Answer 1

My post is editted. See what hakre posted, it's a better answer than mine was.

string escapeshellarg ( string $arg )

Should do the trick, plus it allows you to pass a string directly to the shell function treated as a single safe argument

Answer 2

使用撇号，例如http://www.imagemagick.org/Usage/text/#label中的示例“多行标签”

$cmd = " -background transparent -font $font -pointsize $size label:'$label' -stroke black -strokewidth 2 ".

Answer 3

Put the entire string in double quotes since spaces are not allowed in command line. In the following i enclosed both usages of $label in double-quotes using the \\" escape sequence:

$label=$_POST["label"];
$cmd = " -background transparent -font $font -pointsize $size label:\"$label\" -stroke black -strokewidth 2 ".
"  \( -clone 0 -tile \"" . $image . "[0]\" -stroke black -strokewidth 2 -gravity center -annotate +0+0 \"$label\" \) ".
