When coding with PHP, you often use two symbols for the equal sign. The symbols are ‘==’ and ‘=’. However, they do not mean the same thing. When you declare variables or use mySQL queries, you always use’=’. But, when you use conditions, you must use’==’.
Here is an error that may be displayed when you use the incorrect ‘=’sign.
Parse error: syntax error, unexpected ‘=’ in /home/user/public_html/folder/file.php on line 100
The example below shows a simple error and how to fix it.
if($var=22) { echo "Hello World";} // code should be should be if($var==22) { echo "Hello world"; }
