:\/-]+['\"]~i",
'string' => 'primaryColour:"' . $settings['new_primary_colour_ccs'] . '"',
'value' => $settings['new_primary_colour_ccs']
]
];
$content = file_get_contents($path);
foreach ($styleSettings as $style) {
$content = preg_replace($style['reg'], $style['string'], $content);
}
file_put_contents($path, $content);
}
If in your actual application, $styleSettings doesn't change inside the parent loop, move the declaration above that loop. It doesn't make sense to keep re-declaring it with the same data.
