A regular expression can be considered as a powerful wildcard (Universal matching symbol ). Most people should be familiar with wildcards. For example, when we see an expression such as "Sams", any string starting with SAMs in a text string can match this expression. Regular Expressions provide a matching mechanism that is more powerful than such wildcards, more complex control rules, and more functional. This article will give an overview of the classes provided by the. NET Framework that sup

Occasionally, I would like to review the various information of the 17th jolt award, but every time I want to see it, I always need to search for it very hard. It's a little troublesome, so I need to back up it.

For example, if we want to create an SQL command to insert the name 'Reilly into the table, we must replace the "'" In 'Reilly with the two connected. The best way to do this is to create a helper method to complete the repla

and compiled every time an SQL command is executed. This may make you think that using a PreparedStatement object is faster than using a Statement object. However, my tests show that this is not the case in client software. Therefore, in SQL operations with time restrictions, unless SQL commands are processed in batches, we should consider using the Statement object.In addition, using the Statement object makes it easier to write dynamic SQL commands, because we can connect strings together to

variable names are not parsed in the following string: $name = ' Fred '; $str = ' Hello, $name '; single-quoted enclosed in single quotation marks. Echo $str; Hello, $name The only escape sequence available in a string enclosed in single quotation marks is \ ' (enclose the single quotation mark in a string enclosed in single quotation marks), \ \ (place a backslash in a string enclosed in single quotation marks). Any other backslashes can only be interpreted as a backslash: $name = ' Tim o\ '

(). addslashes-referencing strings with backslashes Description String Addslashes (String $str) Returns a string that is preceded by a backslash in order for the database query statement to be preceded by some characters. These characters are single quotes ('), double quotation marks ("), backslashes (\), and NUL (the NULL character). An example of using addslashes () is when you want to enter data into the database. For example, the name O ' Reilly

'Reilly into the database, which requires escaping. Most databases use \ as the escape character: O \ 'Reilly. In this way, the data can be put into the database without inserting additional \. When the PHP command magic_quotes_sybase is set to on, it means that when 'is inserted,' is used for escape. Addslashes escapes special characters in SQL statements, including ('), ("), (), (NUL, this function is us
