    <p>Perhaps simply</p> <pre><code>preg_match('/[0-9]*/', $output, $matches); </code></pre> <p>If I'm not mistaken...<br/></p> <p>To be sure:</p> <pre><code>preg_match('Counts is :([0-9]*)[^0-9]*([0-9]*)/',$output,$matches); </code></pre> <p>Also have a look <a href="https://stackoverflow.com/questions/17468367/interactive-control-of-a-program-using-php#comment25384148_17468367">at this question</a> to find ouy how to use PHP and C(++) interactively</p> <p>A quick, and hacky ugly messy workaround could be:</p> <pre><code>printf("%d",ar[0]); return ar[1];//end main function </code></pre> <p>Then, in your PHP script:</p> <pre><code>$a = array(shell_exec('/home/technoworld/Videos/LinSocket/client "nice bad"'), shel_exec('echo $?'); ); </code></pre> <p>Then get the last numeric value from the output string, (<code>preg_match('/([0-9]*)\w*$/',$a[0],$matches);</code> should do it, and <code>$a[1]</code> will contain the value of <code>ar[1]</code> of the main.cpp file, because that was the exit code. Note that exit codes <em>aren't for show</em>. The signify something! Changeing them is generally a bad idea. I'd just change my main.cpp, and add the line:</p> <pre><code>printf("@ar[0]=%d;ar[1]=%d@",ar[0],ar[1]); </code></pre> <p>This prints a clearly formatted string, which is easy to parse using a regular expression. Assuming <code>*ar</code> held values 123 and 456 respectively:</p> <pre><code>preg_match_all('/\]\=([^;@]*)/',$a[0],$matches); var_dump($matches[1]);//[123,456] </code></pre> <p>Or better stil:</p> <pre><code>$parts = explode('@', $a[0]); echo $parts[1];//ar[0]=123;ar[1]=456 </code></pre> <p>Bottom line:</p> <p>Add this to your <code>main</code> function in <em>main.cpp</em>:</p> <pre><code>printf("@ar[0]=%d;ar[1]=%d@",ar[0],ar[1]); </code></pre> <p>and, to get the int values in php:</p> <pre><code>$a = array(shell_exec('..')); preg_match_all('/[^=]*\=([^;@]*)/',$a[0],$matches); var_dump($matches[1]); </code></pre> <p>That should do it.</p> <pre><code>$a = array(); $b = array(); if (preg_match_all('/[^=]*\=([^;@]*)/', shell_exec('your command'), $matches)) { $a[] = (int) $matches[1][0];//optionally cast to int $b[] = (int) $matches[1][1]; } </code></pre> <p>That's all... not sure why <code>$a</code> and <code>$b</code> need to be arrays, but that's probably because you're going to call the <code>client</code> bin a couple of times.</p>

    1. COThanks dear but I dont want to make that much complicated, my purpose is different so I just want to access the ar[] values!

    2. CO@user174889: Well, you can't access the stack of your program through a php script. You just can't. You'll either have to write a function like `void getAr(int idx){ printf("%d", ar[idx]);}`, where `*ar` needs to be in scope, obviously... or you're going to have to parse the `main` functions output

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
