Online PHP syntax checker / validator [closed]

Question

Could someone refer me to an online PHP validator? It would be of much help.

Thanks in advance!

What kind of validation do you want ? – Atworth

I would like one that would find the errors in my PHP script, display at which line the error is at, and possibly explain the error. – Oller

Perhaps you could write your own? Just need to use php -l [filename] to parse the php file, and not execute it. – Hairstyle

Why an online validator instead of using an IDE such as NetBeans or ZendStudio? I think a really inquisitive web developer would use a desktop validator instead of an online validator, I would not trust the later to be more reliable... – Squiggle

@Hairstyle Could you explain in more detail what you just said? – Oller

@Hairstyle is php -l [filename] a parsing as part of php's compiler? – Dextrosinistral

Answer 1

To expand on my comment.

You can validate on the command line using php -l [filename], which does a syntax check only (lint). This will depend on your php.ini error settings, so you can edit you php.ini or set the error_reporting in the script.

Here's an example of the output when run on a file containing:

<?php
echo no quotes or semicolon

Results in:

PHP Parse error:  syntax error, unexpected T_STRING, expecting ',' or ';' in badfile.php on line 2

Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in badfile.php on line 2

Errors parsing badfile.php

I suggested you build your own validator.

A simple page that allows you to upload a php file. It takes the uploaded file runs it through php -l and echos the output.

Note: this is not a security risk it does not execute the file, just checks for syntax errors.

Here's a really basic example of creating your own:

<?php
if (isset($_FILES['file'])) {
    echo '<pre>';
    passthru('php -l '.$_FILES['file']['tmp_name']);
    echo '</pre>';
}
?>
<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file"/>
    <input type="submit"/>
</form>

It being a security risk or not depends on where the file was uploaded. – Groom

If you don't have php in your $PATH variable you can cd to the directory where php.exe exists and call php.exe -l C:\path\to\file.php. – Dextrosinistral

Here's one more for you that not only performs the php -l check for you, but also does some secondary analysis for mistakes that would not be considered invalid (e.g. declaring a variable with a double equal sign).
