Verify if a string contains x number of characters

[nydeveloper]

I'm trying to create an if statement that checks a string and determines if it contains x number of characters.  For example, if $test has 3 characters then <action>.

 

The second part of my question involves the <action>.  What I'm looking to do is append a specific character set to the beginning of said string.

 

For example:

 

$test = 'abc'

 

If $test consists of 3 characters then

{

      $test = '1234' appended to the beginning of the original value of $test

}

else

{

do nothing

}

 

In this example, the final value of $test would be '1234abc'

 

 

Thanks in advance for any guidance here.

use strlen for your condition and a dot . to concatenate strings.
