我发现我使用的脚本已经停止工作,因为'ereg'不再支持php ...我自己没有写这个脚本但是不能为我的生活弄清楚在哪里放置分隔符。
我已经分别用'preg_match'和'preg_replace'改变了'ereg'和'ereg_replace'。
function checkPostcode($toCheck) {
$orig = $toCheck;
// Permitted letters depend upon their position in the postcode.
$alpha1 = "[abcdefghijklmnoprstuwyz]"; // Character 1
$alpha2 = "[abcdefghklmnopqrstuvwxy]"; // Character 2
$alpha3 = "[abcdefghjkstuw]"; // Character 3
$alpha4 = "[abehmnprvwxy]"; // Character 4
$alpha5 = "[abdefghjlnpqrstuwxyz]"; // Character 5
// Expression for postcodes: AN NAA, ANN NAA, AAN NAA, and AANN NAA
$pcexp[0] = '^('.$alpha1.'{1}'.$alpha2.'{0,1}[0-9]{1,2})([0-9]{1}'.$alpha5.'{2})$';
// Expression for postcodes: ANA NAA
$pcexp[1] = '^('.$alpha1.'{1}[0-9]{1}'.$alpha3.'{1})([0-9]{1}'.$alpha5.'{2})$';
// Expression for postcodes: AANA NAA
$pcexp[2] = '^('.$alpha1.'{1}'.$alpha2.'[0-9]{1}'.$alpha4.')([0-9]{1}'.$alpha5.'{2})$';
// Exception for the special postcode GIR 0AA
$pcexp[3] = '^(gir)(0aa)$';
// Standard BFPO numbers
$pcexp[4] = '^(bfpo)([0-9]{1,4})$';
// c/o BFPO numbers
$pcexp[5] = '^(bfpo)(c\/o[0-9]{1,3})$';
// Load up the string to check, converting into lowercase and removing spaces
$postcode = strtolower($toCheck);
$postcode = str_replace (' ', '', $postcode);
// Assume we are not going to find a valid postcode
$valid = false;
// Check the string against the six types of postcodes
foreach ($pcexp as $regexp) {
if (preg_ma($regexp,$postcode, $matches)) {
// Load new postcode back into the form element
$toCheck = strtoupper ($matches[1] . ' ' . $matches [2]);
// Take account of the special BFPO c/o format
$toCheck = preg_replace ('C\/O', 'c/o ', $toCheck);
// Remember that we have found that the code is valid and break from loop
$valid = true;
break;
}
}
非常感谢任何帮助。

分隔符应该包含正则表达式,因此必须将其放在$pcexp[0]
和$pcexp[1]
中。

分隔符是正则表达式模式字符串开头和结尾的一对字符。标准分隔符是/
,但如果您愿意,可以使用其他分隔符。
所以,例如:
'^(bfpo)([0-9]{1,4})$'
应更改为:
'/^(bfpo)([0-9]{1,4})$/'
^ ^
added this and this
如上所述,我在字符串的开头和结尾添加了/
。如果您愿意,可以使用#
或~
或各种其他字符作为分隔符。
请务必转义字符串中出现的分隔符字符,否则它将被视为结束分隔符。
