This can be useful in several different situations, especially if you need to send headers to the browser after your script has begun outputting data. The Output Control functions do not affect headers sent using <span class="function"><a href="function.header.html" class="function">header()</a></span> or <span class="function"><a href="function.setcookie.html" class="function">setcookie()</a></span>, only functions such as <span class="function"><a href="function.echo.html" class="function">echo</a></span> and data between blocks of PHP code. </p> </div><hr /><div class="manualnavbar" style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="book.outcontrol.html">Output Control</a></div> <div class="next" style="text-align: right; float: right;"><a href="outcontrol.setup.html">Installing/Configuring</a></div> <div class="up"><a href="book.outcontrol.html">Output Control</a></div> <div class="home"><a href="index.html">PHP Manual</a></div> </div></body></html>
