Php if variable length is equal to

You need to check if the length of $ message is 7 characters or less, if so, do step A, if not, do step B. Is this the correct syntax? I think I'm doing something wrong?

<?php if (strlen($message) <= 7) { echo $actiona; } else { echo $actionb; } ?>

It's good. For example, run the following command:

 <?php $message = "Hello there!"; if (strlen($message) <= 7){ echo "It is less than or equal to 7 characters."; } else { echo "It is greater than 7 characters."; } ?>

He will print: "This is more than 7 characters."

You can also use the shorthand PHP if / even using ternary operators (? :).

For example, instead of:

 <?php if (strlen($message) <= 7) { echo $actiona; } else { echo $actionb; } ?>

You can write this as:

 <?php echo strlen($message) <= 7 ? $actiona : $actionb; ?>

See How to use if / else shorthand? for information about the ternary operator.

What error messages do you get?

I would check that when you put $message in front of the hand, you will not miss it or use the wrong capital letter (bearing in mind that php is sensitive cAsE).

This is normal.

But you have to use long php tags (short tags can be disabled and often happen):

 <?php // ... PHP code ?>

(closing tag is optional if your file contains only PHP)

I found this ISSET "trick" around www, I don’t remember where. try running the script first as follows, then uncomment the second line of $ message = .. to write a line of a different length.

 <?php $actiona="ACTIONA"; $actionb="ACTIONB"; $message="1234567"; //$message="12345678";//try to comment /uncomment these if (!isset($message{7})) { echo $actiona; } else { echo $actionb; } ?>

And of course

 <?php $actiona="ACTIONA"; $actionb="ACTIONB"; $message="1234567";//try to comment /uncomment these //$message="12345678"; echo !isset($message{7}) ? $actiona : $actionb; ?>

Good luck We all love Php !!!!
