Si l'option <parameter>search_value</parameter> est spécifiée,
|
|
seules les clés ayant cette valeur seront retournées.
|
|
Sinon, toutes les clés de <parameter>input</parameter> sont
|
|
retournées.

|
Depuis &php; 5, vous pouvez utiliser le paramètre <parameter>strict</parameter>
|
|
pour une comparaison incluant le type (===).
