Php MySQLi使用引号等更新

我试图用PHP更新Joomla模块，但是参数字段充满了引号和单引号

这是原始的MySQL查询。如何在PHP中使用所有的引号和单引号进行查询

UPDATE `xxyyzz_modules` 
SET `params` = '{"moduleclass_sfx":"","loadJQuery":"1","tableType":"datatable","theme":"ui-lightness","source":"sql","title":"","className":"arttable_table","tablecode":"","sqlQuery":"SELECT * FROM `xxyyzz_dtregister_paymentdetailsuser` WHERE datetime between ''2014\\/02\\/16'' and ''2014\\/03\\/02''","csscode":"","connectionString":"","csvFile":"","csvDelimiter":",","convertLinks":"2","linkConversionPattern":"TITLE|URL","linksNofollow":"0","linksNewWindow":"0","showFirstLink":"0","searchText":"Search:","searchSize":"15","headerStyle":"","cellStyle":"","excel":"","chartType":"LineChart","chartLeftHeader":"","xAxis":"","yAxis":"","chartWidth":"1100","chartHeight":"300","hideTable":"1","module_tag":"div","bootstrap_size":"0","header_tag":"h3","header_class":"","style":"0"}' 
WHERE `id` =140;

您需要转义用于分隔PHP字符串的任何类型的引号

$sql = 'UPDATE `xxyyzz_modules`
        SET `params` = \'{"moduleclass_sfx":"","loadJQuery":"1","tableType":"datatable","theme":"ui-lightness","source":"sql","title":"","className":"arttable_table","tablecode":"","sqlQuery":"SELECT * FROM `xxyyzz_dtregister_paymentdetailsuser` WHERE datetime between \'\'2014\\/02\\/16\'\' and \'\'2014\\/03\\/02\'\'","csscode":"","connectionString":"","csvFile":"","csvDelimiter":",","convertLinks":"2","linkConversionPattern":"TITLE|URL","linksNofollow":"0","linksNewWindow":"0","showFirstLink":"0","searchText":"Search:","searchSize":"15","headerStyle":"","cellStyle":"","excel":"","chartType":"LineChart","chartLeftHeader":"","xAxis":"","yAxis":"","chartWidth":"1100","chartHeight":"300","hideTable":"1","module_tag":"div","bootstrap_size":"0","header_tag":"h3","header_class":"","style":"0"}\'
        WHERE `id` =140;';

或

或使用此处文档：

$sql = <<'EOS'
       UPDATE `xxyyzz_modules`
       SET `params` = '{"moduleclass_sfx":"","loadJQuery":"1","tableType":"datatable","theme":"ui-lightness","source":"sql","title":"","className":"arttable_table","tablecode":"","sqlQuery":"SELECT * FROM `xxyyzz_dtregister_paymentdetailsuser` WHERE datetime between ''2014\\/02\\/16'' and ''2014\\/03\\/02''","csscode":"","connectionString":"","csvFile":"","csvDelimiter":",","convertLinks":"2","linkConversionPattern":"TITLE|URL","linksNofollow":"0","linksNewWindow":"0","showFirstLink":"0","searchText":"Search:","searchSize":"15","headerStyle":"","cellStyle":"","excel":"","chartType":"LineChart","chartLeftHeader":"","xAxis":"","yAxis":"","chartWidth":"1100","chartHeight":"300","hideTable":"1","module_tag":"div","bootstrap_size":"0","header_tag":"h3","header_class":"","style":"0"}'
       WHERE `id` =140;
EOS;

$sql=而不是手动转义字符串：

$json = '{"moduleclass_sfx":"","loadJQuery":"1","tableType":"datatable","theme":"ui-lightness","source":"sql","title":"","className":"arttable_table","tablecode":"","sqlQuery":"SELECT * FROM `xxyyzz_dtregister_paymentdetailsuser` WHERE datetime between ''2014\\/02\\/16'' and ''2014\\/03\\/02''","csscode":"","connectionString":"","csvFile":"","csvDelimiter":",","convertLinks":"2","linkConversionPattern":"TITLE|URL","linksNofollow":"0","linksNewWindow":"0","showFirstLink":"0","searchText":"Search:","searchSize":"15","headerStyle":"","cellStyle":"","excel":"","chartType":"LineChart","chartLeftHeader":"","xAxis":"","yAxis":"","chartWidth":"1100","chartHeight":"300","hideTable":"1","module_tag":"div","bootstrap_size":"0","header_tag":"h3","header_class":"","style":"0"}' 

$sql = "UPDATE `xxyyzz_modules` 
SET `params` = '" . mysqli_real_escape_string($json) . "'
WHERE `id` =140";

第二个选项无错误地通过，但不执行更新。参数中包含mysql查询是否有问题？我认为不应该有问题。就MySQL而言，它只是一个字符串。如果您没有从MySQL中得到错误，那么它不更新的唯一原因就是没有id=140的行。啊，您还需要避开字符串中的反斜杠。我建议使用here doc来避免所有这些问题。
