Question

what does this function means

function entre2v2($text,$marqueurDebutLien,$marqueurFinLien)

{

$ar0=explode($marqueurDebutLien, $text);
$ar1=explode($marqueurFinLien, $ar0[1]);
$ar=trim($ar1[0]);

}

in above code $text refers to a text files content,which is obtained by the following code from a form post:

$text=file_get_contents($_POST['file']);

can anybody please describe about the mentioned php function?i dont understand what these two variable means

$marqueurFinLien
$marqueurDebutLien

according to first answer,I tried .But it shows error.

Warning: Missing argument 3 for entre2v2(), called in C:\xampp\htdocs\php\test.php on line 5 and defined in C:\xampp\htdocs\php\test.php on line 13

Notice: Undefined variable: marqueurFinLien in C:\xampp\htdocs\php\test.php on line 18

Notice: Undefined offset: 1 in C:\xampp\htdocs\php\test.php on line 18

Warning: explode() [function.explode]: Empty delimiter in C:\xampp\htdocs\php\test.php on line 18

when I used the follwing:

<?

$text=file_get_contents('http://localhost/php/w.txt');

$name=entre2v2($text,"DB_USER', ',');");


echo($name);
echo("<br>");



function entre2v2($text,$marqueurDebutLien,$marqueurFinLien)

{

$ar0=explode($marqueurDebutLien, $text);
$ar1=explode($marqueurFinLien, $ar0[1]);
$ar=trim($ar1[0]);
return $ar;
}

?>

Answer 1

The function appears to return the text between the $marqueurDebutLien and $marqueurFinLien strings from the input $text.

e.g.

$text = "abcdefghijklmnop";
$result = entre2v2($text, 'd', 'lmn'); // will return 'efghijk'
