Switch to preg_replaceDocsand update the expression to use preg syntax (PCRE) instead of ereg syntax (POSIX) where there are differencesDocs(just as it says to do in the manual for ereg_replaceDocs).
切换到preg_replaceDocs并更新表达式以使用 preg 语法 (PCRE) 而不是 ereg 语法 (POSIX) ，其中Docs存在差异（正如它在ereg_replaceDocs手册中所说的那样）。
Your above code should be this way:
你上面的代码应该是这样的：
$jquery_click_hook = preg_replace("[^A-Za-z0-9]", "", strtolower($value['name']));
回答by KinjalMistry
ereg_replace function was DEPRECATED in PHP 5.3.0, and REMOVED in PHP 7.0.0. So you must have to use preg_replace()function instead of ereg_replace()
ereg_replace 函数在 PHP 5.3.0 中被弃用，在 PHP 7.0.0 中被移除。所以你必须使用preg_replace()函数而不是 ereg_replace()
