我使用token_get_all开发工具。我陷入了一种情况,我在php代码中有以下查询
$sql = "UPDATE `key_values` SET
`Value_Content` = '" . $this->db->escape($revisionValues['value']) . "',
`Comments` = '" . $this->db->escape($revisionValues['comment']) . "',
`Is_Active` = '" . $this->db->escape($revisionValues['actstate']) . "',
`Is_Modified`='1'
WHERE
`Key_Value`='" . $candidateKey['key'] . "'
AND `Email_Template`='" . $candidateKey['template'] . "'
AND `Locale_ID`='" . $candidateKey['locale'] . "'";
和另一个代码
$array = array(
"foo" => "bar",
"bar" => "foo",
);
我想将此视为一行。如上所述,我无法检测多行代码中的行尾。有没有办法检测它。我需要一些标识符告诉我这个多行sql查询是php的一行。
答案 0 :(得分:0)
您正在制作一个声明自己声明换行符的声明。因此,您的变量包含换行符,因为您将它们放在那里。现在您有两个选择:
1:不要把换行符放在
中$sql = "UPDATE `key_values` SET ".
"`Value_Content` = '" . $this->db->escape($revisionValues['value']) . "', ".
"`Comments` = '" . $this->db->escape($revisionValues['comment']) . "', ".
"`Is_Active` = '" . $this->db->escape($revisionValues['actstate']) . "', ".
"`Is_Modified`='1' ".
"WHERE ".
"`Key_Value`='" . $candidateKey['key'] . "' ".
"AND `Email_Template`='" . $candidateKey['template'] . "' ".
"AND `Locale_ID`='" . $candidateKey['locale'] . "'";
2:在
后删除它们$sql = "UPDATE `key_values` SET
`Value_Content` = '" . $this->db->escape($revisionValues['value']) . "',
`Comments` = '" . $this->db->escape($revisionValues['comment']) . "',
`Is_Active` = '" . $this->db->escape($revisionValues['actstate']) . "',
`Is_Modified`='1'
WHERE
`Key_Value`='" . $candidateKey['key'] . "'
AND `Email_Template`='" . $candidateKey['template'] . "'
AND `Locale_ID`='" . $candidateKey['locale'] . "'";
$sql = str_replace(array(chr(10), chr(13)), '', $sql);
因此,检测换行符是检查chr(10)或chr(13)。取决于您的系统可以是其中之一,还是两者兼而有之。请参阅:Is a new line = \n OR \r\n?(\r=chr(13)
& \n=chr(10)
)
更新
如果要从token_get_all()返回单行字符串,可以使用:
<?php
$c = str_replace(array("\n","\r"), '', print_r(token_get_all('<?php echo; ?>'), true));
print $c;
// token_get_all() returns an array
// print_r(array, true) prints the array and the true param makes it return the output as a string
// replace the newline chars with nothing to make it single line
//single line output:
//Array( [0] => Array ( [0] => 372 [1] => 1 ) [1] => Array ( [0] => 316 [1] => echo [2] => 1 ) [2] => ; [3] => Array ( [0] => 375 [1] => [2] => 1 ) [4] => Array ( [0] => 374 [1] => ?> [2] => 1 ))
?>
