When you are sure your script is perfectly working, you can get rid of warning and notices like this: Put this line at the beginning of your PHP script:

<pre><code>error_reporting(E_ERROR);
</code></pre>

Before that, when working on your script, I would advise you to properly debug your script so that all notice or warning disappear one by one.

So you should first set it as verbose as possible with:

<pre><code>error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
</code></pre>

UPDATE: how to log errors instead of displaying them

As suggested in the comments, the better solution is to log errors into a file so only the PHP developer sees the error messages, not the users.

A possible implementation is via the .htaccess file, useful if you don't have access to the php.ini file (<a href="http://perishablepress.com/press/2008/01/14/advanced-php-error-handling-via-htaccess/" rel="nofollow noreferrer">source</a>).

<pre><code># Suppress PHP errors
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0

# Enable PHP error logging
php_flag log_errors on
php_value error_log /home/path/public_html/domain/PHP_errors.log

# Prevent access to PHP error log
&lt;Files PHP_errors.log&gt;
 Order allow,deny
 Deny from all
 Satisfy All
&lt;/Files&gt;
</code></pre>

blocks|key|1204868|text|您可以在php.ini中设置所需的错误报告类型，也可以通过在脚本上使用error_reporting()函数来设置。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1204869|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You can set the type of error reporting you need in php.ini or by using the error_reporting() function on top of your script.

Always show errors on a testing server. Never show errors on a production server.

Write a script to determine whether the page is on a local, testing, or live server, and set $state to "local", "testing", or "live". Then:

<pre><code>if( $state == "local" || $state == "testing" )
{
 ini_set( "display_errors", "1" );
 error_reporting( E_ALL &amp; ~E_NOTICE );
}
else
{
 error_reporting( 0 );
}

If you can't get to your php.ini file for some reason, disable errors to stdout (<code>display_errors</code>) in a .htaccess file in any directory by adding the following line:

<code>php_flag display_errors off</code>

additionally, you can add error logging to a file:

<code>php_flag log_errors on</code>

I am getting expected notices and warnings and would like to turn them off in my PHP file. The error is:

<pre><code>Warning: fsockopen()
</code></pre>

And the notice are:

<pre><code>Notice: A non well formed numeric value encountered in
</code></pre>

I am planning to use cron for this PHP script and do not want to get any errors or notices logged anywhere.

Turn off warnings and errors on PHP and MySQL

测试服务

服务器

我收到了预期的通知和警告，并希望在我的PHP文件中将其关闭。错误是：Warning: fsockopen()通知如下：Notice: A non well formed numeric value encountered in我计划对这个PHP脚本使用cron，不想在任何地方记录任何错误或通知。
