[RESOLVED] print_r to variable?

v3nt

hello!

i've got this;
print_r($_POST);

which works fine.

but how can i turn the data into a variable with linebreaks so i can just go

echo $postedData;

i just want to include the posted data into an email script which can only accept variables or strings...

many thanks, Dan.

$_POST is an array, so loop over it.

i tried that but there's only one of each variable and i didn't get anywhere.

are you saying that;
$_POST[1]
should print the 2nd field and value in the array?
surname => jones

No. $POST is an associative array. If you want to print the element with the key of 'surname', then print $POST['surname']. If you want to loop over the array use a foreach loop.

thanks!

tried again with;

foreach($_POST as $item){
$postedData .="". $item."\n";
}
echo $postedData;

which prints out the field value, but i'd like to print out the fieldname to if possible?

laserlight

$postedData = '';
foreach($_POST as $key => $item){
    $postedData .= $key . ': ' . $item . "\n";
}
echo $postedData;

v3nt

ahhh!

many thanks laserlight!

Don't forget to mark this thread resolved (if it is) using the option on the Thread Tools menu above.

Not that print_r() is necessarily a good way to do what you want, but I do want to point out that if you set it's optional 2nd parameter to true, it will return the string instead of outputting it:

$var = print_r($_POST, true);

thanks!
