Compile a string of PHP code and return the resulting op array (PECL parsekit:0.2-1.2)
array parsekit_compile_string ( string phpcode [, array &errors [, int options]] )

Warning:

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

Parameters

phpcode

A string containing phpcode. Similar to the argument to eval().

errors

A 2D hash of errors (including fatal errors) encountered during compilation. Returned by reference.

options

One of either PARSEKIT_QUIET or PARSEKIT_SIMPLE. To produce varying degrees of verbosity in the returned output.

Return Values

Returns a complex multi-layer array structure as detailed below.

Examples

Example 1708. parsekit_compile_string() example

<?php
 $ops
= parsekit_compile_string('
echo "Foo\n";
'
, $errors, PARSEKIT_QUIET);

 
var_dump($ops);
?>

The above example will output:
