Question

preg_replace("/(\'\\$[^,]+)/e" , "stripslashes(trim('\\1','\''));", var_export($t, true))

preg_replace_callback()替换方法。网上找的都不成功

Answer 1

php版本估计是5.5以上了，preg_replace的修饰符e已经不能用了；
如果要调整可以用preg_replace_callback或者其他函数调整：
把
$out = "<?php \n" . '$k = ' . preg_replace("/(\'\\$[^,]+)/e" , "stripslashes(trim('\\1','\''));", var_export($t, true)) . ";\n";
修改成
$out = "<?php \n" . '$k = ' . preg_replace_callback("/(\'\\$[^,]+)/", function($r) { return stripslashes(trim($r[1],'\'')); }, var_export($t, true)). ";\n";
