(excuse my english)
When I try to use explode to know if a string contains many words, I noticed this :
<?php
$sentence= " word ";
$array = explode($sentence);
var_dump($array);
?>
return this :
array(4) {
[0]=> string(0) ""
[1]=> string(0) ""
[2]=> string(4) "word"
[3]=> string(0) ""
}
So, "explode" didn't keep the delimiter but counts it. You have to use
trim($sentence) to count words in a sentence. ^v^
