Question

'<a href="javascript:void(0)" onClick="function(\''.$row['STUID'].'\')">Print STUDENT DETAILS</a>';

这是在语句

中传递单引号和双引号的正确方法吗？

Answer 1

是的，确实如此。首先，您转义传递给输出的单引号，并引用函数参数。在它们内部，你有引号将你的字符串与php变量分开。

你不必转义php字符串中的双引号，因为它是单引号分隔的。

$string = "this is a 'valid' string.";
$string = 'this is a \'valid\' string.';
$string = 'this is a "valid" string.';
$string = "this is a \"valid\" string.";
$valid = "valid";
$string = "this is a '".$valid."' string.";
$string = 'this is a \''.$valid.'\' string.';
$string = 'this is a "'.$valid.'" string.';
$string = "this is a \"".$valid."\" string.";
$string = "this is a '$valid' string"; //as Rocket said
$string = 'this is NOT a "$valid" string'; //Works only in double quotes
$string = "this is a '{$row['valid']}' string"; //as Rocket said

Answer 2

是肯定的。单引号和双引号之间的区别在于php将尝试解释双引号内的特殊字符和变量。但变量解释不适用于数组。
