在php中替换一组2个双引号

Question

I have a series of strings that I have read in with fgets() from a .csv file, and then exploded into an array. The file has the csv standard double quotes. For example:

<a href=""http://www.youtube.com/watch?v=HqaemO-lI8s#t=16m6s"" target=_blank"">video</a>

is one of the values that I am reading in. I need all instances of "" to be replaced by just ". I know that this is a simple solution, but I can't seem to wrap my head around the way that the escape characters would work.

Answer 1

Use str_replace:

$string = '<a href="""">test</a>';
$string = str_replace('""', '"', $string);

echo $string;

// Outputs: <a href="">test</a>
