When the INSERT operation fails, I want to record the error information in another file, such as the error time and cause.

In the PHP language, for digital characters and numbers how to participate in the operation, in specific cases will be determined, for example: echo "3+4+5"; Results: 3+4+5. Because it is treated as a string. When echo1+2+ "3+4+5", it is treated as an expression. This involves the problem of different data type operations in PHP. Data of different data types when

3. Pre-increment/pre-increment operators: two operators borrowed from C. Example:
The Code is as follows:
Var iNum = 10;Console. log (++ iNum); // outpus 11 same as iNum = iNum + 1Console. log (iNum); // outpus 11Console. log (-- iNum); // outpus 10 same as iNum = iNum-1Console. log (iNum); // outpus 10
