How can I convert ereg expressions to preg in PHP?

我有能力制作我在网上找到的SEO链接的功能，但是使用最新的PHP它因为ereg_replace而无效。有人可以帮我把它改成preg_replace。

function generate_seo_link($FieldName, &$CurrVal, &$CurrPrm){
        //make it lowercase, remove punctuation, remove multiple/leading/ending spaces
        $rep = trim(ereg_replace(' +',' ',preg_replace('/[^a-zA-Z0-9\s]/','',strtolower($CurrVal))));
        //convert the spaces to whatever the user wants
        //usually a dash or underscore..
        //...then return the value.
        $CurrVal = str_replace(' ','-',$rep);
}

Answer 1

您只需将ereg_replace更改为preg_replace，就像这样

function generate_seo_link($FieldName, &$CurrVal, &$CurrPrm){
    //make it lowercase, remove punctuation, remove multiple/leading/ending spaces
    $rep = trim(preg_replace('/ +/',' ',preg_replace('/[^a-zA-Z0-9\s]/','',strtolower($CurrVal))));
    //convert the spaces to whatever the user wants
    //usually a dash or underscore..
    //...then return the value.
    $CurrVal = str_replace(' ','-',$rep);
}

对于preg_replace，您必须使用分隔符封装正则表达式（注意正则表达式中的周围/）。
