phplint未声明函数

Question

我使用phplint检查我的PHP代码。我是om Windows 8.1，我的编辑器是崇高文本3。下面是我的一个代码片段：

<?php
header("Content-type: image/png");

$singleHeight = 129;
$singleWidth = 97;
$bild = imagecreatetruecolor(1170, 520);
$orange = imagecolorallocate($bild, 248, 154, 38);
imagefill($bild, 0, 0, $orange);

....

?>

这是phplint报告：

1:函数'header()‘(仍然)未声明。从它的用法中猜测签名。提示:最好在函数使用之前声明它们

 1: undeclared function 'header()' used only once: misspelled?

 3: variable '$singleHeight' assigned but never used

 4: variable '$singleWidth' assigned but never used

 5: function 'imagecreatetruecolor()' (still) not declared. Guessing signature from its usage. Hint: it's better to declare the functions before their usage

 5: undeclared function 'imagecreatetruecolor()' used only once: misspelled?

 6: function 'imagecolorallocate()' (still) not declared. Guessing signature from its usage. Hint: it's better to declare the functions before their usage

 6: undeclared function 'imagecolorallocate()' used only once: misspelled?     7: function 'imagefill()' (still) not declared. Guessing signature from its usage. Hint: it's better to declare the functions before their usage

 7: undeclared function 'imagefill()' used only once: misspelled?

那些未声明的函数是什么？代码本身运行良好。

我假设你在使用这个PHPLint http://www.icosaedro.it/phplint/phplint-on-line.html？

默认情况下，它似乎没有加载任何标准库，所以当您检查linter从零开始的代码时，没有任何声明。

当您在服务器上运行代码时，启用了GD和标准PHP函数(如header )，这样就可以正常工作了。

您可以将这些库添加到代码的顶部，如下所示

<?php /*. require_module 'gd'; .*/ ?>
<?php /*. require_module 'standard'; .*/ ?>
<?php
header("Content-type: image/png");

$singleHeight = 129;
$singleWidth = 97;
$bild = imagecreatetruecolor(1170, 520);
$orange = imagecolorallocate($bild, 248, 154, 38);
imagefill($bild, 0, 0, $orange);

这将像这样输出

2:      <?php /*. require_module 'standard'; .*/ ?>
3:      <?php
4:      header("Content-type: image/png");
5:      
6:      $singleHeight = 129;
7:      $singleWidth = 97;
8:      $bild = imagecreatetruecolor(1170, 520);
9:      $orange = imagecolorallocate($bild, 248, 154, 38);
10:     imagefill($bild, 0, 0, $orange);
