What is wampserver?
Wampis the first line of windows?apache=mysqland PHP. static files (such as pure HTML with a suffix of .html) can be run on the operating system, but script files written in PHP are not allowed. The operating system does not understand what it is saying, so a translation is required, this translation is the PHP running environment Wamp, which is used to parse the PHP script. Wampserver is an open-source PHP suite built locally. After installing this suite, we simulate a PHP environment locally, so that we can install and use WordPress locally.
Download wampserver
The latest version of wampserver is 2.2d at present, but we should not go to the latest version, because the new versions of PHP and MySQL are relatively high, and the servers in reality cannot be upgraded so quickly, A higher MySQL version may even cause joomla, a famous CMS system, to be unable to be installed. Therefore, we recommend a safe version of wampserver 2.0g. Click here to download it.

Remove the previous # and restart wampserver.♦Configure PHP. INI left-click the wampserver System icon and select php> PHP. INI, will use NotePad to open the following items, and modify their value post_max_size-to allow the maximum value of the data transmitted through post, change to the value that you think is appropriate, if the setting is too small, this will cause the upload of large images or videos to fail.
Upload_max_filesize-maximum value that can be uploaded. This value is usually smaller than post_max_size.
Max_execution_time-maximum time allowed for script execution. If this time is exceeded, a timeout error is reported. The default value is 30 seconds.
Max_input_time-How long does a script wait for input data?
Memory_limit-memory limit. When creating a thumbnail, it will consume a large amount of memory. If the memory is insufficient, the following error fatal error: allowed memory size of 134217728 bytes will be reported.
Exhausted (tried to allocate 1099 bytes) inerror_reporting = e_all &~ E_notice-the default value is e_all. It is recommended to change it to e_all &~ E_notice, that is, no notice error is displayed, and all others show error log settings.

However, this is not the case. Opening the address starting with http: // With fopen may time out or report an error indicating that the file does not exist, another important step is to modify the host file. This is not a Wamp problem. It is a Windows problem. The host file is located (assuming that your system is located on disk C)

C: \ windows \ system32 \ drivers \ etc \ hosts

Remove the marker before 127.0.0.1 to use the file starting with http.
