title: Why does "php --version" return "Segmentation fault (core dumped)" after installing phpLDAPadmin?
body: <p>I'm running Apache 2.4 on FreeBSD (FAMP stack) and had Wordpress successfully hosting a website. However I recently tried to install phpLDAPadmin in order to manage an LDAP server and now whenever Apache is running, any page on my site displays the following:</p>
  
  <blockquote>
    <p>Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /usr/local/www/apache24/data/wp-includes/wp-db.php:1643 Stack trace: #0 /usr/local/www/apache24/data/wp-includes/wp-db.php(639): wpdb->db_connect() #1 /usr/local/www/apache24/data/wp-includes/load.php(427): wpdb->__construct('user', 'pass', 'wordpressdb', 'localhost') #2 /usr/local/www/apache24/data/wp-settings.php(120): require_wp_db() #3 /usr/local/www/apache24/data/wp-config.php(92): require_once('/usr/local/www/...') #4 /usr/local/www/apache24/data/wp-load.php(37): require_once('/usr/local/www/...') #5 /usr/local/www/apache24/data/wp-blog-header.php(13): require_once('/usr/local/www/...') #6 /usr/local/www/apache24/data/index.php(17): require('/usr/local/www/...') #7 {main} thrown in /usr/local/www/apache24/data/wp-includes/wp-db.php on line 1643</p>
    
    <p>The site is experiencing technical difficulties.</p>
  </blockquote>
  
  <p>Furthermore, when I went to check the version of php, this happens:</p>
  
  <pre><code># php --version
  Segmentation fault (core dumped)
  </code></pre>
  
  <p>I read that it can happen when upgrading php from 5.x to 7.x, but unless installing phpLDAPadmin performed an upgrade, I believe I have had php 7.2 all along. I was able to see that the man page for php shows version 7.2.21. While the problem does seem to be related to php, I haven't been able to figure out exactly what is going on. It seems extremely odd that I can't even check the php version in the command line. </p>
  
  <p>I have tried restarting, as well as updating via freebsd-update and portsnap followed by a reinstall, not to mention various configuration changes to php.ini, wp-config.php and httpd.conf.</p>
  
  <p>====Edit====</p>
  
  <p>I ran <code>pkg upgrade -f</code> which made the following changes:</p>
