在Sql中使用php变量

Question

i have a form that is used to set a search term to a php variable VIA _GET so for example if the user typed cat the url would say ?search=cat

Here is the PHP variable that will be used in the SQL query

$search = 'CustomerAccountName LIKE '%'  . $_GET['search'] . '%'';

When echoed this produces CustomerAccountName LIKE '%cat%' which is valid and works when using the query editor however when i try to place the $search variable in to the query in php i get this error

Warning: odbc_exec(): SQL error: [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect
 syntax near '&'., SQL state 37000 in SQLExecDirect 

any help would be much appreciated

Answer 1

Just use plain single quotes.

$search = "CustomerAccountName LIKE '%".$_GET['search']."%';";

But don't build your query like this. Sanitize it before to prevent SQL injection.
