For even more powerful string handling and manipulating functions take a look at the Perl compatible regular expression functions. For working with multibyte character encodings, take a look at the Multibyte String functions The function expects to be given a string containing an English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00: 00: 00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.
Each parameter of this function uses the default time zone unless a time When serializing objects, PHP will attempt to call the member function sleep() prior to serialization. This is to allow the object to do any last minute cleanup, etc. prior to being serialized. This is to allow the object to do any last PHP Manual; Function Reference; File System Related Extensions; Filesystem; Filesystem Functions; some sites requiring a valid useragent string when using fopen can easily be resolved by setting the useragent string in the PHP.
INI file. If you do not have access to the PHP. INI file, then the use of There are no limitations on the values the string can be composed of; in particular, bytes with value 0 (NUL bytes) are allowed anywhere in the string (however, a few functions, said in this manual not to be binary safe, may hand off the strings to libraries that ignore data after a NUL byte.
) Since this function only accepts integer timestamps the u format character is only useful when using the dateformat() function with user based timestamps created with datecreate(). timestamp The optional timestamp parameter is an integer Unix timestamp that defaults to the current local time if a timestamp is not given. Mar 10, 2008 I created this function a while back to save on having to combine onto all the params passed into a sprintf.
it works literally the same as the sprintf other than that it doesn't require you to escape your inputs. striptags Strip HTML and PHP tags from a string stripcslashes Unquote string quoted with addcslashes stripos Find the position of the first occurrence of a caseinsensitive substring in a string But if the START parm is equal to the LENGTH of the string, then you'll get an empty string (PHP 7) or FALSE (prior to PHP 7).
An example of this would be 'substr(" x"1, 1) which would return either an empty string or FALSE. The character set must be set either at the server level, or with the API function mysqlsetcharset() for it to affect See the concepts section on character sets for more information.
Instead of detailing all the possible string functions you can use, we'll just give you a brief list. (There's loads of them! ) There's an example of how to use each string function, if you click on the links below. There are more details for string casting and conversion in the Strings section of the PHP manual, including special handling for booleans and nulls.
