PHP error message: Deprecated: Function eregi() is deprecated_PHP tutorial

Today when using a regular expression, I got an error message: Deprecated: Function eregi() is deprecated in. Later I found out that the reason is that our php5.3 does not support the eregi function in 5.3. You can use preg_match directly instead. .

Before changed: function inject_check($sql_str) {

代码如下	复制代码
$sql_str = strtolower($sql_str);  return eregi('fopen|post|eval|select|insert|and|or|update|delete|'|/*|*|../|./|union|into|load_file|outfile', $sql_str); // 进行过滤 }

Solution:

Find the file location where the code is located

function inject_check($sql_str) {
$sql_str = strtolower($sql_str);
return preg_match('/fopen|post|eval|select|insert|and|or|update|delete|'|/*|*|../|./|union|into|load_file|outfile/', $sql_str) ; // Filter
}

The code is as follows  代码如下 复制代码 function inject_check($sql_str) {  $sql_str = strtolower($sql_str);  return preg_match('/fopen|post|eval|select|insert|and|or|update|delete|'|/*|*|../|./|union|into|load_file|outfile/', $sql_str); // 进行过滤 }	Copy code
