'reg' => "\bprimaryColour:\s?['\"][a-z0-9 ,._+;()'@!?&#:\/-]+['\"]",
'string' => "primaryColour: \"".$settings['new_primary_colour_ccs']."\"",
'value' => $settings['new_primary_colour_ccs']
]

(n["createCommentVNode"])("", !0)])]), Object(n["createELementVNode"])("div"

据我所知，您需要应用模式分隔符和不区分大小写。请参阅模式外部的分隔字符和尾部，以表示正则表达式引擎应使用不区分大小写（因为十六进制颜色代码全大写）。~i
此外，您应该避免不必要地一遍又一遍地获取和保存相同的内容。相反，获取一次文件内容，执行所有处理，然后保存一次。
代码：（演示)
$settings['new_primary_colour_ccs'] = '#777777'; // test color
foreach ($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, $content);
}
如果在实际应用程序中，父循环内没有更改，请将声明移到该循环上方。继续使用相同的数据重新声明它是没有意义的。$styleSettings
