each ( function ( index, value ) ) Īnd we’ll obtain this on the console: Red You'll need more comprehensive protection if you plan to allow links in your text.The following example selects every element on a web page and outputs the index and the ID of each of them: // DOM ELEMENTS $ ( 'div' ). Note that allowing anchor tags or href attributes opens another potential security hole that this solution won't protect against.
If you only allow formatting tags such as b, i, and p, and styling attributes such as class, id and style, this will strip all javascript including event triggers in formatting tags. Since strip_tags does not remove attributes and thus creates a potential XSS security hole, here is a small function I wrote to allow only specific tags with specific attributes and strip all other tags and attributes. Pre-5.3.4: strip_tags('Hello World','') => 'Hello World' // strips because it wasn't explicitly specified in allowable_tagsĥ.3.4 and later: strip_tags('Hello World','') => 'Hello World' // does not strip because PHP matches it with in allowable_tags So what reads as "no longer strips self-closing tags (unless the self-closing XHTML tag is also given in allowable_tags)" is actually saying "no longer (strips self-closing tags unless the self-closing XHTML tag is also given in allowable_tags)". What it means is, in versions prior to 5.3.4, it "strips self-closing XHTML tags unless the self-closing XHTML tag is also given in allowable_tags", and that since 5.3.4 this is no longer the case. In addition, you can leave the start, condition, and increment empty, indicating that PHP should do nothing for that phase. but that's not actually what they're trying to say. PHP allows you to specify multiple expressions in the start, condition, and increment of the for statement. The above seems to be saying that, since 5.3.4, if you don't specify "" in allowable_tags then "" will not be stripped. "5.3.4 strip_tags() no longer strips self-closing XHTML tags unless the self-closing XHTML tag is also given in allowable_tags."
then remove control characters and multiple spaces
