PHP Interview Questions

Q   |   QA

If you want to create a table, you can run the CREATE TABLE statement as shown in the following sample script:

include "mysql_connection.php";

$sql = "CREATE TABLE ggl_links ("
. ", url VARCHAR(80) NOT NULL"
. ", notes VARCHAR(1024)"
. ", counts INTEGER"
. ", time TIMESTAMP DEFAULT sysdate()"
. ")";
if (mysql_query($sql, $con)) {
print("Table ggl_links created.n");
} else {
print("Table creation failed.n");


Remember that mysql_query() returns TRUE/FALSE on CREATE statements. If you run this script, you will get something like this:
Table ggl_links created

You can encrypt a password with the following Mysql>SET PASSWORD=PASSWORD("Password");

You can use the MySQL PASSWORD() function to encrypt username and password. For example,
INSERT into user (password, ...) VALUES (PASSWORD($password”)), ...);

Just like in C++, put an ampersand in front of it, like $a = &$b 

string strstr ( string haystack, string needle ) returns part of haystack string from the first occurrence of needle to the end of haystack. This function is case-sensitive.

stristr() is idential to strstr() except that it is case insensitive. 

When the original if was followed by : and then the code block without braces.
