This presumes a space and not just whitespace. What does the adaptation
look like if you account for space, tab, newline, carriage return? >:)
That said, if we were to only match on a space character:
<?php
$text = "The nimble fox jumped over the river.";
if( ($splitPoint = strpos( $text, ' ' )) !== false )
{
$word = substr( $text, 0, $splitPoint );
$rest = substr( $text, $splitPoint + 1 );
}
else
{
$word = $text;
$rest = '';
}
echo "[$word] [$rest]\n";
?>
But then yours is more concise (though not as concise as the regular
expression). This is just faster. Depends on what you want ;)
Cheers,
Rob.
