PHP Form POST Question

[pwright2]

I have a script that loops through all POST variables with this type of loop:

foreach($_POST as $parm => $val)
{
$parm_string = "$parm=$val|";
}
//more stuff here

The form that posts to this page has text boxes on it. If the user types "015" for one of the values in the text box, $val is automatically converted to 15 in the $parm_string variable.

Any suggestions to keep the "015" from the text box?

I am using:
php5-5.2.10-29.2
apache2-mod_php5-5.2.10-29.2

Wild guess... put quotes around $parm and $val on the foreach line.

Good luck.

Doing
foreach($_POST as "$parm" => "$val")
{
//code here
}

Results in a php error on the page. Is there another way I can loop through all $_POST variables? There are many forms that submit to this page and I need to parse each key/value pair of the $_POST array. I wonder if the foreach assignment is automatically converting $val to the datatype it believes will fit best.

Try viewing the output before you use your foreach and then alter afterward:

vardump($_POST) #or something like that... maybe var_dump)

Good luck.

Try
foreach($_POST as $parm => $val)
{
$parm_string = sprint('%s=%s', $parm, $val);
}

The var_dump($_POST) helped. It did show that it is a string in the array. For some reason, when it is in $val, it is converted to an integer. This seemed to work though:

foreach($_POST as $parm => $val)
{
$val = (string) $val;
$parm_string = "$parm=$val|";
}
