How to fix parse and syntax errors in WordPress

WordPress parse errors usually occur when PHP parser faces troubles interpreting some piece code. In WordPress similar errors happen after incorrect code modifications. In this tutorial we will learn how to fix these WordPress issues. I will also provide some examples on how to avoid such problems and build your code properly so that PHP can correctly process the code and return the expected output.

WordPress code examples

In the begging let’s look at the following standard parse error :

Parse error: syntax error, unexpected T_STRING in /home/a41686868/public_html/index.php on line 9

As you can see the error specifically refers to exact line and also give information on what is the exact problem. The easiest way to fix syntax errors is to revert the recent changes and try to modify them in way that would allow PHP to understand and process the code.

If you are new to WordPress development field, you may wish to use some code tool that has auto complete options. This way you can be sure that at least partially the code will be correct. This is because tools such as Notepad++ would take care for the proper starting and ending of the lines. It also takes cares to single and double quotes combinations.

When it comes to proper syntax, I would like to give one example of incorrectly structured line that uses both single and double quotes:

echo "<input type="Radio" name="wpp" value="point">"."Some text<br>";

That line would definitely generate parse error, because the syntax is not correct. To avoid problem with our PHP code integrated into WordPress, we will need to modify it by escaping the double quotes which would break the execution. Here is how the code should be modified:

echo "<input type=\"Radio\" name=\"wpp\" value=\"point\">"."Some text<br>";

Another possible solution would be to use single and double quotes separately. Here is another example that would keep PHP from throwing parse errors:

echo "<input type='Radio' name='wpp' value='point'>"."Some text<br>";

Parse and syntax PHP errors in WordPress – quick conclusion:
When you see some parse error in your browser, the first thing you have to check is your code. If you did not modify any piece of code, then you should check the plugins or themes you recently installed. Another course of action is to check your hosting environment and look for recent changes in PHP configuration. Compatibility issue could also cause some problems, so if that is the case, you may put on test your website and its extensions and see if they are compatible with the PHP version you are currently using.

What usually causes PHP parse and syntax errors?
