我正在检查我的GD库,当我运行此代码时: -
<?php
$a=gd_info();
foreach ($a as $key=>$value){
echo $key | $value . '<br>';
}
?>
它给了我以下输出:
gunvmwwio~.0.34 compatible)
w~gw~ype Supportw{umtree|y~o}gw>|s~b Supportw}fr~ead Supportw}frreate Support{|gw>Supportq~grupportw~or>Support|r>Supporty~orupport~ks?mapped Japanese Font Support
我知道如何获得正确的输出。但我只是想知道这个输出的确切含义。

首先,您创建的乱码文本并不完全正确。要正确显示正确的值,请正确包装引号:
$a = gd_info();
foreach ($a as $key=>$value){
echo "$key | $value <br/>";
// wrap them all including the pipe
}
所以作为回报,你会得到这样的东西:
// the actual correct output
