How to chop extra spaces from a string?

Anon

Can anyone tell me a way of chopping extra space characters from a string.
e.g. I want to convert the following string
"This sentence has too many spaces in between"

"This sentence has too many spaces in between"

Can I use eregi_replace to do the task ? if not is there any in-built function ?

Thanks.

You can use trim();

e.g.

$sen = "Blabla___blabla"

echo "$sen"; outputs Blablablabla where = one space

if you do trim($sen); you get Blabla_blabla

good luck, Arni

I thought trim() removes spaces from start and end of a string Only.

So trim is of no use to me.
My whole purpose is to Explode the string using One Space Sharacter.

$allparts = explode(" " , $input_string) ;

This works fine if there is Only one Sapce Character in between the string, but fails for multiple space characters in between.
I don't get all the components in the right order in $allparts array.

Any other solution ?
Thanks.

Ok, so this will probably do for you:

$str = ereg_replace (' +', ' ', $str);

where $str = "bla__bla"; and is space

ok?

Good luck, Arni

Thank you very much, Arni for that handy tip of ereg_replace. It worked !

Well, if your ultimate goal is to get "words" into an array, and you have no other use for the space-trimmed string, just substitute split() for explode() and do it all in one step:

$allparts = split('  +' , $input_string); // that's one space followed by +

split() differs from explode() in using a regex rather than a simple string to specify how to split the string.
