Instalação/Configuração

This happened to me also with PHP 5.4.1Copying the offending DLL everywhere didn't worket, and I don't have Postgres installed in the server, but also planned to use PHP against different Postgres versions, so the only solution I found that worked was to put in httpd.conf a line like this:LoadFile "C:/Program Files/PostgreSQL/8.4/bin/libpq.dll" but refering to the libpq.dll that comes bundled with PHP, like this:LoadFile "C:/php/libpq.dll" After that it worked fine to me.(c) https://stackoverflow.com/users/1373641/dayron-armas-peñafrom: https://stackoverflow.com/questions/551734/php-not-loading-php-pgsql-dll-on-windows/10439560#10439560

If you get a message like this: "Php Startup: Unable to load dynamic library 'C:\php\ext\php_pgsql.dll"1. In the Configuration File alter the order of the libraries "php_exif.dll" and "php_mbstring.dll", in such a way that is called first the library "php_mbstring.dll"2. Copy all the libraries in the folder "bin" of your installation of PostgreSQL and paste them into the root folder of Windows3. Uncomment the line "extension=php_pgsql.dll"4. Now you should see on the page generated by "phpinfo()" section of PostgreSQL

Unable to load dynamic library 'C:\\php\\ext\\php_pgsql.dll' - The specified module could not be found.another solution:copy libpq.dll/all files from zip (if you have php from installer)add to httpd.conf:#BEGIN PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALLPHPIniDir "c:/PHP/"Loadfile "C:\php\php5ts.dll"Loadfile "C:\php\libpq.dll"LoadModule php5_module "c:/PHP/php5apache2_2.dll"#END PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALLAddHandler application/x-httpd-php .phpAddHandler application/x-httpd-php-source .phps(in php.ini default: extension_dir ="c:\PHP\ext" )if it doesn't work add c:\php (php path) to your windows path (and restart)tested on php5.2.8 + apache2.2.3

If you get this error on Windows:Unable to load dynamic library 'C:/php/ext\\php_pgsql.dll' - The specified module could not be found.Try downloading the PostgreSQL binaries-no-install archive from http://www.postgresql.org/ftp/binary/v8.3.5/win32/ (replace 8.3.5 with the latest stable version) and copy these DLLs to C:/WINDOWS/system32/ :comerr32.dllgssapi32.dllk5sprt32.dllkrb5_32.dlllibeay32.dlllibiconv2.dlllibintl3.dlllibpq.dllssleay32.dll
