eliminating redundant spaces from a string.

[phpbuilderpro]

Hi,

what is the best way to remove redundant spaces from a string without using reqular expressions?

consider this string:

pizza1            pizza2 pizza3 pizza4

Thanks

Was

pizza1 pizza2 pizza3 pizza4

supposed to be

pizza1  pizza2  pizza3  pizza4

Anyway, your only good option to do this in a generic fashion is with regexp. Otherwise you'd have to

# on every iteration, check the string for occurence of more than one
# consecutive white space
while(strpos('  ', $str) !== false) {
	# replace each sequence of two whitespaces with one whitespace
	$str = str_replace('  ', ' ', $str);
}

And the reason the above is silly, assume this is your input

$str = '1                                                                                   2';

And besides, the regexp approach is so simple

$p = '#[ ]+#';
$str = preg_replace($p, ' ', $str);
