274

Here are some sweet code snippets for getting various types of server information. Includes more functions for getting and/or checking various types of WordPress, PHP, and SQL data. Strictly plug-&-play for quick reference and copy/paste usage.

WordPress: Check the database table prefix:

// check table prefix
function shapeSpace_check_wp_prefix() {
	
    if ($GLOBALS['table_prefix'] === 'wp_') {
        echo 'fail';
    } else {
        echo 'pass';
    }
    
}

WordPress: Check the wp-config.php file:

// check wp-config.php
function shapeSpace_check_wp_config($path) {
	
	if (!is_writable($path)) {
		return 'pass';
	}
	
	if (!function_exists('file') || !function_exists('file_get_contents') || !function_exists('file_put_contents')) {
		return 'pass';
	} else {
		return 'fail';
	}
	
}

PHP: Check XML support

// check php xml support
function shapeSpace_check_php_xml() {
	
	if (is_callable('xml_parser_create')) {
		return 'pass';
	} else {
		return 'fail';
	}

}

PHP: Check IPTC support

// check php iptc support
function shapeSpace_check_php_iptc() {
	
	if (is_callable('iptcparse')) {
		return 'pass';
	} else {
		return 'fail';
	}
	
}

PHP: Check EXIF support

// check php exif support
function shapeSpace_check_php_exif() {
	
	if (is_callable('exif_read_data')) {
		// substr(phpversion('exif'), 0, 4)
		return 'pass';
	} else {
		return 'fail';
	}
	
}

SQL: Get SQL version

// get sql version
function shapeSpace_get_sql_version() {
	
	global $wpdb;
	
	return $wpdb->get_var('SELECT VERSION() AS version');
	
}

SQL: Get SQL info

// get sql info
function shapeSpace_get_sql_info() {
	
	global $wpdb;
	
	$sqlvar = $wpdb->get_results("SHOW VARIABLES LIKE 'sql_mode'");
	
	$sqlmode = 'n/a';
	
	if (is_array($sqlvar)) {
		$sqlmode = $sqlvar[0]->Value;
	}
	
	return $sqlmode;
