Evaluation of PHP code

[mattsches]

I'm struggling to evaluate PHP code. I suppose the correct command would be php -r or php --run.

---
patat:
  eval:
    php:
      command: php -r
      fragment: true
      replace: false
      wrap: code
...

# PHP Example

```php
$foo = get_defined_constants();

results in:

# PHP Example

                                    
    $foo = get_defined_constants(); 
                                    

                                                          
     php -r : exit code 1                                 
    Error in argument 1, char 2: no argument for option r 
                                                          

This is probably because of command line variable substitution done by shell as mentioned in the note here (scroll down to the -r --run option).

Unfortunately, my shell foo is not strong enough to resolve this in the context of patat (or on the command line). Any ideas?

There's probably many ways to do this... One solution would be to wrap the input (cat -) in <? ... ?> and pipe that to PHP:

---
patat:
  eval:
    php:
      command: '(echo "<?"; cat -; echo "?>") | php'
...

# Hello world

Some PHP:

```php
print("Hello, world!");
```

Sorry, it's not working for me. The output is:

# Code Example

                            
    print("Hello, world!"); 
                            

                              
    <?                        
    print("Hello, world!");?> 

I wonder if there's a way to replace double quotes with single quotes like so: php -r '$foo = get_defined_constants(); var_dump($foo);'? I can't find a way to achieve this.

It's probably not even a patat issue, but more of a general bash issue I guess.

I figured out that my PHP installation has disabled the short_open_tags setting (which is the default nowadays, I guess, but am not sure), so this now works for me:

---
patat:
  eval:
    php:
      command: '(echo "<?php"; cat -; echo "?>") | php'
...

# Hello world

Some PHP:

```php
print("Hello, world!");

Thanks a lot for your support! 😄
