Apply Trim on Whole Array?

[chaseman]

Is there a way to apply the function trim() on a whole array, instead of applying it to the individual input fields one by one?

 

Here's the code:

$blurb1_title = array ( 
$_POST['blurb1_title1'], 
$_POST['blurb1_title2'],
$_POST['blurb1_title3'],
$_POST['blurb1_title4'],
$_POST['blurb1_title5']
);

$blurb2_title = array ( 
$_POST['blurb2_title1'], 
$_POST['blurb2_title2'],
$_POST['blurb2_title3'],
$_POST['blurb2_title4'],
$_POST['blurb2_title5']
);

$blurb3_title = array ( 
$_POST['blurb3_title1'], 
$_POST['blurb3_title2'],
$_POST['blurb3_title3'],
$_POST['blurb3_title4'],
$_POST['blurb3_title5']
);

 

All those $_POST variables are input fields, and I would like to apply trim() to them so the spaces get removed.

 

Is there an efficient way to do it without having to apply it all individually, if yes, what would be the correct syntax?

yeah you could use a foreach() loop to pull out each key and trim each one...not sure if thats what you're looking for

Oops I accidentally posted my reply to the other thread. Well here's the reply again.

 

Thanks PFM,

 

I tried to implement it but I was not able to do so, I tried the following:

 

function blurb_titles ($all_titles) {

trim($all_titles);

}

array_walk ($blurb2_title, 'blurb_titles');

 

Which I added below the array list.

 

But this would only break my script.

First, he said to use array_map() not array_walk() and you need to run the array through trim:

 

$blurb2_title = array_map('trim', $blurb2_title);

[chaseman]

What I tried was

 

array_map (trim(), $blurb2_title);

 

Didn't think that your version will work too, but now that I look at it it seems obvious. Trim is no different than any other function, it's just global.

 

 

Thanks abra!
