Creating arrays with explode()

[Adem]

Hello,
mails are separated by commas, some have spaces but some don’t
How can I fix this problem

$str = ‘mail,mail,mail, mail, mail, mail, mail’;

print_r (explode(", ",$str));

Output:
Array ( [0] => mail,mail,mail [1] => mail [2] => mail [3] => mail [4] => mail )

mails are separated by comma

Explode the data on the commas.

some have spaces but some don’t

Then trim the array of data after you have exploded it.

You can do both of these in a single statement -

$result = array_map('trim', explode(',',$str));
