Question

我想生成随机的20.000个名字。我有3个数组：$ firstNameCollection，$ middleNameCollection和$ lastNameCollection，如下所示:(查看代码），我想生成（随机）20.000个名字。我将附加我的代码，其中只生成1个名称..

$firstNameCollection = array("Harry","Ross",
                        "Bruce","Cook",
                        "Carolyn","Morgan",
                        "Albert","Walker",
                        "Randy","Reed",
                        "Larry","Barnes",
                        "Lois","Wilson",
                        "Jesse","Campbell",
                        "Ernest","Rogers",
                        "Theresa","Patterson",
                        "Henry","Simmons",
                        "Michelle","Perry",
                        "Frank","Butler",
                        "Shirley");

$middleNameCollection = array("Brooks",
                    "Rachel","Edwards",
                    "Christopher","Perez",
                    "Thomas","Baker",
                    "Sara","Moore",
                    "Chris","Bailey",
                    "Roger","Johnson",
                    "Marilyn","Thompson",
                    "Anthony","Evans",
                    "Julie","Hall",
                    "Paula","Phillips",
                    "Annie","Hernandez",
                    "Dorothy","Murphy",
                    "Alice","Howard");

$lastNameCollection = array("Ruth","Jackson",
                    "Debra","Allen",
                    "Gerald","Harris",
                    "Raymond","Carter",
                    "Jacqueline","Torres",
                    "Joseph","Nelson",
                    "Carlos","Sanchez",
                    "Ralph","Clark",
                    "Jean","Alexander",
                    "Stephen","Roberts",
                    "Eric","Long",
                    "Amanda","Scott",
                    "Teresa","Diaz",
                    "Wanda","Thomas");

$newFirstName = $firstNameCollection[rand(0, count($firstNameCollection)-1)];
$newMiddleName = $middleNameCollection[rand(0, count($middleNameCollection)-1)];
$newLastName = $lastNameCollection[rand(0, count($lastNameCollection)-1)];

$fullNameCollection = array();
$fullNameCollection[] = $newFirstName." ".$newMiddleName." ".$newLastName;

如果我用“echo $ fullNameCollection”打印它，它只会给我一个名字......那么..我怎样才能制作20.000个名字？谢谢。

Answer 1

使用for循环

$fullNameCollection = array();
for($i = 0; $i < 20000;$i++) {
    $newFirstName = $firstNameCollection[rand(0, count($firstNameCollection)-1)];
    $newMiddleName = $middleNameCollection[rand(0, count($middleNameCollection)-1)];
    $newLastName = $lastNameCollection[rand(0, count($lastNameCollection)-1)];

    $fullNameCollection[] = $newFirstName." ".$newMiddleName." ".$newLastName;
}

如果您想输出所有名称，例如

foreach($fullNameCollection as $name) {
    echo $name;
}

只有唯一名称

$fullNameCollection = array();
while(count($fullNameCollection) <= 20000) {
    $newFirstName = $firstNameCollection[rand(0, count($firstNameCollection)-1)];
    $newMiddleName = $middleNameCollection[rand(0, count($middleNameCollection)-1)];
    $newLastName = $lastNameCollection[rand(0, count($lastNameCollection)-1)];


    $name = $newFirstName." ".$newMiddleName." ".$newLastName;

    if(!in_array($name, $fullNameCollection)) {
         $fullNameCollection[] = $name;
    }
}

注意：如果没有足够的可能性用于唯一名称，则此循环可以是无限的。如果你想要所有组合，最好不要使用随机函数

嗯，我猜你的代码周围需要for循环？

$fullNameCollection = array();

for ($x = 0; $x < 20000; $x++) {
    $newFirstName = $firstNameCollection[rand(0, count($firstNameCollection)-1)];
    $newMiddleName = $middleNameCollection[rand(0, count($middleNameCollection)-1)];
    $newLastName = $lastNameCollection[rand(0, count($lastNameCollection)-1)];


    $fullNameCollection[$x] = $newFirstName." ".$newMiddleName." ".$newLastName;
}

使用数组生成随机名称
