The latest version of PHP can be downloaded from Softpedia
PHP, an HTML-embedded scripting language with syntax borrowed from C, Java, and Perl, with a couple of unique PHP-specific features thrown in, has been updated to version 5.5.14.The PHP 5.x branch includes a new OOP model based on the Zend Engine, a new extension for improved MySQL support, built-in native support for SQLite, and much more.
“Please, note that this release also fixes a backward compatibility issue that has been detected in the PHP 5.5.13 release. Still, the fix in PHP 5.5.14 may break some very rare situations. As this tiny compatibility break involves security, and as security is our primary concern, we had to fix it. This concerns bug 67072,” said the developers in the official announcement.
According to the changelog, a number of built-in web-server segfaults that occurred on startup have been fixed, closures now correctly captures the late bound class (static::), a BC break introduced in a previous version has been fixed, the constructor can now be called twice, the DateTime no longer truncates fractions of a second, and a buffer overflow in locale_get_display_name and uloc_getDisplayName has been corrected.
