Récupérer le nom d'une variable

[Argorate]

@Anthor, Allwise :
je vous montre le test que j'ai fais:

Code PHP :

<?php 

function vname(&$var, $scope=false, $prefix='unique', $suffix='value')

  {

    if($scope) $vals = $scope;

    else      $vals = $GLOBALS;

    $old = $var;

    $var = $new = $prefix.rand().$suffix;

    $vname = FALSE;

    foreach($vals as $key => $val) {

      if($val === $new) $vname = $key;

    }

    $var = $old;

    return $vname;

  }

  

function test(&$variable)

{

    $tab[vname($variable)] = $variable;

    return $tab;

}

$toto=2;

$tab = test($toto);

var_dump($tab);
