Comparison operators, as their name implies, allow you to compare two values.  vs [\n1234] string(4) "1234" string(5) "\n1234" EQUAL !
You may also be interested in viewing the type comparison tables, as they show examples of various type related comparisons.  vs [1234 ] string(4) "1234" string(5) "1234 " DIFFERENT !
We will discuss this in more detail in the following examples.
Summary: in this tutorial, you will learn how to rename tables using My SQL RENAME TABLE statement and ALTER TABLE statement.
Because business requirements change, we need to rename the current table to a new one to better reflect the new situation.
If you compare a number with a string or the comparison involves numerical strings, then each string is converted to a number and the comparison performed numerically. The type conversion does not take place when the comparison is === or !  vs [1234\n] string(4) "1234" string(5) "1234\n" DIFFERENT !
== as this involves comparing the type as well as the value. note: the behavior below is documented in the appendix K about type comparisons, but since it is somewhat buried i thought i should raise it here for people since it threw me for a loop until i figured it out to clarify a tricky point about the == comparison operator when dealing with strings and numbers:('some string' == 0) returns TRUEhowever, ('123' == 0) returns FALSEalso note that ((int) 'some string') returns 0and ((int) '123') returns 123the behavior makes senes but you must be careful when comparing strings to numbers, e.g.
My SQL provides us with a very useful statement that changes the name of one or more tables.
