I PHP-versioner tidligere end 4.3.3 eksisterede der en fejl n<>r man
|
|
|
|
|
|
brugte arrays b<>de som <parameter>search</parameter>- og <parameter>replace</parameter>
|
|
|
|
|
|
parametre hvilket for<6F>rsagede at tomme
|
|
|
|
|
|
<parameter>search</parameter>-indekser blev ignoreret, uden at f<>lge med
|
|
|
|
|
|
i hvor pointeren var placeret i <parameter>replace</parameter>-arrayet.
|
|
|
|
|
|
Dette er blevet rettet i <literal>PHP 4.3.3</literal>, alle scripts der
|
|
|
|
|
|
hvilket p<> denne fejl skulle fjerne tomme s<>gev<65>rdier tidligere for at
|
|
|
|
|
|
f<> funktionen til at opf<70>re sig som den b<>r.
