Killing spaces in strings

[sorenchr]

Hi there, im having a bit of trouble with strings consisting of nothing else but blank spaces.

Since im using a rather large function, i've decided not to bother you with the more complex details and just make a little example that illustrates my problem.

 

Im looking for a function that will target and delete strings containing nothing more but spaces (1 or more), i've tried the following:

 

$string = " ";
str_replace(' ', '', $string);

if(empty($string)) {

echo "empty!";

}

else {

echo "spacy, i say";

}

 

Im absolutely out of ideas of what to do, since this obviously doesn't work. Anybody got a solution?

<?php
$string = " ";
$string = trim(str_replace(' ', '', $string));

if(empty($string)) {

echo "empty!";

}

else {

echo "spacy, i say";

}
?>

Sir, i say sir, you are a genius

I don't think you even need the str_replace.  Try just trim().

Thanks, as a side note.

str_replace(' ', '', $string)

is not required when using trim(). So use:

<?php
$string = " ";
$string = trim($string);

if(empty($string)) {

echo "empty!";

}

else {

echo "spacy, i say";

}
?>

I thought trim only got rid of spaces at the beginning or end, not in the middle?

If the string is all spaces, it doesn't matter.

If you need to remove absolutely all spaces keep your str_replace().
