Php 使用array if else语句防止表单重复
我有一个类似RNG滚动表的代码，所以当您输入用户名时，它将发送用户数据和页面加载时生成的秘密隐藏号（RNG） 但我有一个问题，在30-35号座位上滚动时，RNG的数量有时会重复，而且耗时 我试图用if-else语句和带有array\u push函数的数组来解决这个问题，让已经输入的数字存储在数组中，然后用if语句检查数字是否在数组中，如果它存储了，则必须返回“reroll”随机数，否则继续 这是我的索引代码：Php 使用array if else语句防止表单重复,php,mysql,arrays,if-statement,Php,Mysql,Arrays,If Statement,我有一个类似RNG滚动表的代码，所以当您输入用户名时，它将发送用户数据和页面加载时生成的秘密隐藏号（RNG） 但我有一个问题，在30-35号座位上滚动时，RNG的数量有时会重复，而且耗时 我试图用if-else语句和带有array\u push函数的数组来解决这个问题，让已经输入的数字存储在数组中，然后用if语句检查数字是否在数组中，如果它存储了，则必须返回“reroll”随机数，否则继续 这是我的索引代码： <!DOCTYPE html> <html> <head

为什么不确保秘密隐藏号码（RNG）始终是唯一的，而不是首先解决您造成的问题？使用数字1…35使这非常困难。如果加载的页面超过35页怎么办？使用1…35有特殊原因吗？你叫他们座位？我真的不知道这段代码应该做什么…对不起，如果检测到新表单输入，unique是否会自动添加/生成？或者它采用了我的表单，该表单有$u POST['nomer']（rng）？通常您会等到表单提交后再分配唯一id。那么我如何分配它？只需创建并设置列，但如何使其成为由数字1-35组成的整数？thxy您通常会为此使用一个自动递增列：这样您将保证它是唯一的值。请注意，mysql扩展不是最好使用的，请使用mysqli或PDO，请参阅：与其解决您首先造成的问题，为什么不确保秘密隐藏号（RNG）始终是唯一的？使用数字1…35使这非常困难。如果加载的页面超过35页怎么办？使用1…35有特殊原因吗？你叫他们座位？我真的不知道这段代码应该做什么…对不起，如果检测到新表单输入，unique是否会自动添加/生成？或者它采用了我的表单，该表单有$u POST['nomer']（rng）？通常您会等到表单提交后再分配唯一id。那么我如何分配它？只需创建并设置列，但如何使其成为由数字1-35组成的整数？thxy您通常会为此使用一个自动递增列：这样您将保证它是唯一的值。请注意，mysql扩展不是最好使用的，请使用mysqli或PDO，请参阅：
