If you ever need to adjust or change the default user agent that PHP accesses pages with (http and ftp wrappers) because either the default PHP user agent was blocked (“PHP”) or you wrote a bot with PHP and wish to customize it, you can do so easily with a php directive called “user_agent”<\/a>. Note that 3rd party ways (such as cURL) are not affected by this setting.<\/strong><\/p>\n

To set it, you can use the following function:<\/p>\n

<?php<\/span><\/span><\/code><\/p>\n

function <\/span>set_php_user_agent<\/span>(<\/span>$useragent <\/span>= <\/span>‘PHP’<\/span>)\u00a0{
\n<\/span>$u <\/span>= <\/span>strval<\/span>(<\/span>$useragent<\/span>);
\nif(<\/span>ini_set<\/span>(<\/span>‘user_agent’<\/span>,<\/span>$u<\/span>)\u00a0=== <\/span>false<\/span>)\u00a0{
\n<\/span>$r <\/span>= <\/span>false<\/span>;
\n}\u00a0else\u00a0{
\n<\/span>$r <\/span>= <\/span>true<\/span>;
\n}
\nreturn <\/span>$r<\/span>;
\n}<\/span><\/p>\n

\/\/\u00a0Example:
\n<\/span>set_php_user_agent<\/span>(<\/span>‘TestAgent\/1.0\u00a0(http:\/\/www.example.com\/testagent\/)’<\/span>);<\/span><\/p>\n

To get you started, here are some user agents for you to use or test:<\/p>\n
