 DOMCharacterData::afterCalling this method on a node without a parent is now a no-op to align the behaviour with the DOM specification. Previously this threw a DOMException with code DOM_HIERARCHY_REQUEST_ERR.

7.0.0assertassert è ora un costrutto del linguaggio e non una funzione. assertion ora può essere usata come un'espressione. Il secondo parametro è ora interpretato o come un exception (se viene passato un oggettoThrowable), o come la description supportato da PHP 5.4.8 in poi.
 is_numericLe stringhe nella notazione esadecimale (per esempio 0xf4c3b00c) non sono più considerate come stringhe numeriche, ovvero is_numeric ora restituisce false.

 listLe stringhe non possono più essere spacchettate.
 set_exception_handlerIl tipo di parametro passato in exception_handler è cambiato da Exception a Throwable

 curl_setoptIntrodotto CURLOPT_SHARE.
 emptyempty ora supporta le espressioni, piuttosto che solo variabili.
 set_exception_handlerIn precedenza, se veniva passato null allora questa funzione restituiva true. Restituisce il gestore precedente da PHP 5.5.0.
5.4.8assertÈ stato aggiunto il parametro description. La description è anche ora fornita ad una funzione di callback in modalità ASSERT_CALLBACK come quarto parametro.
5.4.7curl_getinfoIntrodotte CURLINFO_PRIMARY_IP, CURLINFO_PRIMARY_PORT, CURLINFO_LOCAL_IP e CURLINFO_LOCAL_PORT.

 emptyIl controllo su offset non numerici di stringhe restituisce true.
 iconvDa questa versione, la funzione restituisce false in caso di caratteri illegali, a meno che non venga specificato //IGNORE nel charset di output. Prima, questa funzione restituiva una stringa di output parziale.

5.3.0array_multisortLa costante SORT_LOCALE_STRING è stata aggiunta a array1_sort_flags come flag di tipo.
 curl_setoptIntrodotto CURLOPT_PROGRESSFUNCTION.
 get_classnull è diventato il valore di default per object, quindi passare null a object ora ha lo stesso risultato di non passare nessun valore.
 get_object_varsQuesta funzione ora restituisce null se object non è un oggetto. In precedenza veniva restituito false.
 is_aQuesta funzione non è più deprecata, e quindi non genererà warning E_STRICT.
 setlocaleQuesta funzione emette un avviso E_DEPRECATED se una stringa è passata al parametro category invece che una delle costanti LC_*.
 strtotimePrima di PHP 5.3.0, i formati del tempo relativi forniti all'argomento time di strtotime come this week, previous week, last week, e next week erano interpretati per intendere un periodo di 7 giorni relativo alla data/ora corrente, invece di un periodo settimanale di Monday a Sunday.
 strtotimePrima di PHP 5.3.0, 24:00 non era un formato valido e strtotime restituiva false.
5.2.10curl_setoptIntrodotto CURLOPT_PROTOCOLS, e CURLOPT_REDIR_PROTOCOLS.
5.2.7error_logAggiunto il valore 4 per message_type
 strtotimeIn PHP 5 precedente a 5.2.7, richiedere una data occorrenza di un dato giorno della settimana in un mese dove il giorno della settimana era il primo giorno del mese aggiungerebbe in modo scorretto una settimana al timestamp restituito. Questo è stato corretto in 5.2.7 e nelle versioni successive.
5.2.5addcslashesSono state aggiunte le sequenze di escape \v e \f.
 debug_backtraceAggiunto il parametro opzionale provide_object.

5.1.0curl_setoptIntrodotto CURLOPT_AUTOREFERER, CURLOPT_BINARYTRANSFER, CURLOPT_FTPSSLAUTH, CURLOPT_PROXYAUTH, e CURLOPT_TIMECONDITION.
 get_parent_classSe venisse chiamata senza parametro fuori dall'oggetto, questa funzione dovrebbe restituire null con un avvertimento, ma ora restituisce false.
 gmdateIl range valido di un timestamp è tipicamente da Venerdì, 13 Dicembre 1901 20:45:54 GMT a Martedì, 19 Gennaio 2038 03:14:07 GMT. (Queste sono le date che corrispondono ai valori minimo e massimo per un intero a 32-bit con il segno). Comunque, prima di PHP 5.1.0 questo range era limitato da 01-01-1970 a 01-19-2038 su alcuni sistemi (per esempio Windows).
 intvalGenera E_NOTICE e restituisce 1, quando un oggetto è passato a var.
 sha1_fileModificata la funzione per utilizzare lr API streams. Ciò significa che si può utlizzare la funzione con i vari warppers, tipo sha1_file('http://example.com/..')
 str_word_countAggiunto il parametro charlist
 strtotimeOra restituisce false in caso di fallimento, invece di -1.
 strtotimeOra emette gli errori time zone E_STRICT e E_NOTICE
 var_exportPossibilità di esportare classi e array contenenti classi utilizzando il metodo magico __set_state().
5.0.3get_class_varsget_class_vars restituirà solo le proprietà che possono essere accedute dall'ambito corrente.
 is_subclass_ofSi potrebbe anche specificare il parametro object come una stringa (il nome della classe)
5.0.2get_class_varsChiamando get_class_vars verranno esposte tutte le proprietà come array, a differenza dei precedenti comportamenti dove le proprietà protected e private erano prefissate con byte nul.
 strtotimeIn PHP 5 fino a 5.0.2, "now" e altri tempi relativi sono erroneamente calcolati a partire dalla mezzanotte di oggi. Questo differisce dalle altre versioni in cui viene correttamente calcolato dal tempo corrente.
5.0.1get_class_varsChiamando get_class_vars verranno esposte tutte le proprietà, come quando si converte un oggetto in una classe.
5.0.0curl_setoptIntrodotto CURLOPT_FTP_USE_EPRT, CURLOPT_NOSIGNAL, CURLOPT_UNRESTRICTED_AUTH, CURLOPT_BUFFERSIZE, CURLOPT_HTTPAUTH, CURLOPT_PROXYPORT, CURLOPT_PROXYTYPE, CURLOPT_SSLCERTTYPE, e CURLOPT_HTTP200ALIASES.
 error_reportingInserita E_STRICT (non fa parte di E_ALL).
 is_aQuesta funzione venne deprecata in favore dell'operatore instanceof. La chiamata a questa funzione risulterà in un warning E_STRICT.
 opendirpath accetta il wrapper URL ftp:// .
 sha1_fileAggiunto il parametro raw_output.
 strtotimeI microsecondi hanno cominciato ad essere consentiti, ma sono ignorati.
 usleepQuesta funzione ora funziona anche sui sistemi Windows.
