for cases like where number would be -0.01.</td></tr><tr><td> </td><td><a href='function.parse-str.html'>parse_str</a></td><td>Usage of parse_str without a second parameter
now emits an E_DEPRECATED notice.</td></tr></tbody><tbody class="gen-changelog v7-2-0"><tr><td>7.1.0</td><td><a href='function.str-shuffle.html'>str_shuffle</a></td><td>The internal randomization algorithm has been changed to use the Mersenne Twister Random Number Generator instead of the libc rand function.</td></tr><tr><td> </td><td><a href='function.stripos.html'>stripos</a></td><td>Support for negative offsets has been added.</td></tr><tr><td> </td><td><a href='function.strpos.html'>strpos</a></td><td>Support for negative offsets has been added.</td></tr><tr><td> </td><td><a href='function.substr-count.html'>substr_count</a></td><td>Support for negative offsets and lengths has been added.
