Question

我需要制作表格。首先，我需要一个选择让您选择group1，group 2或两者。其次，有一个复选框，询问您是否要显示未通过课程的组中的人员。

<?php
$NotesGroupe1 = array(
 "HARG200181" => array("Guillaume", "Harvey", "M", 36, 90, 70, 76),
 "CHAM010283" => array("Marc-André", "Charpentier", "M", 34, 80, 73, 96),
 "TREV290991" => array("Valérie", "Tremblay", "F", 26, 70, 71, 69),
 "PELL180584" => array("Laurence", "Pelletier", "F", 30, 65, 89, 76),
 "MALF110194" => array("Francis", "Maltais", "M", 20, 61, 50, 59),
 "GAUM220654" => array("Martine", "Gauthier", "F", 60, 65, 40, 76),
);
$NotesGroupe2 = array(
 "GIRM230383" => array("Marc-Olivier", "Girard", "M", 31, 75, 85, 56),
 "TREM300878" => array("Michel", "Tremblay", "M", 36, 50, 50, 55),
 "POID250468" => array("Diane", "Poitras", "F", 46, 61, 75, 59),
 "LEML180586" => array("Laurence", "Lemieux", "F", 31, 80, 89, 100),
 "VANL130395" => array("Jeff", "Van Cleef", "M", 19, 61, 68, 33)
);

之后，您需要一个无线电按钮，告诉您是否需要等级男性或女性或两者兼而有之。

    <form method="GET">
            <div class="menu">
                <?php include 'menu.php';?>
            </div>
            Choisir une groupe : 
            <select name="groupe">
                            <option value='0'>Groupe 1</option>
                            <option value='1'>Groupe 2</option>
                            <option value='3'>Groupe 1 & 2</option>
            </select>
            <br>
            Affichez seulement les notes des élèves en situation d'échec.
            <input type="checkbox" name="echec" value="selectionner"/><br>
            Affichez hommes & femmes : <input type="radio" name="sexe" value="M|F" checked="checked"/>
            Affichez seulement les hommes : <input type="radio" name="sexe" value="M"/>
            Affichez seulement les femmes : <input type="radio" name="sexe" value="F"/>
            <br>
            <input type="submit" value="Soumettre"/>
            <?php
            require_once("tableaux.php");
              if(isset($_GET["groupe"])&& isset($_GET["sexe"])){
                    $groupeNumber = $_GET["groupe"];
                    $sexe = $_GET["sexe"];
                    $pregSexe = "/" . $sexe . "/im"; 
                    $groupe = "";
                    if($groupeNumber == 0){
                            $groupe = $NotesGroupe1;
                    }else if ($groupeNumber == 1){
                            $groupe = $NotesGroupe2;    
                    }
                    else{
                            $groupe=$NotesGroupe1+$NotesGroupe2;
                    }
                    if ( preg_match($pregSexe, $sexe)){

                    }else if ( preg_match($pregSexe, $sexe)  ){

                    }
                    else if( preg_match($pregSexe, $sexe){

                    }

                    if(isset($_GET["echec"]){
                        $echec = $_GET["echec"];
                        if ($echec == true){

                        }
                        else{   
                        }
                    }
              }
            ?>

我没有完成代码，我似乎无法将与性别相关的组中的失败成绩联系起来。我无法修改数组，所以有什么可以帮助我。感谢

您可以将array_filter()与自定义函数一起使用，以根据正则表达式减少数组。

$NotesGroupe1 = array(
 "HARG200181" => array("Guillaume", "Harvey", "M", 36, 90, 70, 76),
 "CHAM010283" => array("Marc-André", "Charpentier", "M", 34, 80, 73, 96),
 "TREV290991" => array("Valérie", "Tremblay", "F", 26, 70, 71, 69),
 "PELL180584" => array("Laurence", "Pelletier", "F", 30, 65, 89, 76),
 "MALF110194" => array("Francis", "Maltais", "M", 20, 61, 50, 59),
 "GAUM220654" => array("Martine", "Gauthier", "F", 60, 65, 40, 76),
);
$groupe = $NotesGroupe1 ;
$sexe = 'F'; // arbitrary value but come from your $_POST.
$pregSexe = '/'.$sexe.'/im' ; // eg. '/F/im', '/M/im', or  '/M|F/im' 
$groupe = array_filter($groupe, function($element) use ($pregSexe) {
    return preg_match($pregSexe, $element[2]) ;
});
print_r($groupe);

该函数是一个匿名函数，$pregSexe使用use()在其范围内访问true。此函数返回一个布尔值：false保持，"F"拒绝。

在上面的代码中，只有第三个键Array ( [TREV290991] => Array ([0] => Valérie [1] => Tremblay [2] => F [3] => 26 [4] => 70 [5] => 71 [6] => 69 ) [PELL180584] => Array ([0] => Laurence [1] => Pelletier [2] => F [3] => 30 [4] => 65 [5] => 89 [6] => 76 ) [GAUM220654] => Array ([0] => Martine [1] => Gauthier [2] => F [3] => 60 [4] => 65 [5] => 40 [6] => 76 ) )的数组元素保留在最终数组中。

library(tidyverse)

mtcars <- as_tibble(mtcars)

mtcars$cyl <- as.factor(mtcars$cyl)

model1 <- glm(mpg ~ cyl + hp, data = mtcars)
summary(model1)

Php表关联
