parsekit_compile_string — Compile a string of PHP code and return the resulting op array
$phpcode
[, array &$errors
[, int $options
= PARSEKIT_QUIET
]] )此函数是实验性的。此函数的表象,包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。
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.
Returns a complex multi-layer array structure as detailed below.
Example #1 parsekit_compile_string() example
<?php
$ops = parsekit_compile_string ( '
echo "Foo\n";
' , $errors , PARSEKIT_QUIET );
var_dump ( $ops );
?>
以上例程会输出:
array(20) { ["type"]=> int(4) ["type_name"]=> string(14) "ZEND_EVAL_CODE" ["fn_flags"]=> int(0) ["num_args"]=> int(0) ["required_num_args"]=> int(0) ["pass_rest_by_reference"]=> bool(false) ["uses_this"]=> bool(false) ["line_start"]=> int(0) ["line_end"]=> int(0) ["return_reference"]=> bool(false) ["refcount"]=> int(1) ["last"]=> int(3) ["size"]=> int(3) ["T"]=> int(0) ["last_brk_cont"]=> int(0) ["current_brk_cont"]=> int(-1) ["backpatch_count"]=> int(0) ["done_pass_two"]=> bool(true) ["filename"]=> string(17) "Parsekit Compiler" ["opcodes"]=> array(3) { [8594800]=> array(5) { ["opcode"]=> int(40) ["opcode_name"]=> string(9) "ZEND_ECHO" ["flags"]=> int(768) ["op1"]=> array(3) { ["type"]=> int(1) ["type_name"]=> string(8) "IS_CONST" ["constant"]=> &string(4) "Foo " } ["lineno"]=> int(2) } ["859484C"]=> array(6) { ["opcode"]=> int(62) ["opcode_name"]=> string(11) "ZEND_RETURN" ["flags"]=> int(16777984) ["op1"]=> array(3) { ["type"]=> int(1) ["type_name"]=> string(8) "IS_CONST" ["constant"]=> &NULL } ["extended_value"]=> int(0) ["lineno"]=> int(3) } [8594898]=> array(4) { ["opcode"]=> int(149) ["opcode_name"]=> string(21) "ZEND_HANDLE_EXCEPTION" ["flags"]=> int(0) ["lineno"]=> int(3) } } }
