How can I remove spaces in Mysql fuzzy search?

Why does Mysql fuzzy query remove spaces ?? $ SQL = & quot; SELECTmingcFROMinfoWHERE1 = 1 & quot; fuzzy judgment if ($ mingc! = & Quot;) {& nbsp; $ SQL. = & quot; ANDmingclike Mysql fuzzy query to remove spaces question ??
$ SQL = "SELECT mingc FROM info WHERE 1 = 1 ";

Fuzzy Judgment
If ($ mingc! = ""){
$ SQL. = "AND mingc like '% $ mingc % '";
}

Trim ($ mingc)

But the problem is that = first, a space is used to enter the fuzzy condition/or the opposite.

[That is, the left and right spaces are removed at the same time and fuzzy query can be performed]

Wait .......

------ Solution --------------------
Trim () is to remove leading and trailing spaces. what happened today?
------ Solution --------------------
If (! Empty ($ mingc )){
$ SQL. = "AND mingc like '% trim ($ mingc) % '";
}
