Apache on CentOS – Fix GMP Extension Recognition Issues

apache-2.4centos7php7

I have this error in running a webapp on a Centos 7, PHP 7.2 server:

PHP Fatal error: Call to undefined function gmp_init() in … a.php on line 2

If I call it from cmd line it works:

b:3

Code:

<?php
$b = gmp_init( 3, 16 );
echo "b:" . $b;
?>

How can I tell apache to load the extension?

thanks

Try installing "php-gmp" on your server using Yum like #yum install php-gmp. It will pull all the available php-gmp version from the repo. Then enable it in your php.ini file like "extension=php_gmp.so".

Mysql – CentOS 7 thesqli works on php apache but not on php-cli

As pointed out by Michael Hampton (thanks) in the comment, there were two php installations in the server. I have arrived at two different solutions based on specific need:

For php-cli:

In the .bash_profile, the following line is added
alias php="/usr/bin/php"

For running PHP from java servlet (as command):

Use

String[] commands = {"bash", "-c", "/usr/bin/php myphpfile.php arg01 arg02"};
File dir = new File("<my-php-file-directory>");
try{
Process process;
process = Runtime.getRuntime().exec(commands, null, dir);
process.waitFor();
....
....
}

Thats all

php -modules in the terminal gives the desired output with mysqli.

Linux – Install and enable exif

If php.ini contents is like this:

1   extension=php_mbstring.dll
2   extension=php_exif.dll

make sure in your PHP installation ext directory php_exif.dll is present.

If it's not there, get it from here.
