this is what i have that doesnt work any help whold be aprischiated

<?php
function assign($var_array){

echo $var $content;
}

i get "dafghc" as my result (separate the variables with a period)

 

<?php
function assign($var_array)
{
    foreach ($var_array as $var => $content) {
        echo $var . $content;
    }
}

assign(array('d' => 'a', 'f' => 'g', 'h' => 'c'));
?>

}

assign(array('d' => 'a', 'f' => 'g', 'h' => 'c'));
?>

 

that fixed it but can you explain why thous  variables need to be seperated with a period it doesnt seem like it whould  be needed please forgive me i am quite new

The period is the concatenation operator.

 

You can not say

<?php
$a = "this is";
$b = "a string";
echo $a $b;
?>

You can do

<?php
$a = "this is";
$b = "a string";
echo $a . $b;
?>

or

<?php
$a = "this is";
$b = "a string";
echo "$a $b";
?>

or

<?php
$a = "this is";
$b = "a string";
echo $a . ' ' . $b;
?>

i have another question not sure if i should start a new post or not

 

is it possible to pass a loop to another function to print it maybe my example will help

 

<?php
class test
{
var $testvar;

function assign($var_array,$cac)
{
foreach ($var_array AS $var => $content)
{
$this->testvar = $var . $content;
}

}

function output()
{
echo $this->testvar;
}
}
$tpl = new test();

$tpl->assign(array('d' => 'a',
	 'f' => 'g',
	 'h' => 'c')," mmmmn");

$tpl->output();
?>

Have you tried your code?

 

yes it only prints out one value not all them

[Barand]

change

 

$this->testvar = $var . $content;

 

to

 

$this->testvar .= $var . $content;

[JustinB]

change

 

$this->testvar = $var . $content;

 

to

 

$this->testvar .= $var . $content;

String Operators

 

There are two string operators. The first is the concatenation operator ('.'), which returns the concatenation of its right and left arguments. The second is the concatenating assignment operator ('.='), which appends the argument on the right side to the argument on the left side. Please read Assignment Operators for more information.

 

<?php
$a = "Hello ";
$b = $a . "World!"; // now $b contains "Hello World!"

$a = "Hello ";
$a .= "World!";     // now $a contains "Hello World!"
?>
