I want to extract the first word of a variable from a string. For example, take this input:

<?php $myvalue = 'Test me more'; ?>

The resultant output should be Test, which is the first word of the input. How can I do this?

There is a string function (strtok) which can be used to split a string into smaller strings (tokens) based on some separator(s). For the purposes of this thread, the first word (defined as anything before the first space character) of Test me more can be obtained by tokenizing the string on the space character.

<?php
$value = "Test me more";
echo strtok($value, " "); // Test
?>

For more details and examples, see the strtok PHP manual page.
