Unable to insert data.

Question

var_dump($num); The result is boolean false
You can insert it by executing the sql statement directly in the database. php.ini expands normally.

Answer 1

Actually, there is no problem. I just missed a field. Look at what you wrote, are there any details that you didn’t notice

Answer 2

What do you think is the reason? This is really strange.

Answer 3

You didn't find the root cause. I have the same problem and I didn't find the root cause either. CamelCase variable naming has no effect at all. Mine cannot be inserted normally if the $createTime parameter is added. If the content of this field is not inserted, it can be inserted normally

Answer 4

Camel case naming is not supported. Variable names can only be in lowercase. For example, it is not possible to write $dbtype as $dbType. What is the reason?

Answer 5

$dsn="{$dbtype}:host={$host};dbname={$dbname}";

Finally found the reason. There can't be any spaces in it. It doesn't work if there are spaces.

Answer 6
