How do I track php file execution through the console?

Question

update: actually my problem had nothing to do with this snippet from blockquote down there. I learned how to debug PHP, and I found several errors, but I’m not even going to enter here in each of them because it’s not the case... So even though I solved it differently, Guilherme’s comments and response helped me to understand some concepts, and how I think it can help other users, I decided not to remove the question and accept the answer.

-.-

Update: I found the problem, which is in this excerpt:

 <blockquote>
        <strong> <em>RECURSO DE REVISTA. [...] RESCISÃO DO CONTRATO DE TRABALHO - NULIDADE - AUSÊNCIA DE ASSISTÊNCIA SINDICAL.
        O objetivo da assistência sindical no pedido de demissão decorre da consagração do princípio da
        irrenunciabilidade dos direitos trabalhistas. Retrata o art. 477, § 1º, da CLT, norma cogente, que condiciona
        o pedido de demissão e a quitação do contrato de trabalho firmado pelo empregado cuja relação jurídica vigorou
        por mais de um ano, à assistência perante o Sindicato. Nesse sentido, a formalidade determinada pela norma, se
        não cumprida, torna nulo o ato. Incumbe ao empregador o cumprimento da formalidade prevista no art. 477, § 1º,
        da CLT, sob pena de não se convalidar o pedido de demissão, quando não houver a homologação, nos
        termos previstos na norma. Precedentes. Recurso de revista conhecido e provido. [...]</em></strong> (TST   PROCESSO Nº
        TST-RR-256-42.2010.5.02.0088, 6ª Turma, Relatora Desembargadora Convocada CILENE FERREIRA AMARO SANTOS,
        Data de Julgamento: 10/12/2014 - grifos nossos)
    </blockquote>

And the problem seems to be inside the text itself, I thought it was the use of brackets, but I think it’s not even, I tried to escape with \ and it didn’t work.

In fact, this other part is also giving the same problem (I have tested only one part, without the other, and gives the same problem):

<p>
            <?php echo $motivdesligjust; ?>
            <?php echo "<br>"; ?>
        </p>
        <p>
            <?php echo $motivdesligind; ?>
            </p>

I can’t call variables inside tags <p></p>?

/update

I’m having a problem here in running a php file, which uses include to include other files, and I can’t figure out the cause. It seems to be an infinite loop, but I’m not using for, while, nothing, just call the variables escaping the html, and use a if or another...

The file keeps running in the browser and not for more, there is the message "Waiting for localhost", and after that no other php file can run before I reset phpstorm.

So I was wondering if you have any commands for me to follow the execution, and why it keeps running in this infinite loop.

It is a strange mistake because are several files included by include, and if I remove the first 3 for example, it works, and the same happens if I leave only the first three, but I’ve already reviewed the files and I can’t find the problem.

Answer 1

As this question in Soen there are some tools for this, such as:

monolog

Installing with Composer:

$ composer require monolog/monolog

Basic example of use:

<?php

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$log = new Logger('name');
$log->pushHandler(new StreamHandler('pasta/seu-arquivo-de-log.log', Logger::WARNING));

// Adiciona gravações para o log
$log->addWarning('Foo');
$log->addError('Bar');

phptrace

(i’m not sure, but I think it only works with FPM, apache2handler which is more common in windows with apache might not work)

1. Extract the extension:

   tar -zxf phptrace-{version}.tar.gz
   cd phptrace-{version}
   

2. Compile the extension

   cd extension
   {php_bin_dir}/phpize
   ./configure --with-php-config={php_bin_dir}/php-config
   make
   make install
   

   (in case it is windows and mingw will probably have to use mingw32-make)

3. Copy the compiled extension to the php extension folder and edit php.ini

   extension=trace.so
   

4. Compile the commandtool

   cd cmdtool
   make
   

5. Testing if installation is ok:

   php -r 'for ($i = 0; $i < 100; $i++) usleep(10000);' & ./phptrace -p $!
