//Instructions

//

//Functions use any of these parameters:

//    $section    : section name

//    $key(s)        : key(s) name

//    $value        : value

//    $default    : default value if $key can not be found

//    $file_name    : name of the file

//    

//Available functions:

//

//    write_key($section, $key, $value, $file_name)

//        Writes a key and its value under a certain section.

//        It creates the file if it doesn't exist.

//

//    write_section($section, $keys, $file_name)

//        Writes an entire section and its keys.

//        It creates the file if it doesn't exist.

//        $keys must be a single dimension array, structured as: $keys[$key]=$value.

//        eg:    $keys["Key1"]="Value1";

//            $keys["Key2"]="Value2";

//            ...

//        eg:    $keys = array( "Key1" => "Value1", "Key2" => "Value2");

//

//    delete_key($section, $key, $file_name)

//        Deletes a key

//

//    delete_section($section, $file_name)

//        Deletes an entire section.

//

//    read_key($section, $key, $default, $file_name)

//        Reads a certain value.

//        It returns $default if the value or the file do not exist.

//

//    read_section($section, $default, $file_name)

//        Reads an entire section.

//        It returns a single dimension array, structured as: $keys[$key]=$value.

//        It returns $default if the section or the file do not exist.

//        eg: If $keys is the returned value, you can show values with the following code:

//            foreach ($keys as $key=>$value)

//                echo "$key => $value<br>";

My code

PHP Code:

---

<?
include("inifunc.php");
$value = read_key("Index", "Loads", "default value", "test.txt");
PRINT("$value");
?>

---

test.txt

Code:

---

[Index]
Loads=1

---

Problem:
Nothing happens!

ahem... are you forgetting some "squiggly brackets"?

PHP Code:

---

function read_key($section, $key, $default, $file_name) 

{ 

    if (!file_exists($file_name)) 

        return($default); 

     

    $content = read_ini($file_name);

look at the if... are you missing something?
