Question

我试图使用php，

在mysql中存储一些数据

$description="Hi, My Name is Nilesh C. Narvekar, I am a Dog Trainer since last 12 years experience in this field. also I am participate my trained dogs in DOG SHOWS (in Obedience class as well as Breed Shows) So Please Contact me on My Cell no. 9920 338835 I teach HEEL (walk), STAY, SIT, SHAKE HAND (Right / Left), DOWN, RECALL, Retrieve (Ball / Any Article) SALUTE, REST, SLEEP, ROLL, SPEAK, ATTACK, SEARCHING, PERSONAL PROTECTION, GUARD AND Much & More I use Positive Reinforcement training System i.e. (first I give more Exercise for reducing Dogs energy level then doing more practice with dogs and then after I use some treats for giving Dogs attention and concentration to me in training session)";

$sql = "INSERT INTO pet_trainer(name, description, address, city, area, contact, email, timing, latitude, longitude)
                            VALUES 
                            (
                            '"$name"',
                            '"$description"',
                            '"$address"',
                            '"$city"',                       
                            '"$area"',
                            '"$contact"',
                            '"$email"',
                            '"$timing"',
                            '$lat',
                            '$long'
                            )";

当我尝试执行此操作时，由于描述较大，$ sql变量不会显示它显示的所有详细信息。

INSERT INTO pet_trainer(image, name, description, address, city, area, contact, email, timing, latitude, longitude)
                            VALUES 
                            ('',
                            'Nilesh C. Narvekar',
                            '\'Hi, My Name is Nilesh C. Narvekar, I am a Dog Trainer since last 12 years experience in this field. also I am participate my trained dogs in DOG SHOWS (in Obedience class as well as Breed Shows) So Please Contact me on My Cell no. 9920 338835 I teach HEEL (walk), STAY, SIT, SHAKE HAND (Right / Left), DOWN, RECALL, Retrieve (Ball / Any Article) SALUTE, REST, SLEEP, ROLL, SPEAK, ATTACK, SEARCHING, PERSONAL PROTECTION, GUARD AND Much & More I use Positive Reinforcement training System i.e. (first I give more Exercise for reducing Dogs energy level then doing more practice with dogs and then after I use some treats for giving Dogs attention and concentration to me in training session)\'',
                            'Andheri  Mumbai',
                            'Mumbai',

当我减小$ description的大小时，$ sql将获取所有数据。是php变量有一些限制存储字符串字符？那我该怎么办？请帮我。谢谢。

Answer 1

转到phpMyAdmin，转到您的表pet_trainer并查看description列设置（点击phpMyAdmin中的表名，然后点击结构）

您有几个选择：
- text
- varchar(max length of content)
如果您只想存储原始文本或html文本，我建议您使用文本作为pet_trainer列的类型设置。
其次，检查第一个变量的值，不再显示（在你的例子中：$contact）如果这个变量的值有问题（即特殊字符或类似的东西），它可能会阻止SQL查询的进一步索引）
最后，因为整个问题基本上与SQL系统无关，但只是一个不存储简单字符串全长的php变量可能会让你产生问题。停止寻找SQL查询修复程序，因为您没有SQL问题。

您显示/解释它的方式，您在长字符串中连接变量时出错，这对PHP来说应该不是问题。（以上仅在您使用PHP而不是在SQL服务器上打印变量时才计算）

如果您希望我帮助您或其他任何人，那么（在我上次描述的情况下）向我们展示您如何声明变量以及它们的值是什么......

您更新了问题，我继续更新我的答案:)

编辑：对您的评论说你使用了varchar（10000），如果你想要一个长内容字符串，请不要这样做，使用文本，这就是它的用途：）

Answer 2

yeahh。

我用单行编写所有参数/值，现在它正常工作。

$ sql =“INSERT INTO pet_trainer（姓名，描述，地址，城市，地区，联系方式，电子邮件，时间，纬度，经度）VALUES（'”$ name“'，'”$ description“'，'”$地址“'，'”$ city“'，'”$ area“'，'”$ contact“'，'”$ email“'，'”$ timing“'，'$ lat'，'$ long'）” ;

php变量确实存储了大量的文本内容
