POSearching for a substring inside an array in php
text
Body
copied!<p>Hi I would like to know if there is a good algorithm to the search of a substring inside an array that is inside another array,</p> <p>I have something like:</p> <p>Array(</p> <pre><code> [0] => Array( [0] => img src="1" /> [1] => img src="2" alt="" class="logo i-dd-logo" /> [2] => img src="3" alt="" /> [3] => img src="4" width="21" height="21" alt="" class="i-twitter-xs" /> [4] => img src="myTarget" width="21" height="21" alt="" class="i-rss" /> [5] => <img class="offerimage" id="product-image" src="6" title="" alt=""/> [6] => <img class="offerimage" id="product-image" src="7" title="" alt=""/> [7] => <img class="offerimage" id="product-image" src="8" title="" alt=""/> [8] => <img src="9" width="16" height="16" /> ) [1] => Array( [0] => src="1" [1] => src="a" alt="" class="logo i-dd-logo" [2] => src="b" alt="" ) </code></pre> <p>)</p> <p>What I want to do is to know the position of target, for example [0][4] but it's not always the same</p> <p>What I'm doing now is a while inside another while and checking whith strpos for the substring, but maybe there is a better way to do this, any suggestions?</p> <p>Thanks for everything</p> <hr> <p>Updated code:</p> <blockquote> <p>$i=-1; </p> <p>foreach($img as$outterKey=>$outter) {</p> <pre><code> foreach($outter as $innerKey=>$inner){ $pos = strpos($img[$outterKey][$innerKey],"myTarget"); if (!$pos === false) { $i=$outterKey;$j=$innerKey; break 2; } } } </code></pre> </blockquote>
