help with explode

[jaay]

Hi, I am new to php and stuck with a problem, need some help

 

I have a field in mysql table that stores tags separated by comma. Now I am using the explode function to separate the tags and display them separtely ... it works fine if theres a space after the comma .... that is like, tag1, tag2, tag3 etc... but if the user doesnt leave a space after the comma ..it doesnt work .. say for example, tag1, tag2,tag3 ..in this case only tag1 and tag2 gets displayed not tag3 .... what am i doing wrong here? here's my code ..

 

$stags = explode(", ", $a);

$result = count($stags);

 

for($n = 0; $n < $result; $n++)

{

$stags = explode (",", $a);

echo trim($stags [$n]);

}

Try this:

<?php
$tags = "tag1, tag2,tag3";
$etags = explode(',',$tags);
foreach ($etags as $tag) {
echo trim($tag);
}

$stags = explode(", ", $a); has a space in it. Trim removes additional spacing. Just make it

$stags = explode(",", $a);

Alternative to buddski's code.

 

$tags = "tag1, tag2,tag3";
$etags = explode(',',$tags);
$etags = array_map('trim', $etags);

It worked! Thanks everyone for the help.
