How to list all the items dynamically in an explode array

[justin7410]

Hey guys,

 

so i am retrieving data from my database and have called on a certain variable..

 

this variable is called $personality_traits and is containing a string with all the tags (honest,go getter,lazy,humble,etc..)

 

each persons profile is showing these traits as to what is being stored per their own ID.

 

so one individual profile would show

profile 1 Traits : Happy, Organized, Honest. Brave

profile 2 Traits : Quiet, Conservative, Shy, Smart

profile 3 Traits : Honest, Smart, Go getter, 

Now my issue:

 

i am now trying to break this variables string into parts , so that i can echo the tags individually , and create hrefs from them accordingly.

 

When i use the explode() this works for me and separates each tag into an index inside an array

while ($row = mysql_fetch_assoc($links)) { 

extract($row); 

$user_traits  // data from field `user_traits` FROM `database` 
$traits = explode( ',' , $user_traits ); 
echo $user_traits; 
print_r($traits);

Which results in; ( for 1 profile example)

positive,warm,fun
Array ( [0] => positive [1] => warm [2] => fun )

My Question;

 

How can i now list all the indices in this array for each user , as if i were inputting $user_traits ?

 

i cant just type  

echo $traits[0]; 
echo $traits[1]; 
echo $traits[2];

since each profile has a different amount of variables to be defined, some have only 2 traits, while others might have 4,5 or even 6.

 

I am assuming there is a way to do this using a mysql command , but is there anyway PHP wise to solve this problem ?

 

any ideas or suggestions would be much appreciated, this is a feature i definitely want to have showing for my users.

Such a simple yet helpful answer . Thank you Jessica, i just did not think this quite through enough

 

for the answer was simply:

while ($row = mysql_fetch_assoc($links)) { 
extract($row); 

$user_traits // data from field `user_traits` FROM `database` 
$traits = explode( ',' , $user_traits );
echo $user_traits;
print_r($traits); 

foreach ($traits as $trait){
     echo '<a href="#">' .$trait .'</a>';
}
