index.php使用GET POST DELETE PUT方法

Question

我在使用.htaccess操作index.php时遇到了一些问题，当我提交表单然后选择删除/放置按钮时，它不会进入条件if（$ _ SERVER [“REQUEST_METHOD”] == DELETE /放） 它进入请求方法为GET的条件，对于方法POST我必须将form.html文件移动到另一个目录，以便当我在浏览器上启动它时它不会更改其URL 我尝试在互联网上搜索，但我找不到可以提供帮助的东西，如果有人能提供帮助，我真的很感激！下面是index.php的源代码：

<?php
function ajouterPortraits($f){

            $f = fopen($f,"a+");

            if($_POST != null){
                fwrite($f,"\n");
                fwrite($f, count(file("galerie.txt"))+1);
                fwrite($f," | ");

                if(isset($_POST["prenom"])){

                    fwrite($f, $_POST["prenom"]." | ");
                    unset($_POST["prenom"]);
                }
                if(isset($_POST["nom"])){
                    fwrite($f, $_POST["nom"]." | ");
                    unset($_POST["nom"]);
                }

}

.htaccess代码：

    <IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME] !-f
RewriteCond %{REQUEST_FILENAME] !-d
RewriteRule TP3M/(.*)$ TP3M/index.php?request=$1 [QSA,NC,L]
</IfModule>

和form.html代码：

<form action="TP3M/index.php" method="POST" enctype="multipart/form-data" >
        <fieldset>
            <legend>Ajout de personne</legend>
            <label for="prenom">Prenom :</label>
            <input type="text" name="prenom" id="prenom" ><br>
            <label for="nom">nom :</label>
            <input type="text" name="nom" id="nom"><br>
            <input type="radio" name="sexe" value="Homme"/>Homme<br>
            <input type="radio" name="sexe" value="Femme"/>Femme<br>
            <input type="file" name="photo" accept="image/jpg"><br>

            <input type="submit" value="Valider">
        </fieldset>
    </form>
