Prior to PHP 7.1.0, rewrite variables set by output_add_rewrite_var shared an output buffer with transparent session id support (see session.trans_sid_tags).
	output_reset_rewrite_vars	Before PHP 7.1.0, rewrite vars set by output_add_rewrite_var use the same Session module trans sid output buffer. Since PHP 7.1.0, dedicated output buffer is used and output_reset_rewrite_vars only removes rewrite vars defined by output_add_rewrite_var.
	pcntl_signal	As of PHP 7.1.0 the handler callback is given a second argument containing the siginfo of the specific signal. This data is only supplied if the operating system has the siginfo_t structure. If the OS does not implement siginfo_t NULL is supplied.

7.0.0	assert	assert 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_numeric	Le stringhe nella notazione esadecimale (per esempio 0xf4c3b00c) non sono più considerate come stringhe numeriche, ovvero is_numeric ora restituisce false.

	list	Le espressioni list non possono più essere completamente vuote.
	list	Le stringhe non possono più essere spacchettate.
	set_exception_handler	Il tipo di parametro passato in exception_handler è cambiato da Exception a Throwable

6	error_reporting	E_STRICT è diventata parte di E_ALL.
5.6.0	curl_setopt	CURLOPT_SAFE_UPLOAD è ora true per impostazione predefinita.
	curl_setopt	Rimosso CURLOPT_CLOSEPOLICY e i suoi valori associati.
5.5.0	curl_setopt	Aggiunta la risorsa cURL come primo argomento alla callback CURLOPT_PROGRESSFUNCTION.
	curl_setopt	Introdotto CURLOPT_SHARE.
	empty	empty ora supporta le espressioni, piuttosto che solo variabili.
	set_exception_handler	In precedenza, se veniva passato null allora questa funzione restituiva true. Restituisce il gestore precedente da PHP 5.5.0.
5.4.8	assert	È stato aggiunto il parametro description. La description è anche ora fornita ad una funzione di callback in modalità ASSERT_CALLBACK come quarto parametro.
5.4.7	curl_getinfo	Introdotte CURLINFO_PRIMARY_IP, CURLINFO_PRIMARY_PORT, CURLINFO_LOCAL_IP e CURLINFO_LOCAL_PORT.
5.4.0	array_multisort	Le costanti SORT_NATURAL e SORT_FLAG_CASE sonon state aggiunte a array1_sort_flags come flag di tipo.
	empty	Il controllo su offset non numerici di stringhe restituisce true.
	iconv	Da 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.
	isset	Il controllo su offset di stringhe non numerici ora restituisce false.
5.3.9	is_a	Aggiunto il parametro allow_string
	is_subclass_of	Aggiunto il parametro allow_string
5.3.7	curl_getinfo	Introdotto CURLINFO_REDIRECT_URL.
	is_subclass_of	Aggiunto il supporto per class_name per funzionare come le interfacce
5.3.4	sleep	Prima di PHP 5.3.4 in Windows, sleep ritorna sempre null quando è eseguita, a prescindere dal fatto che sia stata interrotta o meno.
5.3.0	array_multisort	La costante SORT_LOCALE_STRING è stata aggiunta a array1_sort_flags come flag di tipo.
	curl_setopt	Introdotto CURLOPT_PROGRESSFUNCTION.
	get_class	null 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_vars	Questa funzione ora restituisce null se object non è un oggetto. In precedenza veniva restituito false.
	is_a	Questa funzione non è più deprecata, e quindi non genererà warning E_STRICT.
	setlocale	Questa funzione emette un avviso E_DEPRECATED se una stringa è passata al parametro category invece che una delle costanti LC_*.
	strtotime	Prima 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.
	strtotime	Prima di PHP 5.3.0, 24:00 non era un formato valido e strtotime restituiva false.
5.2.10	curl_setopt	Introdotto CURLOPT_PROTOCOLS, e CURLOPT_REDIR_PROTOCOLS.
5.2.7	error_log	Aggiunto il valore 4 per message_type
	strtotime	In 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.
5.2.5	addcslashes	Sono state aggiunte le sequenze di escape \v e \f.
5.2.4	curl_getinfo	Introdotto CURLINFO_PRIVATE.
5.2.0	error_reporting	Inserita E_RECOVERABLE_ERROR.

5.1.0	curl_setopt	Introdotto CURLOPT_AUTOREFERER, CURLOPT_BINARYTRANSFER, CURLOPT_FTPSSLAUTH, CURLOPT_PROXYAUTH, e CURLOPT_TIMECONDITION.
	get_parent_class	Se venisse chiamata senza parametro fuori dall'oggetto, questa funzione dovrebbe restituire null con un avvertimento, ma ora restituisce false.
	gmdate	Il 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).
	intval	Genera E_NOTICE e restituisce 1, quando un oggetto è passato a var.
	sha1_file	Modificata 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_count	Aggiunto il parametro charlist
	strtotime	Ora restituisce false in caso di fallimento, invece di -1.
	strtotime	Ora emette gli errori time zone E_STRICT e E_NOTICE
	var_export	Possibilità di esportare classi e array contenenti classi utilizzando il metodo magico __set_state().
5.0.3	get_class_vars	get_class_vars restituirà solo le proprietà che possono essere accedute dall'ambito corrente.
	is_subclass_of	Si potrebbe anche specificare il parametro object come una stringa (il nome della classe)
5.0.2	get_class_vars	Chiamando 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.
	strtotime	In 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.
5.0.1	get_class_vars	Chiamando get_class_vars verranno esposte tutte le proprietà, come quando si converte un oggetto in una classe.
5.0.0	curl_setopt	Introdotto CURLOPT_FTP_USE_EPRT, CURLOPT_NOSIGNAL, CURLOPT_UNRESTRICTED_AUTH, CURLOPT_BUFFERSIZE, CURLOPT_HTTPAUTH, CURLOPT_PROXYPORT, CURLOPT_PROXYTYPE, CURLOPT_SSLCERTTYPE, e CURLOPT_HTTP200ALIASES.
	error_reporting	Inserita E_STRICT (non fa parte di E_ALL).
	is_a	Questa funzione venne deprecata in favore dell'operatore instanceof. La chiamata a questa funzione risulterà in un warning E_STRICT.
	opendir	path accetta il wrapper URL ftp:// .
	sha1_file	Aggiunto il parametro raw_output.
	strtotime	I microsecondi hanno cominciato ad essere consentiti, ma sono ignorati.
	usleep	Questa funzione ora funziona anche sui sistemi Windows.
